Descriptions
Type: Lignicolous Fungi; Description: Basidiomata annual, centrally or laterally stipitate, occasionally sessile, usually solitary but sometimes with two or three pilei arising from a common base. Pileus, when centrally stipitate, circular or somewhat funnel-shaped, plane, 30–120 mm wide; when laterally stipitate, fan-shaped, 50–110 mm wide, 5–15 mm thick; sessile forms dimidiate. Pileus surface even or warty, finely tomentose, brown, reddish brown or pale straw-coloured, margin entire or lobed, often inturned.

Distribution: Northland, Auckland, Waikato, Bay of Plenty, Taranaki, Taupo, Wanganui, Wellington, Gisborne, Hawkes Bay, Wairarapa, Nelson, Mid Canterbury, South Canterbury.; 1st Record: Colenso (1891: as Agaricus (Pholiota) pudicus (see Watling & Taylor 1987)).
Significance: A very large agaric, not uncommonly seen fruiting on wounds on living trees. It causes a heart rot and may invade sapwood. It is considered to be a weak parasite (Hood 1992).; Host(s): Alectryon excelsus, Beilschmiedia tawa, Carpodetus serratus, Corynocarpus laevigatus, Dysoxylum spectabile, Erythrina caffra, Hoheria sp., Kunzea ericoides, Laurelia novaezelandiae, Macropiper excelsum, Magnolia grandiflora, Melicytus ramiflorus, Metrosideros excelsa, Nothofagus solandri var. solandri, Plagianthus regius, Populus nigra, Rhododendron sp., Ulmus sp.

Distribution: Bay of Plenty, Taupo, Wanganui, Wellington, Gisborne, Hawkes Bay, Wairarapa, Nelson, Buller, Westland, Marlborough Sounds, Marlborough, North Canterbury, Mid Canterbury, Dunedin, Southland.; 1st Record: Birch (1935: as Phomopsis strobi).
Significance: Although it is not a primary parasite, this fungus aggravates damage caused by frost. The resulting dieback of branches and terminal shoots often leads to malformation but rarely causes mortality, except in young seedlings. Between 1925 and 1935 the fungus caused considerable damage to young (1–10 years old) Pinus radiata plantations on frost flats at altitudes of 600 m and above in central North Island (Birch 1935). Changes in silvicultural practices have reduced the incidence of frost damage and the fungus is now only of minor importance. It is occasionally reported from sites subject to heavy frosts in late spring, particularly those where windrowing has been carried out or hardening-off of nursery stock has been neglected.; Host(s): Pinus canariensis, P. muricata, P. radiata, Pseudotsuga menziesii.
Type: Foliicolous Fungi; Description: Mycelium black to olivaceous black. Conidiophores in small groups or solitary, straight or flexuous, olivaceous to golden brown, smooth, up to 50 μm long.

Distribution: Northland, Auckland, Waikato, Bay of Plenty, Wanganui, Wellington, Hawkes Bay, Nelson, Marlborough, Mid Canterbury.; 1st Record: Kidd (1929: as Alternaria tenuis).
Significance: A very common saprobe found on many plants. It causes a storage rot in apples, which is of minor significance (Kidd 1929).; Host(s): Actinidia deliciosa, Malus ×domestica, Prunus armeniaca.
Type: Foliicolous Fungi; Description: Mycelium olivaceous to black. Conidiophores solitary, straight or flexuous, pale to mid brown or olivaceous brown, up to 300 sm long.

Distribution: Northland, Auckland, Bay of Plenty.; 1st Record: Cunningham (1931b).
Significance: Found on leaves and fruit of Citrus spp., causing scabbing and discolouration of fruit (Dingley 1969). It is of minor importance.; Host(s): Citrus grandis × reticulata, C. jambhiri, C. sinensis.
Type: Foliicolous Fungi; Description: Colonies on agar subhyaline, loosely woolly. Conidiophores of two types: primary conidiophores in small groups, simple, 100–250 μm long; secondary conidiophores produced from primary conidia, simple, 50–120 μm long. Conidia of two types: primary conidia narrowly elliptical, 3–7-septate, without longitudinal septa, 25–40 × 6–8 μm, smooth to verruculose, subhyaline to pale tan; secondary conidia ellipsoid to ovoid, in short chains, 1–4-septate, rarely with one longitudinal septum in one transverse segment, 12–20 × 5–8 μm, smooth, pale tan.
Distribution: Auckland.; 1st Record: Simmons (2002).

Distribution: Northland, Auckland, Bay of Plenty.; 1st Record: Hill (1979: as Alternaria raphani).
Significance: None.; Host(s): Fatsia japonica, Meryta sinclarii, Pseudopanax laetus, P. lessonii.
Type: Foliicolous Fungi; Description: Mycelium olivaceous. Conidiophores in groups or solitary, straight or flexuous, pale brown to mid brown, smooth, up to 115 μm long. Conidia obclavate, or with the body of the conidium ellipsoidal tapering gradually to the beak which is up to half the length of the conidium, straight or slightly curved, solitary or in short chains, with 4–7 transverse and several longitudinal and oblique septa, 22–95 × 8–19 μm, smooth to minutely verruculose, pale to mid golden brown.

Gills crowded, free, white. Stipe tapering slightly towards the pileus from a bulbous base, white and striate above a membranaceous white to yellowish annulus, white to dirty white below, hollow, up to 170 mm long. Basidiospores subglobose to broadly ellipsoid, 0-septate, 9–11 × 7–8 μm, hyaline, non-amyloid; spore print white.
Distribution: Northland, Auckland, Coromandel, Waikato, Bay of Plenty, Taranaki, Taupo, Wanganui, Wellington, Gisborne, Hawkes Bay, Wairarapa, Nelson, Fiordland, Marlborough, North Canterbury, Mid Canterbury, Dunedin, Southland, Chatham Islands.; 1st Record: Birch (1937).
Significance: This is the classic toadstool familiar to everyone. It is one of the most common and striking agarics associated with introduced tree species in New Zealand. Unlike most introduced mycorrhizal fungi, it has been recorded in indigenous forests in association with Nothofagus and Leptospermum (Stevenson 1962, Horak 1971). Recent reports (Johnston et al. 1998; Orlovich & Cairney 2004) indicate A. muscaria may be locally common in Nothofagus forests in several areas in the South Island. The fungus was isolated from, and experimentally shown to be, a mycorrhizal partner of Pinus radiata (Chu-Chou 1979) and Pseudotsuga menziesii (Chu-Chou & Grace 1981c). It has not been recorded in nurseries and is found only in older (>6-year-old) plantations (Chu-Chou & Grace 1988).; Host(s): Arbutus sp., Betula pendula, Castanea sativa, Eucalyptus ficifolia, E. pauciflora subsp. pauciflora, Fagus sylvatica, Larix decidua, Nothofagus fusca, N. menziesii, N. solandri var. solandri, N. solandri var. cliffortioides, Pinus nigra subsp. laricio, P. radiata, Pseudotsuga menziesii, Quercus robur.
Type: Caulicolous Fungi; Description: Basidiomata perennial, effused-reflexed, pileate. Pilei projecting 10–30 mm from the substrate, separate or clustered, 50–100 mm in diameter, 1–2 mm thick. Pileus surface irregular, finely tomentose, rusty brown to dark brown, margin lighter. Pore surface grey to brown-violet with a lilac tinge, later ochraceous brown, smooth to tuberculate, margin somewhat thickened and finely tomentose. Hyphal system dimitic. Cystidia abundant, encrusted, 40–60 × 6–9 μm, yellowish brown. Basidio-spores cylindrical to narrowly ellipsoid, 5–7 × 2–3 μm, hyaline, smooth. Arthrospores produced in special intersegmental sacs of the adult female wood wasp Sirex noctilio.
Distribution: Northland, Auckland, Coromandel, Waikato, Bay of Plenty, Taranaki, Taupo, Rangitikei, Wanganui, Wellington, Gisborne, Hawkes Bay, Wairarapa, Nelson, Buller, Westland, Marlborough, North Canterbury, Mid Canterbury, South Canterbury, Central Otago, Dunedin, Southland.; 1st Record: Clark (1933: as ‘the Sirex fungus’).
Significance: The fungus, which is carried by the adult female wood wasp Sirex noctilio Fabricius in special intersegmental sacs, causes a sudden wilt disease of exotic conifers in New Zealand. Arthrospores and a toxic mucus are deposited along with an egg by the ovipositing insect in tunnels made in tree stems. The mucus causes wilting and yellowing of foliage. It facilitates spread of the fungus, which rapidly kills cambium cells and invades the wood, disrupting water movement. The combined effect of mucus and fungus can kill a tree weakened by drought, suppression, or subjected to massive oviposition. Although present in New Zealand at least since 1900 (Miller & Clark 1935), the first major outbreak did not occur until 1946. By 1951, 25–30% of Pinus radiata trees growing on about 100,000 ha had been killed. Shortage of labour in New Zealand during the Second World War meant that most tree stands were untended and heavily overstocked. Most of the trees killed had been suppressed and mortality was beneficial because it provided a much-needed light thinning. At present, Sirex noctilio populations are controlled by the introduced larval parasitoids Rhyssa persuasoria persuasoria (Linnaeus), Megarhyssa nortoni nortoni (Cresson) and Ibalia leucospoides leucospoides (Hochenwarth) and the nematode Deladenus siricidicola Bedding which parasitises ovaries and renders the female wasps sterile. Currently, the presence of the fungus is unimportant in well-tended stands. Occasional local outbreaks after long periods of drought have been short-lived and the damage caused has been minor.; Host(s): Resistant i.e., attacked, but suffering little damage: Abies sp., Larix decidua, L. kaempferi, Picea abies, P. sitchensis, Pseudotsuga menziesii. Moderately resistant: Pinus palustris, P. pinaster. Susceptible: Pinus contorta, P. echinata, P. elliottii, P. muricata, P. nigra subsp. nigra, P. nigra subsp. laricio, P. patula, P. ponderosa, P. radiata, P. strobus, P. sylvestris, P. taeda.
Type: Sooty Moulds and Similar Fungi; Description: Subiculum compacted into spongy masses, extensive, up to 1 mm thick, black; on branches. Mycelium composed of pale brown to brown, septate, coarsely warted, straight or curved, 10–14 μm wide hyphae.

Distribution: Mid Canterbury.; 1st Record: Hughes (1974a).
Significance: None.; Host(s): Melicope simplex.
Type: Sooty Moulds and Similar Fungi; Description: Subiculum in spongy mounds up to 1 mm thick, dark brown to black; on branches. Mycelium composed of pale brown to dark brown, septate, coarsely warted, straight or gently curved, 12–18 μm wide hyphae. Conidia narrowly ellipsoidal to cylindrical, curved, 11–18-septate, 100–150 × 12–16 μm, smooth, pale brown to brown.
Distribution: Buller, Mid Canterbury.; 1st Record: Hughes (1974a).
Significance: None.; Host(s): Nothofagus fusca.
Type: Sooty Moulds and Similar Fungi; Description: Subiculum superficial, loose or compact, spongy, up to 2 mm thick and extending for 30–40 mm, black; on twigs.

Distribution: Mid Canterbury.; 1st Record: Hughes (1974a).
Significance: None.; Host(s): Myrsine australis.
Type: Foliicolous Fungi; Description: Ascomata perithecial, scattered, immersed, globose or slightly flattened at the base, black, 0.2–0.3 mm in diameter, with a protuberant neck 80–124 m long; on the lower surfaces of fallen leaves.

Conidiomata acervular, yellowish brown, on elongated, vein-limited, brown necrotic areas on attached leaves. Conidia ovoid to elliptical, 0-septate, 6–16 × 3–6 μm, smooth, hyaline.
Distribution: Northland, Auckland, Waikato, Bay of Plenty, Wellington, Hawkes Bay, Nelson, Mid Canterbury, South Canterbury.; 1st Record: Brien (1939: as Gloeosporium nervisequum).
Significance: The cause of anthracnose of planes, causing serious damage in Platanus ×acerifolia (London plane) in occasional years. Symptoms of the disease have been described in detail by Neely (1976). The first evidence of infection is usually bud blight in early spring. The bud and sometimes the twig bearing the bud may be killed; if not, the fungus may invade shoot tissues after the buds have flushed, causing shoot blight to develop. The fungus also infects leaves during the summer and causes leaf blight.; Host(s): Platanus ×acerifolia, P. occidentalis, P. orientalis.
Type: Radicicolous Fungi; Description: Basidiomata pileate, centrally stipitate. Pileus 20–80 mm in diameter, light brown to umber, becoming dark brown to vinaceous tawny later, with dark brown to smoky black scales sprinkled thickly at centre and more sparsely towards the margin, convex at first, becoming plano-convex to irregularly depressed later, dry; flesh firm, ivory, sometimes with a pinkish tinge. Gills sinuate to sub-decurrent, moderately crowded, vinaceous buff to russet to fawn. Stipe tapering towards a sub-bulbous base, buff to fawn in the upper third, sepia or cigar brown further down, fibrillose, solid, 30–70 mm long. Basidiospores broadly ellipsoid to ovoid, 6–9 × 4–6 μm, non-amyloid; spore print white.
Distribution: Buller, Westland.; 1st Record: Kile & Watling (1983).
Significance: Recorded only from Nothofagus forests of the north west coast of the South Island. Studies using molecular techniques (Coetzee et al. 2001) have shown that A. hinnulea is more closely related to Armillaria spp. occurring in the Northern Hemisphere than to other Australian and New Zealand species. Armillaria hinnulea also occurs in the mixed forest and wet sclerophyll eucalypt forest of south-eastern Australia where hosts include Acacia melanoxylon, Eucalyptus regnans, and Nothofagus cunninghamii.; Host(s): Nothofagus solandri var. cliffortioides, Nothofagus sp.
Type: Radicicolous Fungi; Description: Basidiomata pileate, centrally stipitate. Pileus 80–130 mm in diameter, lemon yellow, with dark brown tufted scales sprinkled thickly at centre and more sparsely towards the margin, convex at first, becoming almost plane later, dry; flesh firm, white. Gills sinuately decurrent, moderately crowded, creamy white, becoming pinkish fawn. Stipe tapering towards the pileus, with a bulbous base, light brown above a substantial floccose annulus, shading to brown or olive green below, velutinate, solid, 100–150 mm long. Basidiospores ovoid, 7–8 × 5–7 m, non-amyloid; spore print white.
Distribution: See Significance.; 1st Record: Stevenson (1964: as Armillariella limonea).
Significance: In older records (Gilmour 1966a; Dingley 1969), Armillaria limonea and A. novaezelandiae were collectively referred to as Armillaria mellea, a European species not known from New Zealand. Most records of disease attributed to infection by Armillaria (clearly recognisable from the presence of rhizomorphs and fan-like mycelial sheets under bark) do not identify the species as it is not possible to do so in the absence of fruiting bodies. No distinction between the two species is made in the account that follows. Shaw et al. (1981) found no significant difference between them in terms of pathogenicity. Hood & Sandberg (1993), using a large number of isolates in pot tests, found that A. limonea was generally slightly less pathogenic to Pinus radiata than A. novaezelandiae. They also found considerable variability in pathogenicity between different isolates of the same species. Armillaria limonea and A. novaezelandiae are endemic in New Zealand, fruiting bodies and rhizomorphs of both species being common in indigenous forests. They are apparently unable to parasitise roots in podocarp/hardwood forests where there is no evidence of mortality caused by Armillaria spp. Parasitic attack has been reported in Nothofagus forests (Rawlings 1953). As the natural distribution of Armillaria spp. is restricted to forested areas, root disease caused by these species is a first rotation problem only in plantations established on former indigenous forest sites. In new Pinus radiata plantations established on such sites, mortality commences 3–6 months after planting and up to 10% of the trees may be killed in the first year. Mortality continues for about 10 years and may affect up to 50% over this period (Shaw & Calderon 1977). Trees older than 10 years are rarely killed but infection persists in a non-lethal, chronic form to the end of the rotation. From a country-wide survey, Self et al. (1998) found that 39% of plantation trees on formerly indigenous forest sites were chronically infected. Such trees are susceptible to windthrow and toppling and grow more slowly than uninfected trees. Estimates of volume loss attributable to Armillaria infection vary between 14–24% for individual trees (Shaw & Toes 1977) and 6–13% for a 28-year sawlog regime (MacKenzie 1987). Armillaria root disease is not a problem in first rotation Pinus radiata stands established on farmland or other sites that previously carried only herbaceous cover (Gilmour 1966a). Self et al. (1998) found that 4% of trees planted on herbaceous shrub sites were infected by Armillaria spp. There is considerable evidence to show that on such sites, stumps left when the first tree plantation crop is felled can be infected by basidiospores carried over long distances (Hood, Horner et al. 2002). Rhizomorphs are not produced for several years and thus there is little or no mortality in the second rotation crop. When rhizomorph production does occur, trees are older and have developed some resistance. Although there is no mortality, varying numbers of trees become chronically infected and there is a consequent loss of volume increment. Kimberley et al. (2002) estimated a volume loss of just over 2% in a 13-year-old second rotation stand where approximately 20% of trees carried non-lethal, chronic infection. The only proven eradicative control measure for armillaria root disease is the removal of stumps, which are the main source of inoculum (van der Pas & Hood 1984). Stumping is expensive and difficult to undertake on steep country and is rarely practiced. Application of fungicides to stumps or soil has not been effective (Shaw et al. 1980; van der Pas & Hood 1984). Inoculation of stumps with saprobic fungi immediately after felling to prevent colonisation by Armillaria spp. (Yang & Hood 1992) is being explored.

Distribution: See Significance.; 1st Record: Stevenson (1964: as Armillariella novaezelandiae).
Significance: Causes extensive vine death in kiwifruit orchards, particularly in the vicinity of stumps of felled shelterbelt trees. In older records (Gilmour 1966a; Dingley 1969), Armillaria limonea and A. novaezelandiae were collectively referred to as Armillaria mellea, a European species not known from New Zealand. Most records of disease attributed to infection by Armillaria (clearly recognisable from the presence of rhizomorphs and fan-like mycelial sheets under bark) do not identify the species as it is not possible to do so in the absence of fruiting bodies. No distinction between the two species is made in the account that follows. Shaw et al. (1981) found no significant difference between them in terms of pathogenicity. Hood & Sandberg (1993), using a large number of isolates in pot tests, found that A. limonea was generally slightly less pathogenic to Pinus radiata than A. novaezelandiae.

Significance: Commonly known as ‘grey mould’, this ubiquitous fungus is of considerable economic importance in horticulture since it damages flowers, leaves, stems, fruit, and other parts of many crop plants (Dingley 1969). In forestry, it is of importance only as a nursery pathogen causing soft rot and dieback of terminal shoots of young seedlings. Major losses are rare, but occur occasionally in glasshouse-grown stock.; Host(s): Actinidia chinensis, A. deliciosa, Adiantum sp., Anigozanthos manglesii, Araucaria araucana, Camellia japonica, Carica × heilbornii nm. pentagona, Chamaecyparis pisifera, Citrus grandis × reticulata, C. limon, C. sinensis, Clematis recta, Cryptomeria japonica, Cupressus macrocarpa, Cydonia oblonga, Cyphomandra betacea, Diospyros kaki, Eucalyptus botryoides, E. globulus subsp. maidenii, E. ovata, E. saligna, Feijoa sellowiana, Forsythia sp., Fuchsia ×hybrida, Hibiscus cannabinus, H. rosa-sinensis, Jasminum mesnyi, Lagerstroemia indica, Leucospermum nutans, L. reflexum, Lupinus angustifolius, Malus ×domestica, Mangifera indica, Passiflora edulis, Pinus brutia, P. muricata, P. nigra subsp. nigra, P. nigra subsp. laricio, P. radiata, Prunus armeniaca, P. persica, Pseudotsuga menziesii, Psidium cattleianum, Pyrus communis, Ribes nigrum, R. rubrum, R. uva-crispa var. sativum, Rosa sp., Rubus fruticosus agg., R. idaeus, Rubus × (hybrid berry), Sequoia sempervirens, Thuja plicata, Vaccinium corymbosum, Vitis labrusca × vinifera, V. vinifera.

Distribution: Northland, Auckland, Bay of Plenty, Taupo, Mid Canterbury.; 1st Record: Mulcock (1954).
Significance: This sooty mould is a highly visible, but non-parasitic, partner in the disease complex known as ‘manuka blight’. The parasitic partner and the principal villain responsible for damage to the plant is the introduced scale insect Eriococcus orariensis Hoy (Eriococcidae), which can be found all parts of the host plant but is generally more numerous on the stem where the flaky bark affords protection. ‘Honey dew’ exuded by the insect is washed down the plant by rainwater. The sooty mould lives on nutrients in the honey dew. If insect infestation is severe the whole plant may become covered with mycelium, giving it a fire-blackened appearance. The first outbreak of the scale insect has been traced back to 1936–37 in the Orari Gorge, South Canterbury (Hoy 1961). By 1950, large areas of Leptospermum scoparium (manuka) in Canterbury had been killed (Mulcock 1954). Although manuka blight had spread to most of the North Island and the eastern side of the South Island by the late 1950s, the amount of damage caused was declining as the insects became parasitised by an endemic fungus, Angatia thwaitesii (Petch) Arx (Hoy 1961). At present, manuka blight is common but rarely severe enough to cause death of the host. Leptospermum scoparium is very susceptible to E. orariensis attack but the closely related Kunzea ericoides (kanuka) is resistant. Capnodium walteri has been reported on Pinus spp. (Gilmour 1966a) but is of no importance.; Host(s): Coprosma lucida, Dracophyllum subulatum, Kunzea ericoides, Leptospermum scoparium, Ozothamnus leptophyllus, Pinus sp.

Distribution: Northland, Auckland, Waikato, Bay of Plenty, Taupo, Rangitikei, Wanganui, Gisborne, Nelson.; 1st Record: Gilmour (1965b: as Gloeosporium sp.).
Significance: Dingley & Gilmour (1972) found that isolates from lesions on seedlings of Pinus spp., identified according to morphological criteria as Colletotrichum acutatum, were pathogenic to Lupinus arboreus, L. angustifolius, Lathyrus odoratus, Pinus spp., and Vicia sativa. Isolates from the two Lupinus species growing with young P. radiata plants in the field infected P. radiata seedlings. Isolates from L. arboreus growing on sand dunes were not pathogenic to P. radiata, although they infected other legumes. Isolates from Lathyrus odoratus were pathogenic to legumes but not to pines. Isolates from ripe fruit rots were not pathogenic to either pines or legumes. Isolates from all sources caused ripe fruit rot. The forma specialis causes a serious disease known as ‘terminal crook’ in Pinus radiata seedlings. The disease is most common in young (<1 year old) seedlings but older seedlings are occasionally infected. There is no record of the disease developing in seedlings that have been planted out on a forest site. The fungus survives on plant debris in the nursery beds and conidia are dispersed by water splash. Conidia landing on terminal needles of young seedlings germinate and hyphae quickly penetrate the stem, usually killing immature tissue on one side only. Uninjured tissue continues to grow and the terminal shoot curves over, assuming the typical shepherd’s crook shape. Infected needles die and although apical growth slows down, diameter growth appears to be stimulated since the stem becomes thicker and stiffer than normal. Affected seedlings remain in a dormant state until one of the lateral buds on the upper stem develops and grows into a dominant leader. This recovery may occur in the same growing season if the initial infection is very early and there is no reinfection. Under warm, humid conditions the disease can spread very rapidly. Infected seedlings are usually not plantable, resulting in serious economic loss to the nursery.; Host(s): Lupinus angustifolius, L. arboreus, Pinus contorta, P. elliottii, P. muricata, P. nigra subsp. nigra, P. nigra subsp. laricio, P. pinaster, P. ponderosa, P. radiata.

Notes: Identifications based on morphological characters may require molecular re-evaluation. See also Colletotrichum gloeosporioides (p. 128).
Significance: Described as a primary parasite causing a ripe fruit rot and as a saprobe on moribund plant tissue (Dingley & Gilmour 1972). A morphologically indistinguishable forma specialis of this species (Colletotrichum acutatum f.sp. pineum) is pathogenic to pines.; Host(s): Actinidia chinensis, A. deliciosa, A. polygama, Annona cherimola, Cypho-mandra betacea, Feijoa sellowiana, Jasminum mesnyi, Lupinus arboreus, Persea americana, Vaccinium corymbosum.

Notes: The fungus causing blight or anthracnose of lupins has been previously identified in New Zealand as Colletotrichum gloeosporioides, based on morphological characters (Dick 1994). However, molecular analyses (Lardner et al. 1999; Guerber et al. 2003) demonstrated that it belongs within C. acutatum sensu lato. Nirenberg et al. (2002) identified the worldwide lupin anthracnose clade as a separate species, C. lupini.
Significance: This fungus is of major significance to forestry as the cause of lupin blight. The fungus infects lupin plants of all ages and all above-ground parts are susceptible to infection. Infected leaves and petioles wither and much of the foliage is cast. Lenticular lesions develop on branches and stems, particularly at branch axils, and branches often break at the site of infection. Formation of cankers at ground level, leading to death of the whole plant, is common. The fungus also infects developing seed pods which become necrotic. In warm and wet weather, pink conidial masses develop on the pods and on lesions. Until the late 1980s, Lupinus arboreus was a successful secondary coloniser of coastal sand dunes, and was an important component of the planting succession used to establish Pinus radiata forests on mobile sand. It provided shelter for the young trees and its ability to fix atmospheric nitrogen increased the nitrogen status of the ecosystem, thus enhancing tree growth and productivity (Mead & Gadgil 1978). Lupin blight was first noticed in 1988 in Woodhill Forest (Auckland). A survey in early 1989 showed that the disease was present in coastal areas throughout the country, from Spirits Bay in the far north to Masons Bay, Stewart Island. Mortality was estimated to be 90–95% in the North Island and the northern half of the South Island and 60–65% in other parts of the South Island (Dick 1994). Loss of most of the lupins from fixed sand dunes means a substantial reduction in the availability of nitrogen to primary stabilising plants and to the forest crop. There is a risk of reversion to drifting sand and reduction in the productivity of sand dune forests unless fertiliser is applied or other nitrogen-fixing plants able to take the place of L. arboreus in the ecosystem are found (Gadgil et al. 1999). The origin of Colletotrichum lupini is not known. The only other records of Colletotrichum on Lupinus spp. from New Zealand are those of C. acutatum and C. acutatum f.sp. pineum on L. arboreus and C. acutatum f.sp. pineum on L. angustifolius. These fungi are morphologically quite distinct from the lupin blight pathogen. The sudden appearance of the fungus suggests that it was a recent introduction.; Host(s): Lupinus angustifolius, L. arboreus, L. cosentinii, L. pubescens.

Significance: Cyclaneusma minus has been experimentally shown to be able to infect Pinus radiata plants older than 3 years of age over temperatures ranging from 10º to 25ºC (Gadgil 1984). In susceptible trees, infection by the fungus leads to disease, which is characterised by premature casting of 1-year-old or older needles, mainly in spring but also, to a lesser degree, in autumn. Cast needles are usually a mottled yellow brown in colour. Ascomata of C. minus are rarely seen on needles still attached to the tree but are very common on fallen needles. Ascomata production occurs throughout the year but the greatest number of ascomata per unit area is produced during autumn and winter (May–August). Ascospores are forcibly ejected from the ascomata after about 2 hours of rainfall and are wind-dispersed. Airborne ascospores can be trapped throughout the year but are most numerous during autumn and winter months. Current season’s needles are resistant to infection by ascospores until they are 8–9 months old. They become infected in autumn–early winter (May–June), begin to develop yellow brown mottling by July and are usually cast in early spring, when about one year old. At least two morphologically distinct types of C. minus have been found in the New Zealand population but whether these morph-ological differences reflect differences in pathogenicity is unknown (Dick et al. 2001). Aerial surveys of forests throughout New Zealand have shown that the severity of needle-cast was highest in 11–20-year-old stands and lowest in 1–5-year-old and over 25-year-old stands (Bulman 1988). In all districts, microsites, particularly those at high altitudes, had a high incidence of the disease. Trees vary in susceptibility and even in districts where conditions are favourable to infection less than 60% of the trees in a stand usually show symptoms. Trials carried out to explore the relationship between disease severity (expressed as a percentage of the green crown showing symptoms of the disease) and growth have shown that an average disease severity of 60% over six years resulted in a 50% loss in diameter increment (Bulman & van der Pas 2001). Projections of stand growth to age 30 for various proportions of diseased trees predicted a reduction in volume 10–14 m3/ha for each 10% increase in the proportion of diseased trees. For the country as a whole, growth loss of 6.6% per annum for the P. radiata estate aged between 6 and 20 years was predicted. The corresponding financial loss was estimated to be of the order of $51 million per year (Bulman 2001a). Fungicide screening trials have shown that fortnightly applications of dodine or injection with carbendazim were able to control the disease. Two aerial applications of carbendazim a month apart gave no control but monthly aerial applications of dodine for 6 months gave good control. The cost of such measures is not economically justifiable (Hood & Bulman 2001). Silvicultural trials have indicated that stocking density and pruning have no effect on disease incidence or severity. Trials carried out to test the effect of applying different thinning ratios at different crop ages showed that, using susceptibility to the needle-cast as a main criterion for tree selection, a delayed first thinning at age 7 or 8, followed by a second thinning at age 10 succeeded in achieving an almost disease-free final crop stand (Bulman 2001b). Cyclaneusma needle-cast is a disease of complex aetiology and the interactions between host genotype, host nutrition and the variable fungal population are not fully understood. Much work on these aspects remains to be done.; Host(s): Pinus attenuata, P. ×attenuradiata, P. brutia, P. contorta, P. densiflora, P. jeffreyi, P. monticola, P. mugo subsp. mugo, P. mugo subsp. uncinata, P. muricata, P. patula, P. ponderosa, P. radiata, P. strobus, P. sylvestris, P. yunnanensis, Pinus sp.

Notes: Dothistroma septosporum has priority over D. pini because of the earlier publication of the basionym Cytosporina septospora Doroguine. However, the type of C. septospora has been lost and was unavailable when Morelet made the re-combination in Dothistroma. Doroguine’s (1911) description and illustrations are inadequate for reliable identification, casting doubt on the contention that Cytosporina septospora is conspecific with Dothistroma pini. New Zealand collections closely match the type of D. pini.
Significance: Dothistroma needle blight is one of the most serious diseases of Pinus radiata in New Zealand. The major effect of the disease is a reduction in volume increment. This is directly proportional to the degree of crown infection. Van der Pas (1981) found that for an average disease level of 10%, the loss in volume was 9.7%; for a 20% disease level, it was 19.4% and for a 50% disease level, 48.5%. Because of the potential magnitude of growth loss, copper fungicides, which effectively control the disease, have been applied aerially since 1967. Although the disease is kept at a low level by the chemical treatment, growth loss still occurs since tree stands are not sprayed until the infection level reaches 20–25%. New (1989) estimated that the total cost of the disease to the forest industry (including chemical control costs) was $6.1 million per year (1988 dollars). More recent (2003) estimates of the annual cost approach $30 million (L.S.Bulman, New Zealand Forest Research Institute, pers. comm.). Infection process: Conidia produced on the exposed stroma in a mucilaginous matrix are released when the needle surface becomes wet. They are dispersed by water splash, the dispersal distance normally being quite short. Infection in a stand is usually only from neighbour to neighbour and natural transport of conidia over long distances is infrequent. Infected needles attached to the tree are the principal source of inoculum; when needles drop to the forest floor, the stromata are soon overgrown by saprobes and conidial production stops within 2 months (Gadgil 1970). Under favourable conditions (temperature 18 –20–C; needle surface moist), most conidia landing on the surfaces of needles of susceptible hosts germinate within 3 days, the germ tubes continuing to grow on the needle surface and a very few (about 0.1%) forming appressoria over stomatal openings. An infection peg develops between the guard cells and a swollen vesicle forms just below the guard cells (Gadgil 1968). Further hyphal growth occurs in the mesophyll tissues if the needle surface is wet. Lateral spread of hyphae is limited to a few millimetres from the point of infection but a much greater length of the needle is killed through direct and indirect action of a toxic compound, dothistromin (Bassett et al. 1970) produced by the fungus (see below for more details of the effects of dothistromin). Factors governing infection: Three major interacting factors control the infection of a susceptible host by D. pini: temperature, duration of needle wetness, and the number of viable spores landing on the needle surface. Although infection is also dependent on light intensity (Gadgil & Holden 1976), light conditions in the field rarely limit the infection process. Under experimental conditions, production of visible stromata was observed under the four different day/night regimes tested (24 /16/, 20,/12/, 16,/8/ and 12 /4/C) when foliage was kept wet for 8 h or longer after inoculation with a conidial suspension. The optimum temperature regime for infection was 20e/12/C and the severity of infection was greater where the foliage was kept continually moist (Gadgil 1974b). Study of the effect of moisture at 20m/12/C in more detail showed that infection progressed only as far as the formation of a substomatal vesicle when the leaf surface was not kept wet. When the foliage was kept continuously moist, stromata were first observed 19 days after inoculation. The length of a period of dryness after inoculation influenced stromatal development; stromata appeared after 5 days of continuous wetting following a dryness period of 30 days, but took 10 days to develop if continuous wetting followed a dryness period of 60 days (Gadgil 1977). A study by Gilmour (1981) demonstrated the relationship between the effects of temperature, needle wetness and inoculum density on infection in a stand of young Pinus radiata. In 1969–70, when infection levels (and therefore inoculum levels) were low, threshold values for infection were 12eC and a needle wetness period of 20 h. In 1970–71, when the level of infection was noticeably greater, threshold values were 7CC and 10 h. The period between initial infection and the appearance of stromata varied from 6 weeks in December to 15 weeks in May. Progress of the disease: The usual progress of the disease in tree stands of central North Island is as follows: Very little or no infection occurs between May and August because of low temperatures. Many infected needles are shed and soon cease to be a source of inoculum. In September, few infected needles are left in the tree crowns and although new infections occur as temperatures rise, their number is not large. At daily mean temperatures around 12aC, a development period of about 12 weeks elapses before stromata begin to appear on newly infected needles in late November or early December. Conidia produced on these stromata provide the inoculum for the first major infection. Temperatures in early summer are near-optimal for infection and if the weather is wet (as it usually is), there will be a large increase in disease level. Stromata produced from November/December infections appear in February and a second cycle of infection may occur. The main infection period thus extends from late November to the end of February in central North Island; in warmer parts of New Zealand (e.g., Northland) it begins earlier (late October to early November) and in cooler parts (e.g., Southland) it is a little later (December). Chemical control: The main aim of the chemical control programme is to reduce the amount of inoculum available at the beginning of the main infection period by killing as many conidia as possible. Timing of the first (and often the only) treatment is crucial to the success of the spray programme (Gilmour & Noorderhaven 1971). Copper oxychloride, the fungicide usually employed, is very effective; germination of conidia obtained from stromata on needles was 74% before, and 1% after a routine aerial spray application (P.D.Gadgil & L.S.Bulman, unpublished data). Routine aerial spraying to control the disease in Pinus radiata stands has been common practice in New Zealand since 1966. Stands in susceptible age classes (<16 yr) are surveyed from the air in mid-winter, the average percentage of visible crown symptoms being assessed by experienced observers (see van der Pas et al. (1984) for an evaluation of assessment methods used). Tree stands are generally divided into three categories: (i) less than 20% of the crown infected: no spray needed; (ii) 20–40% crown infection: one application in early summer (usually late November–early December); (iii) more than 40% crown infection: two applications, one in early summer and one in late summer (usually mid-February). Details of assessment methods and spray application have been described by Bulman et al. (2004). Genetic diversity: Molecular studies of New Zealand isolates of D. pini showed no evidence of genetic diversity, suggesting that they are derived from a single introduction of one strain of the fungus into the country (Hirst et al. 2000). Dothistromin: Although there is no direct evidence for the involvement of dothistromin in pathogenesis, typical symptoms of the disease were produced when purified dothistromin was injected into needles (Shain & Franich 1981). Plant defence responses to dothistromin-induced damage have been characterised (Franich et al. 1986). The amount of dothistromin produced by different isolates varies, even within New Zealand where only one strain of the fungus exists. Strains from Germany and from central USA have been shown to produce far greater amounts of the toxin than those from New Zealand (Bradshaw et al. 2000). Dothistromin is a difuroanthraquinone having the same tetrahydro-2-hydroxy-bisfuran moiety as that of aflatoxin B1 produced by Aspergillus flavus (Gallagher & Hodges 1972). This particular structural feature of aflatoxin B1 is considered to be responsible for its hepatotoxicity and potential human carcinogenicity. Elliott et al. (1989) explored the possibility that dothistromin may be carcinogenic and thus pose a risk to forest workers. The amounts of dothistromin found in the forest environment (a maximum of 7 ng/ml in ponds and streams and lower concentrations in air and run-off from trees) were considerably lower than the minimum dose of aflatoxin (50 ng/kg body weight/day) needed to produce cancer in animals. They concluded that dothi-stromin was not a human health risk.; Host(s): Very slightly susceptible: Pinus ayacahuite, P. coulteri, P. devoniana, P. montezumae, P. patula, P. pseudostrobus, P. sabineana, P. serotina, P. strobus, P. sylvestris, P. taeda, P. torreyana.

Distribution: Northland, Waikato, Bay of Plenty, Taranaki, Wanganui, Wellington.; 1st Record: Ridley (2001a).
Notes: Identification of this fungus has been based on cultural characters. Rossman et al. (1999) reported that the Fusarium anamorphs of two New Zealand species of Cosmospora (C. dingleyae Lowen and C. obscura Lowen) are characterised by cultures similar to those of F. merismoides. A comparison of New Zealand Forest Research Institute cultures with published descriptions of the two Cosmospora species indicates several apparent but not necessarily conclusive differences. The identi-fication of F. merismoides must therefore be held to be tentative.
Significance: Associated with dieback of twigs. Pathogenicity tests have shown that it is a weak wound pathogen of Podocarpus totara (Ridley 2001a).; Host(s): Acmena smithii, Corokia cotoneaster, Cotoneaster sp., Hoheria sp., Paulownia tomentosa, Podocarpus totara, Prumnopitys ferruginea, Sorbus aucuparia.
Type: Radicicolous Fungi; Description: Colonies on agar with white or peach aerial mycelium, usually tinged purple or violet, floccose, becoming felty.

Distribution: Northland, Auckland, Waikato, Bay of Plenty, Taranaki, Taupo, Wanganui, Wellington, Gisborne, Hawkes Bay, Wairarapa, Nelson, Buller, Marlborough, North Canterbury, Mid Canterbury.; 1st Record: Kirk (1905).
Notes: Fusarium oxysporum has a large number of formae speciales or pathotypes, based on host specificity, which are morphologically indistinguishable. The host list below does not include hosts of these formae speciales.
Significance: Fusarium oxysporum is the most common species of Fusarium isolated from nursery soils (Dick & Dobbie 2002). It is associated with damping off and root rot of seedlings in coniferous nurseries.; Host(s): Pinus radiata, Pseudotsuga menziesii.
Type: Radicicolous Fungi; Description: Colonies on agar with dense, white vinaceous, floccose to felty aerial mycelium. Chlamydospores none. Microconidia fusiform to clavate, 0-septate, 5–12 × 1.5–2.5 μm, catenate. Macroconidia fusoid, 3–7-septate, 25–60 × 3–4 μm, with a sharply curved apical cell and a well-developed foot cell.
Distribution: Northland, Bay of Plenty, Hawkes Bay.; 1st Record: Laundon (1978a: as Gibberella fujikuroi).
Notes: There is considerable confusion about the synonymy of the New Zealand material described as Fusarium moniliforme. In the broad sense of Wollenweber & Reinking, this name covers not only Fusarium verticilloides but also F. proliferatum var. proliferatum and F. proliferatum var. minus. All these are without known teleomorphs and none are connected with Gibberella fujikuroi sensu stricto. In the absence of definitive work on the New Zealand material, the compromise solution is to record it as Fusarium proliferatum.
Significance: Occasionally recorded from forest nurseries (Dick & Dobbie 2002).; Host(s): Dracaena fragrans, Pinus radiata.
Type: Radicicolous Fungi; Description: Colonies on agar with white to greyish white aerial mycelium, floccose. Chlamydospores none. Microconidia oval to obclavate, 0-septate, 8–12 × 2–3 μm, hyaline. Macroconidia falcate, 3–5-septate, 32–53 × 3–5 μm, hyaline.
Distribution: Auckland, Wanganui, Hawkes Bay.; 1st Record: Neil & Brien (1935: as Fusarium moniliforme var. subglutinans).
Notes: Fusarium subglutinans has been placed in synonymy under earlier names and its application to New Zealand material is confused. According to Gerlach & Nirenberg (1982), the basionym Fusarium moniliforme var. subglutinans includes F. sacchari var. sacchari and F. sacchari var. subglutinans. In the absence of definitive work on the New Zealand material, the compromise solution is to record it as Fusarium sacchari.
Significance: None. Occasionally recorded from forest nurseries (Dick & Dobbie 2002). Molecular techniques have established that the New Zealand isolates do not belong to the morphologically indistinguishable forma specialis Fusarium subglutinans f.sp. pini Correll et al. (K.Dobbie, New Zealand Forest Research Institute, pers. comm.), which is the causal agent of pine pitch canker, a major disease of Pinus spp., especially P. radiata.; Host(s): Pinus radiata.

Pore surface even or sometimes distinctly pitted, at times even and pitted in different parts of the same fruit body, sterile margin 1–3 mm wide, concolorous with pore surface, white to pale yellow to light pink, brown when tubes not actively growing, pores in obvious strata and often with a thin (approximately 1 mm) band of context tissue separating the strata, 4–5 per mm. Context azonate or weakly zonate, dark reddish brown, up to 40 mm thick. Hyphal system trimitic. Basidiospores ovoid, 9–11 × 6–8 μm, punctate, appearing verruculose, pale brown.
Distribution: Northland, Auckland, Coromandel, Waikato, Bay of Plenty, Taranaki, Taupo, Wanganui, Wellington, Gisborne, Hawkes Bay, Wairarapa, Nelson, Buller, Westland, Fiordland, Marlborough, Mid Canterbury, Otago Lakes, Central Otago, Dunedin, Stewart Island, Chatham Islands.; 1st Record: Berkeley (1855: as Polyporus igniarius).
Significance: One of the commonest perennial bracket fungi in exotic and indigenous forests. Causes a white heart rot in indigenous trees and may attack the sapwood when the heartwood is completely rotted. In exotic conifers it is rarely associated with heart rot and has no economic significance.; Host(s): Acacia dealbata, A. melanoxylon, Agathis australis, Beilschmiedia tarairi, Fuchsia excorticata, Metrosideros robusta, Nothofagus fusca, N. menziesii, N. solandri var. solandri, N. truncata, Pinus radiata, Populus spp., Prumnopitys ferruginea, Quercus robur, Weinmannia racemosa.
Type: Lignicolous Fungi; Description: Basidiomata perennial, solitary, hard, woody, attached by a broad lateral base. Pilei applanate, 70–300 mm wide, 30–130 mm thick. Pileus surface concentrically sulcate, sometimes weakly radially ridged or warty, grey, frequently brown with a dusting of spores, margin rounded, cream, 2–7 mm wide. Pore surface even or slightly pitted, with a cream sterile margin 1–7 mm wide, white to light grey, sometimes with large areas tinted orange, pores indistinctly stratose, 3–5 per mm. Context weakly zonate, dark brown. Hyphal system trimitic. Basidiospores ovoid, 11–14 × 7–9 μm, punctate, appearing verruculose, pale brown.
Distribution: Northland, Auckland, Waikato, Bay of Plenty, Taranaki, Taupo, Wellington, Nelson, Buller, Westland, Marlborough, North Canterbury, Mid Canterbury, Otago Lakes, Central Otago, Dunedin.; 1st Record: Berkeley (1855: as Polyporus australis).

Asci clavate, 84–120 × 16–20 1m. Ascospores oval to broadly elliptical, 1–3-septate, 24–33 × 8–11 8m, smooth, hyaline or light brown. Macroconidia cylindrical, 1–5-septate, 32–80 × 5–8 5m, smooth, hyaline, with sharply-curved ends. Microconidia oval, 0-septate, 2–4 × 1–2 1m, smooth, hyaline.
Distribution: Auckland, Coromandel, Taranaki, Taupo, Wellington, Nelson.; 1st Record: Sydow (1924: as Botryosphaeria macrolopha).
Significance: The presence of this fungus on cankers on living branches suggests that it is pathogenic.; Host(s): Coprosma foetidissima, C. grandifolia, C. robusta, C. tenuifolia.
Type: Caulicolous Fungi; Description: Basidiomata perennial, effused, forming irregular patches 60–100 × 30–40 mm.

Metuloids abundant, gloeocystidia present. Cystidia encrusted, 30–45 × 7–10 μm, hyaline. Basidiospores subglobose to ellipsoid, 6–9 × 6–7 μm, echinulate, amyloid.
Distribution: Northland, Auckland, Bay of Plenty, Taranaki, Taupo, Rangitikei, Wanganui, Wellington, Wairarapa, Buller, Westland, Marlborough, Dunedin.; 1st Record: Cunningham (1955).
Significance: Causes root rot and stem canker that results in group mortality over restricted areas. It is often already established in small areas of indigenous scrub vegetation (mainly Leptospermum scoparium) present before exotic trees are planted. Infection of planted trees occurs when a root or part of the stem comes in contact with infected roots or twigs of the scrub plants. Leptospermum scoparium, Pteridium esculentum, and Rubus fruticosus often act in this way as transmission agents. As the disease progresses a girdling canker develops at the root collar or on the stem, and copious resin bleeding occurs. Infected trees die slowly over a period of 3–4 years and roughly circular patches of dead vegetation are a distinctive feature of the disease. In most parts of New Zealand, incidence of the disease is low and losses are insignificant. In three Northland forests and one forest in Marlborough where the fungus is widespread, 10–20% mortality was reported within 10 years of establishment (Dick 1983).; Host(s): Parasitic attack: Brachyglottis repanda, Chamaecyparis lawsoniana, Coprosma grandifolia, Cupressus macrocarpa, Cytisus scoparius, Dendrobenthamia capitata, Eucalyptus botryoides, E. ovata, E. saligna, Hakea sericea, Hebe sp., Leptospermum scoparium, Macropiper excelsum, Pinus caribaea, P. contorta, P. elliottii, P. muricata, P. nigra subsp. laricio, P. palustris, P. patula, P. pinaster, P. radiata, P. taeda, Podocarpus totara, Pomaderris kumeraho, P. phylicifolia, Prumnopitys ferruginea, Prunus armeniaca, P. avium, P. cerasifera, P. persica, Pseudopanax arboreus, Pseudotsuga menziesii, Pyrus communis, Rosa rubiginosa, Thuja plicata, Ulex europaeus.

Type: Foliicolous Fungi; Description: Conidiomata acervular, solitary or aggregated, subepidermal, dark brown; on roughly circular leaf spots with brownish margins and grey-white centres, 5–15 mm in diameter, on upper surfaces of leaves. Conidia oblong, 0-septate, 16–18 × 4–6 μm, smooth, hyaline.
Distribution: North Canterbury.; 1st Record: Sydow (1924).
Significance: None.; Host(s): Coprosma serrulata.
Type: Caulicolous Fungi; Description: Ascomata perithecial, scattered or aggregated in groups, immersed, globose, dark brown, 0.1–0.3 mm in diameter, ostiolate; on cankers on living stems and overwintering on fallen leaves. Asci clavate, 45–65 × 8–128m. Ascospores oval to elliptical, 0-septate, 10–16 × 3–6 3m, smooth, hyaline. Conidiomata acervular, immersed, finally partly erumpent, rupturing the epidermis, on necrotic lesions on leaves. Conidia cylindrical to elliptical, 0-septate, 13–25 × 3–7 3m, smooth, hyaline. Only the teleomorph is present on cankered stem tissue and only the anamorph is found on living leaves.
Distribution: Auckland, Bay of Plenty, Taranaki, Wanganui, Wellington.; 1st Record: Spiers & Hopcroft (1993). Earlier records (as Physalospora miyabeana) by Gilmour (1966a) and Dingley (1969) are based on the opinion of both authors that Gnomonia bullata reported on willow by Murray (1926a) was synonymous with Physalospora miyabeana. Spiers & Hopcroft (1993) have pointed out that this synonymy cannot be sustained as the two fungi are quite distinct.
Significance: This fungus is unusual because it causes stem canker but not leaf spotting in some backcross Salix matsudana × alba cultivars; leaf spotting and defoliation but not stem canker in other Salix species and cultivars. Stem cankering in susceptible cultivars leads to death within two years. Leaf spotting does not cause serious damage and the fungus is not considered to be a serious pathogen in New Zealand (Spiers & Hopcroft 1993).; Host(s): on stems: Salix (matsudana × alba) × alba; on leaves: Salix amygdaloides, S. daphnoides, S. gooddingii, S. lasiolepis.
Type: Foliicolous Fungi; Description: Ascomata perithecial, in small clusters united by a rudimentary stroma, subepidermal, immersed, dark brown, ostiolate, with a short neck 12–30 μm long; on necrotic spots on the upper surfaces of leaves.

Significance: The principal cause of heart rot in living Podocarpus totara which, due to the normal durability of its wood, was once a very important timber tree. The yellow-pipe rot is characterised by long, narrow, parallel, pale yellow tubular cavities. Affected wood is suitable for fencing material but useless for dressing grades. The rot is known to bushmen as ‘kaikok’, a corruption of ‘kaikaka’ which is the Māori word for totara heartwood (Williams 1971). Although common in P. totara, it is rare in Nothofagus fusca and N. truncata.; Host(s): Nothofagus fusca, N. truncata, Podocarpus hallii, P. totara.

Significance: The cause of low-level mortality (about 1%) in Pinus radiata plantations in the Bay of Plenty, predominantly on sites previously covered by indigenous forest (Hood & Dick 1988). The fungus is associated with root disease in other coniferous hosts and has been isolated from orchard shelterbelt trees suffering from ‘white crown canker’. It has been shown to be pathogenic to seedlings of Chamaecyparis lawsoniana, Cryptomeria japonica, Cupressus macrocarpa, Eucalyptus regnans, Pinus radiata, Salix matsudana, and Thuja plicata (Hood & Dick 1988).; Host(s): Parasitic attack: Berberis glaucocarpa, Chamaecyparis lawsoniana, Cryptomeria japonica, Cupressus macrocarpa, Eucalyptus regnans, Pinus radiata, Salix matsudana, Thuja plicata.

Distribution: Mid Canterbury, South Canterbury.; 1st Record: Gadgil & Dick (2001).
Significance: Associated with dieback of tips of leaves, which is more severe in the lower part of the crown. Although it has been recorded as the cause of shoot dieback of Thuja occidentalis in Europe (Schneider & Arx 1966), and tip blight and canker of Chamaecyparis nootkatensis in Canada (Funk 1981), it is not regarded as a major pathogen.; Host(s): Chamaecyparis lawsoniana, Thuja plicata.

Notes: The correct name for this very common fungus is in some doubt. It was first recorded in New Zealand by Colenso (1893) as Agaricus (Clitocybe) laccatus. This name was based on a specimen collected near Dannevirke and sent to Cooke for identification. Massee (1899) later included it in his account of the fungus flora of New Zealand as Laccaria laccata. The specimen on which these records were based is no longer extant. Stevenson (1964) noted that L. laccata was the commonest toadstool in the country. McNabb (1972) failed to find L. laccata during the course of his study of Laccaria and remarked that all Stevenson’s collections examined by him could be referred to either L. proxima or L. tetraspora. The description that follows is of the variable species usually referred to as Laccaria laccata, which is very common in nurseries and plantations of Pinus radiata.
Significance: A very common and variable fungus with fruiting bodies occurring in troops in nurseries and plantations. Isolated from and experimentally shown to be a mycorrhizal partner of Pinus radiata (Chu-Chou 1979), Pseudotsuga menziesii (Chu-Chou & Grace 1981c) and Eucalyptus delegatensis (Chu-Chou & Grace 1982). In a comparative study it was found that seedlings inoculated with L. laccata grew better than seedlings inoculated with Rhizopogon rubescens during the first six months. The increased growth rate was not maintained and the R. rubescens-inoculated seedlings were larger by the end of the growing season (Chu-Chou & Grace 1985).; Host(s): Betula pendula, Eucalyptus delegatensis, Pinus nigra subsp. laricio, P. radiata, Pseudotsuga menziesii.
Type: Corticolous Fungi; Description: Ascomata apothecial, scattered, superficial, stalked, covered with long white hairs, disc orange, up to 3 mm in diameter; on bark. Asci cylindric-clavate, 100–150 × 8–10 μm. Ascospores elliptic oblong, 0-septate, 14–20 × 6–8 μm, smooth, hyaline.
Distribution: Bay of Plenty, Taupo, North Canterbury, Southland.; 1st Record: Gadgil & Dick (2000a).
Significance: Dennis (1978) regarded this species as a harmless saprobe.

Significance: Species of Leptographium have been associated with death of individual Pinus radiata and P. strobus trees in many parts of New Zealand (Shaw & Dick 1980; MacKenzie & Dick 1984). Infected trees show a black stain in the roots and in sapwood at the base of the tree. Resin bleeding at the base is common in P. radiata. Infected trees usually die quickly but some persist for up to 8 years with thin chlorotic crowns. Infection has been recorded only in forests on heavy clay soils prone to waterlogging. Many tree stands containing infected trees were grazed by cattle that damage surface roots and compact the soil. Stress caused by waterlogging and root disturbance appears to be main factor leading to death of infected trees. Species of Leptographium known to be present in New Zealand (L. alethinum, L. euphyes, L. lundbergii, and L. procerum) were found to be mildly pathogenic to P. radiata and P. strobus. Pinus strobus was more susceptible to infection than P. radiata and waterlogging made plants of both species more susceptible (M.A.Dick, unpublished data).; Host(s): Pinus radiata, P. strobus.

Significance: Johnston (1992) recorded 24 species of Lophodermium in New Zealand, mostly on fallen leaves. Only two of these and the recently reported L. molitoris (Johnston et al. 2003) are known from living leaves. For descriptions of the other species, see Johnston (1989). Before the appearance of Minter’s (1981) monograph on species of Lophodermium on pines, the three species now known to be present on Pinus spp. in New Zealand were collectively called Lophodermium pinastri. In association with Cyclaneusma minus, they were considered to be responsible for a periodic needle-cast of Pinus radiata (Gilmour 1966a). It has since been shown that this needle-cast is attributable to C. minus alone. Species of Lophodermium present in New Zealand are regarded as saprobes although they are endophytic in needles of P. radiata (Gadgil 1984). In New Zealand, L. conigenum and L. pinastri are both common in pine plantations; L. molitoris is known from a single collection. The only major pathogenic species, Lophodermium seditiosum Minter, Staley & Millar (Minter & Millar 1980) is not present in New Zealand.; Host(s): Pinus contorta, P. radiata.

(1974).
Significance: This fungus was first detected in 1973 and spread rapidly, causing considerable damage in the moist areas of New Zealand. Infection leads to early defoliation, which, if repeated, reduces height and diameter growth and delays hardening-off. Shoots become more prone to frost damage and, in highly susceptible varieties (P. nigra ‘Sempervirens’, for example) there is dieback and death. Introduction of rust-resistant varieties has reduced adverse effects considerably. Natural infection of conifers is very rare. An interspecific hybrid between M. larici-populina and M. medusae has been described (Spiers & Hopcroft 1994).; Host(s): Spermagonia and aecia on Larix decidua, L. kaempferi, Pinus radiata. Uredinia and telia on Populus ×canadensis, P. deltoides, P. deltoides var. missouriensis, P. ×generosa, P. ×gileadensis, P. maximowiczii × berolinensis, P. maximowiczii × nigra, P. maximowiczii × trichocarpa, P. nigra, P. trichocarpa, P. yunnanensis.
Type: Rust and Smut Fungi; Description: Spermagonia solitary to aggregated in small groups, circular to lenticular, pale yellow, up to 0.2 mm in diameter, surrounded by a halo of yellow tissue; on needles. Aecia aggregated in groups of two to four, irregularly oval, yellow-orange, 0.5–1 mm in diameter; on yellow spots on needles. Uredinia single or aggregated in groups, circular, bright orange-yellow, 0.5–1 mm in diameter; on both sides of leaves. Urediniospores obovate to oval, apex rounded, base truncate, 22–35 × 15–25 μm, uniformly echinulate except for a smooth equatorial area commonly extending half to three-quarters around the spore. Telia occasionally single but more often aggregated in groups which coalesce, circular, amber brown to dark brown, up to 1 mm in diameter; on both sides of leaves. Teliospores cylindrical to triangular, 20–50 × 6–16 μm, pale.
Distribution: Northland, Auckland, Coromandel, Waikato, Bay of Plenty, Taupo, Gisborne.; 1st Record: Anonymous (1973); van Kraayenoord et al. (1974).
Significance: M. larici-populina and M. medusae were first recorded in New Zealand in 1973. M. medusae was associated with M. larici-populina in the early outbreaks, but appeared to be restricted to isolated trees of Populus deltoides. By 1984, M. medusae had apparently died out but it has been occasionally recorded since then (Spiers 1998). It is not possible to distinguish damage caused by M. medusae from that caused by M. larici-populina in the field. An interspecific hybrid between M. larici-populina and M. medusae has been described (Spiers & Hopcroft 1994).; Host(s): Spermagonia and aecia on Larix decidua. Uredinia and telia on Populus ×canadensis, P. deltoides, P. deltoides var. missouriensis, P. maximowiczii × berolinensis, P. maximowiczii × nigra, P. maximowiczii × trichocarpa, P. simonii, P. yunnanensis.

Distribution: Wanganui.; 1st Record: Gadgil & Dick (2000a).
Significance: Funk (1985) reported that this fungus causes a rare needle-blight of Pinus monticola in Canada. It is regarded as a weak parasite of Pinus spp. in Europe (Smith et al. 1988). In China, however, it has been shown to be a serious pathogen of P. massoniana (Hu 1983). In New Zealand, it has been found fruiting on the dead tips of needles and is regarded as a minor pathogen of P. strobus.; Host(s): Pinus strobus.
Type: Foliicolous Fungi; Description: Mycelium internal, substomatal. Conidiophores emerging from stomata in dense tufts, simple or branched, frequently curved, hyaline, up to 45 μm long. Conidia cylindrical with a median constriction, 0-septate, 9–13 × 3–4 μm, smooth, hyaline. Leaf spots absent. The fungus is very difficult to see on the needles unless stained with aniline blue.
Distribution: Waikato, Bay of Plenty, Taupo, Rangitikei, Wellington, Hawkes Bay, Nelson, Westland, Marlborough, Kaikoura, North Canterbury, Mid Canterbury, South Canterbury, Dunedin, Southland.; 1st Record: Weston (1957).
Significance: The cause of premature needle cast in larch. Infected needles turn yellow, then red brown and are cast, usually in midsummer. Nursery seedlings and young plantations of Larix decidua are highly susceptible; L. kaempferi is regarded as relatively resistant. The disease is of minor significance.; Host(s): Larix decidua, L. kaempferi.
Type: Mycorrhizal Fungi; Description: Basidiomata hypogeous, globose, subglobose or lobed, concolorous with the substrate, 10–40 mm in diameter; peridium composed of three layers: the exoperidium comprising a complete case formed from particles of the surrounding substrate (e.g., sand, soil, or litter) tightly bound into a hard, black layer by pigmented hyphae; the mesoperidium consisting of a network of the tree rootlets embedded in hyaline hyphae; and the endoperidium forming a creamy white layer not penetrated by rootlets from the mesoperidium. Gleba olivaceous to smoky grey, powdery at maturity; capillitium threads hyaline, unbranched; core concolorous with the endoperidium, occupying about half of the glebal cavity; attached by a few widely spaced, flattened tuberculae about 2 mm thick. Basidiospores elliptical, 0-septate, 8–13 × 4–6 μm, mostly smooth but occasionally finely warted, hyaline but faintly tinted in mass, with or without a short pedicel.
Distribution: Coromandel, Waikato, Bay of Plenty, Taupo.
Significance: The intimate and invariable association of mature fruiting bodies with tree roots and the presence of a partial Hartig net are indications that M. glauca is an obligate ectomycorrhizal fungus (Beaton & Weste 1983). No investigation of its mycorrhizal relationships has been carried out in New Zealand. Fruiting bodies develop underground to a depth of 30 cm or more and are exposed by animals that dig them up. Wild pigs seem to be particularly attracted to Mesophellia. In Eucalyptus plantations on pumice soils in the central North Island, large areas resembling ploughed fields are occasionally seen where pigs have been rooting for the fruiting bodies.

Significance: Oak powdery mildew can be very damaging to nursery stock, coppice shoots, and young leaves, particularly in Quercus robur. The fungus attacks young leaves and occasionally young shoots in spring. Leaves soon become covered with a layer of white mycelium and powdery masses of conidia. In severe attacks, the leaves shrivel, turn brown, and fall. The disease is confined to young leaves. It is not important on older trees but may kill young seedlings in the nursery.; Host(s): Ailanthus altissima, Castanea crenata, C. sativa, Cotinus coggygria, Platanus ×acerifolia, P. orientalis, Quercus faginea, Q. petraea, Q. robur.

Significance: The fungus can have a marked effect on growth and form of young trees, particularly in damp places such as gullies. Premature defoliation, cankering and dieback of shoots result in stunting, multileadering and the development of a bushy habit. Provenances of E. regnans show variability in susceptibility to infection (Wilcox 1982) and planting of resistant provenances can reduce the effects of the disease. In forest nurseries, fortnightly applications of fungicide have been found to give good control (Dick & Vanner 1986).; Host(s): Eucalyptus dalrympleana, E. delegatensis, E. dendromorpha, E. fastigata, E. fraxinoides, E. gunnii, E. nitens, E. obliqua, E. ovata, E. regnans.

Distribution: Waikato, Bay of Plenty, Taranaki, Taupo, Wellington, Hawkes Bay, Nelson, Mid Canterbury, Central Otago, Otago Lakes, Dunedin, Southland.; 1st Record: Kirk (1905).
Significance: This very common fungus is a wound parasite causing a disease of fruit trees known as ‘coral spot’, from the bright coral red colour of conidial masses. It usually becomes established in dead branch stubs and invades uninjured tissue, causing branch dieback (Atkinson 1971). It is of minor importance. In forestry the fungus has been found on Pinus radiata seedlings damaged by insects or by cattle, but it generally causes little mortality. It has been frequently reported on broom, a common weed in young tree plantations.; Host(s): Abutilon sp., Acer sp., Aesculus hippocastanum, Betula pendula, Cytisus scoparius, Juglans regia, Laburnum sp., Malus ×domestica, Morus nigra, Pinus radiata, Prunus armeniaca, P. avium, P. ×domestica, P. dulcis, P. persica, P. persica var. nucipersica, Pyrus communis, Quercus robur, Ribes nigrum, R. rubrum, R. sanguineum, Rosa sp., Sophora microphylla, Ulmus sp.

Distribution: Dunedin, Southland.; 1st Record: Gadgil et al. (2003).
Notes: Nectria fuckeliana is one of three similar species of nectriaceous fungi recorded on conifers. The other two, N. pinea (see p. 152, under Neonectria discophora var. discophora) and N. neomacrospora have both been transferred to the genus Neonectria (Mantiri et al. 2001), on the basis of molecular analyses and their production of Cylindrocarpon macroconidia. Brayford et al. (2004) found that Nectria fuckeliana cultures produced only microconidia and no Cylindrocarpon macroconidia, and were separate from the monophyletic Neonectria clade in molecular analyses; on this basis, they retained N. fuckeliana in Nectria sensu stricto. Gadgil et al. (2003), working with New Zealand isolates identified as Nectria fuckeliana, have reported that Cylindrocarpon macroconidia formed readily in paired cultures on sterilised pine twigs.
Significance: Frequently reported as an invader of wounds, mainly in Picea spp. in Europe (Roll-Hansen & Roll-Hansen 1980; Vasiliauskas & Stenlid 1998) and North America (Smerlis 1969; Ouellette 1972). In New Zealand, it has been consistently found on pruning wounds associated with long cankers extending several metres up into the green crown and almost to the base of the tree (M.Dick, New Zealand Forest Research Institute, pers. comm.). Affected stems are easily recognisable as they become fluted. The trees usually survive but growth slows and they become prone to wind breakage. Damage associated with the fungus is restricted to small groups of trees within a stand. The problem was recognised only recently and no economic evaluation of its effect is available.; Host(s): Pinus radiata.
Type: Corticolous Fungi; Description: Ascomata stromatic, perithecial, solitary or aggregated in clusters of a few, or densely gregarious, globose, cream becoming yellow orange later, hairy, 0.2–0.3 mm in diameter, ostiole non-papillate, superficial, on a thin, white, flat subiculum; on stipes of tree ferns or on bark of Leptospermum.

Distribution: Auckland (metropolitan region only), Hawkes Bay (Napier; sub-sequently eradicated).; 1st Record: Bain (1991).
Notes: Two major forms or races of O. novo-ulmi known as EAN (Eurasian) and NAN (North American) have been recognised (Brasier 1979). The New Zealand population of O. novo-ulmi is considered to belong to a single clone of the NAN European Vegetative Compatibility Supergroup (C.Brasier, Alice Holt Research Station, Surrey, UK, pers. comm.). Ophiostoma novo-ulmi is transmitted by scolytid bark beetles. In New Zealand, the only vector present is the small elm bark beetle, Scolytus multistriatus Marsham. The fungal anamorphs sporulate in tunnels made by the beetle and conidia are accidentally picked up by emerging adults. Ophiostoma novo-ulmi is heterothallic with two compatibility types, A and B. New Zealand isolates belong to the B-type. Ascomata were obtained only when conidia from A-type cultures imported from England were brushed on to the surface of the New Zealand cultures.
Significance: The cause of ‘Dutch elm disease’ which has been responsible for the death of most of the elms in Europe and North America (Brasier 2000). In New Zealand it was first detected in Myers Park, central Auckland, in December 1989. A delimiting survey showed that the disease was present in an area approximately 8 × 5 km in the Auckland metropolitan area and an eradication campaign was started immediately. The number of infected elms detected was relatively high at first (83 in 1989–90; an average of 20 per year between 1990–91 and 1994–95). From 1995–96 to 1998–99, only one or two infected trees were found and destroyed each year. Disestablishment of the Ministry of Forestry, which had been responsible for the eradication campaign up to 1998–99, was accompanied by a reduction in the intensity of the campaign. The number of infected trees has increased (11 were found in 2002–2003) and the success of the campaign, which seemed reasonably certain in 1998–99, is now in doubt. If the disease is allowed to spread, the entire New Zealand elm population is under threat. Although beetles carrying O. novo-ulmi have been found only in the metropolitan Auckland region, Scolytus multistriatus without the pathogen is currently (2005) found in an area between Warkworth to the north, Te Awamutu to the south, and Matamata and Te Aroha to the east. The distribution of the beetle appears to be expanding and there is no reason why it should not eventually reach all areas that have a population of elms. In 1993, a group of four trees in Sturm’s Gully reserve, Napier, was found to be infected with O. novo-ulmi. Isolates of the fungus were identical with those from Auckland trees. Intensive trapping using aggregating pheromones for S. multistriatus and S. scolytus failed to capture any Scolytus species and no signs of beetle activity were detected. In the absence of a vector, the disease remained confined to the gully, but continued to spread through root grafts. In view of the south-eastward progression of S. multistriatus, absence of the vector could not be guaranteed, and so all elms in the reserve were destroyed. The disease has not reappeared in Napier. It is not known how the fungus reached Napier in the absence of a vector.; Host(s): Ulmus americana, U. ×hollandica, U. ×vegeta, Ulmus sp. (Chinese species, e.g., Ulmus parvifolia and U. pumila, are resistant to infection.)

Significance: The cause of ‘Swiss needle-cast’, a major disease of Douglas fir in New Zealand. It was first recorded in 1959 when present only in a limited area around Taupo. Its progress was carefully observed and it took about 30 years for the fungus to spread throughout the country (Hood et al. 1990). Analysis of data from 1500 permanent sample plots showed that the reduction in volume increment following the appearance of the disease was: Central North Island 21%; Nelson 9%; Canterbury 20%; Otago 23% (Knowles et al. 2001). Hood (1982) showed that levels of infection in provenances of Pseudotsuga menziesii originating west of the Coast-Cascade Mountains in British Columbia, Washington and Oregon were significantly lower than in provenances originating in the area between the Coast Range and the eastern mountains. Future planting of selected resistant trees and provenances is expected to reduce the effect of the disease.; Host(s): Pseudotsuga macrocarpa, P. menziesii.
Type: Lignicolous Fungi; Description: No published description of New Zealand material of Phaeolus schweinitzii sensu stricto is available. The following description has been adapted from Ryvarden (1978). Basidiomata annual, compound, composed of several pilei arising from a common base, soft and fleshy when fresh, brittle when dry. Pilei fan-shaped up to 200 mm in diameter. Pileus surface tomentose to hirsute, first bright yellowish, later deep golden to reddish brown, margin usually distinctly lighter than the rest of the pileus. Pore surface yellowish at first, rusty brown later; pores large, angular, 0.3–1 per mm. Context golden to rusty brown, up to 10 mm thick. Hyphal system monomitic. Cystidia numerous, club-shaped to conical, 30–150 × 6–20 mm, hyaline to distinctly dark brown, often projecting up to 50 μm above the hymenium. Basidiospores ellipsoid, 0-septate, 5–8 × 3–5 μm, smooth, hyaline.
Distribution: Auckland, Dunedin, Southland.; 1st Record: Buchanan & Ryvarden (2000); Buchanan (2003).
Significance: Phaeolus schweinitzii is a common cause of butt rot in mature trees in boreal coniferous forests, lessening the value of the butt log and making trees prone to windthrow. As young trees are very rarely attacked, it is unlikely that the fungus will pose a threat to short-rotation plantation forests.; Host(s): Pinus radiata.

Pileus surface tomentose, concentrically sulcate, rusty brown to chocolate brown, margin even or crenate. Pore surface even, with a sterile border 2–10 mm wide, chestnut brown; pores large, angular, 1–3 per mm. Context chestnut brown, 3–7 mm thick. Hyphal system monomitic. Basidiospores broadly elliptical to subglobose, 5–8 × 4–5 μm, smooth, hyaline.
Distribution: Northland, Auckland.; 1st Record: Cunningham (1948c: as Coltricia schweinitzii).

Significance: Associated in the late 1950s with mortality of 20-year-old or older conifers in farm shelterbelts growing on heavy clay soils, after prolonged periods of waterlogging (Newhook 1959). No damage to trees growing in plantations has been found. The fungus is associated with rootlet rot in young seedlings of some important plantation trees (Chamaecyparis lawsoniana, Cupressus macrocarpa, Pinus radiata) (Newhook 1959).; Host(s): Actinidia deliciosa, Chamaecyparis lawsoniana, Cupressus macrocarpa, Cyphomandra betacea, Feijoa sellowiana, Hebe odora, Malus ×domestica, Meryta sinclairii, Myoporum parvifolium, Phebalium squameum, Pinus radiata, Pyrus communis, Rhododendron sp., Ribes uva-crispa var. sativum, Rubus idaeus.

Significance: Most species of Phytophthora recorded as being associated with trees and shrubs in New Zealand are soil-borne and infect roots and the lower stem. These two species are unusual in that they are found in dying leaves in the crowns of eucalypt trees at a height of up to 20 m. Locally severe crown dieback associated with foliage, shoot, and twig infection by these two Phytophthora species has been recorded in E. botryoides and E. saligna in the Bay of Plenty and in E. delegatensis in Southland. The occurrence is episodic and infection appears to take place during the winter months. Infected leaves are readily abscised, defoliation and twig infection leading to dieback of the crown. The fungi can be isolated from soil beneath infected trees but as the sporangia of neither species are deciduous, it is not known how the fungi reach foliage high in the tree crown. Pathogenicity of Phytophthora ‘captiosa’ to E. botryoides, E. regnans, and E. saligna has been established in laboratory tests.; Host(s): Eucalyptus botryoides, E. saligna.

Significance: The significance of P. cinnamomi in the New Zealand forest industry has been the subject of vigorous and occasionally acrimonious debate in the past. It is agreed that the fungus is an important pathogen of tree seedlings in nurseries established on heavy clay soils prone to waterlogging. In such nurseries, severe root-rot of seedlings of Acacia baileyana, A. verticillata, Betula verrucosa, Eucalyptus ficifolia, Metrosideros excelsa, and Pinus radiata has been attributed to P. cinnamomi (Gilmour 1966a). Bassett (1961) reported that P. cinnamomi was associated with root-rot and collar canker of 2-year-old seedlings of Larix decidua and Pseudotsuga menziesii. The status of the fungus as a pathogen of older (>3-year-old) trees in New Zealand is not clear. Phytophthora cinnamomi has been recovered from soil beneath many exotic and indigenous plant communities throughout New Zealand. With one exception, none of these communities showed symptoms of ill health attributable to infection by the fungus (Newhook & Podger 1972). The exception involved certain farm shelterbelts in which episodic mortality was associated with P. cinnamomi. In 1953–54 and 1955–56, sudden death of 20-year-old and older trees of Chamaecyparis lawsoniana, Cupressus macrocarpa, and Pinus radiata occurred in farm shelterbelts growing on heavy clay soils in the Northland region (Newhook 1959). There had been droughts during the previous summers, followed by abnormally wet periods in autumn, winter, and spring (Sutherland et al. 1959). Mortality under similar climatic and edaphic conditions was reported from Hawkes Bay in the 1970s (New Zealand Forest Research Institute, unpublished data). Affected shelterbelts were characterised by soil compaction associated with the camping of farm animals under the trees. As a consequence the roots had poor mycorrhizal development. It has been suggested that under these conditions heavy rainfall and soil saturation provided ideal conditions for rootlet infection by P. cinnamomi while reducing rootlet regeneration capacity. The imbalance between rootlet death and rootlet regeneration led to mortality (Newhook & Podger 1972). The specific combination of conditions is not likely to occur in extensive exotic plantations or indigenous forests where P. cinnamomi, although present, causes no observable damage.; Host(s): Abelia schumannii, Abies sp., Acacia baileyana, A. verticillata, Acmena smithii, Actinidia deliciosa, Actinostrobus sp., Agathis australis, Astelia trinervia, Banksia sp., Bauera sessiliflora, Betula pendula, Boronia megastigma, Brachyglottis kirkii, Calluna vulgaris, Camellia japonica, Carpodetus serratus, Carya illinoinensis, Castanea sativa, Casuarina cunninghamiana, C. glauca, Chamaecyparis lawsoniana, Coprosma robusta, Coriaria sarmentosa, Corokia buddleioides, Cupressus macrocarpa, Cyathodes juniperina, Daphne odora, Dryandra sp., Elaeocarpus hookerianus, Erica bowieana, E. canaliculata, E. lusitanica, Eucalyptus ficifolia, Fatsia japonica, Forsythia sp., Fuchsia excorticata, Gaultheria antipoda, Geniostoma rupestre var. ligustrifolium, Gevuina avellana, Griselinia lucida, Hakea sericea, Hebe topiaria, Juglans regia, Juniperus communis, J. squamata, Knightia excelsa, Larix decidua, L. kaempferi, Leptospermum scoparium, Leucadendron adscendens, L. argenteum, L. decorum, Leucopogon fasciculatus, Leucospermum sp., Lhotskya alpestris, Lophomyrtus obcordata, Lupinus angustifolius, Lycopodium deuterodensum, Macadamia integrifolia, M. tetraphylla, Melicytus macrophyllus, Meryta sinclairii, Metrosideros excelsa, Myrsine australis, Nestegis lanceolata, Nothofagus fusca, N. menziesii, N. solandri var. cliffortioides, Olearia rani, Passiflora edulis, Persea americana, Phormium tenax, Phyllocladus alpinus, P. trichomanoides, Pieris japonica, Pinus echinata, P. palustris, P. radiata, P. taeda, Platanus sp., Protea sp., Prumnopitys ferruginea, Prunus persica, Pseudopanax arboreus, P. crassifolius, Pseudotsuga menziesii, Rhododendron indicum, Rosmarinus officinalis, Rubus idaeus, Sciadopitys verticillata, Serruria sp., Taxus baccata, Telopea speciosissima, Thryptomene calycina, Vaccinium corymbosum, Vitis rupestris, V. vinifera.

Notes: Recent work (Moyersoen et al. 2003) has shown that P. tinctorius may not be present in New Zealand. These authors showed that on the basis of rDNA internal transcribed spacer (ITS) sequence analysis and spore morphology, the New Zealand collections fell into three phylogenetic groups that have been previously proposed as putative species associated with Eucalyptus spp. in Australia.
Significance: Pisolithus tinctorius sensu lato has a worldwide distribution. It has been shown to be a successful mycorrhizal partner of many plants, including species of Pinus and Eucalyptus (Cairney & Chambers 1997). Marx (1977) showed that it was an early coloniser of eroded soils and mine spoil heaps. It is a very variable species in terms of basidioma and basidiospore morphology (Burgess et al. 1994) and ability to form mycorrhizae (Tonkin et al. 1989). This suggests that several distinct biological species may be involved. Martin et al. (1998) showed that different morphological types associated with specific hosts also differed genetically and that little genetic exchange occurred between morphological types in the field. Moyersoen et al. (2003) have shown that the New Zealand form of the fungus first described by Cunningham (1931c) is in fact a mixture of three species, none of which is P. tinctorius sensu stricto. Each of the three species matched an Australian species associated with eucalypts and acacias. All three species co-occurred locally in the same areas. In New Zealand, these species are associated only with Kunzea and Leptospermum growing in sites affected by geothermal activity (e.g., Whakarewarewa, Waimangu, Wairakei). This species complex has not been found in Pinus or Eucalyptus plantations (Chu-Chou & Grace 1983b).; Host(s): Kunzea ericoides var. microflora, Leptospermum scoparium.

Significance: Found to be closely associated with resinosis of roots and lower stems of Larix decidua and L. kaempferi in Golden Downs Forest (Nelson region). This condition was first discovered in 1935, when many 3-year-old trees that had wilted and died were found to be exuding resin from the roots and butts. Between 1935 and 1937 over 4000 diseased trees were pulled up and burnt. In 1950, planting of larch was resumed and the disease again became apparent (see Bassett 1960). The connection between larch resinosis and P. undulatum was established later by Bassett (Rawlings 1962).; Host(s): Larix decidua, L. kaempferi.

Distribution: Bay of Plenty, Taupo, Hawke’s Bay, Taranaki, Wanganui.; 1st Record: Birch (1937).
Notes: The fungus causing rosellinia root disease of Pinus radiata in localised areas of the North Island has traditionally been known as Rosellinia radiciperda. The name originated with Massee (1896). He had obtained cultures of a fungus causing a root disease of fruit trees planted on cleared indigenous forest sites in New Zealand and identified them as those of an anamorphic fungus, Dematophora necatrix R.Hartig. Later, he received a collection of stromatic ascomata from the base of a dead Malus ×domestica tree, which he named Rosellinia radiciperda. From hyphal characteristics, Massee (1896) maintained that R. radiciperda was the teleomorph of D. necatrix. According to Cunningham (1925a) there is no valid evidence to support this association. Zondag & Gilmour (1963) reported that C.Bassett (unpublished data) had compared cultures of the pathogen obtained from roots of diseased Pinus spp. with ascospore cultures of authenticated Rosellinia radiciperda from Beilschmiedia tawa and found that they were “in no way similar”. Petrini (2003) recorded that, apart from the type collection, all seven hosts of authenticated R. radiciperda in New Zealand were exclusively native to New Zealand. Rosellinia necatrix is not included by Petrini in her list of New Zealand species of Rosellinia although she reported that many of the anamorphic collections on exotic New Zealand hosts in the PDD herbarium “may be, indeed, R. necatrix”. Pennycook (1989) included all records of R. radiciperda, except those from B. tawa, under Rosellinia necatrix Berlese ex Prillieux. The pine pathogen is certainly not Rosellinia radiciperda. It may be R. necatrix, but in the absence of any fruiting structures, this cannot be determined. Despite numerous attempts at inducing fruiting, cultures of the fungus obtained at various times over the past 40 years in the New Zealand Forest Research Institute laboratory have obstinately remained sterile, with one exception of an unverified record of the production of Dematophora fructifications. ‘Rosellinia radiciperda’ has been recorded as a cause of root disease in fruit trees and many indigenous plants (Cunningham 1925a). It may or may not be the fungus recorded on exotic forest plantation trees. The account below describes the fungus known to forest pathologists as ‘Rosellinia radiciperda’; a name that has been maintained purely for convenience.
Significance: Recorded in Pinus radiata forests in the central North Island as the cause of mortality in young stands (areas of up to 0.5 ha) and in single trees. Symptoms are similar to those of magnesium deficiency (needles with bright yellow tips covering the entire crown). Infected trees decline in vigour and eventually die. It occurs in only a few forests, and is of minor economic importance. Laboratory experiments using artificially infected soil have shown that the fungus is a virulent pathogen of P. radiata (C.Bassett, unpublished results; M.A.Dick, unpublished results). Reasons for low virulence in the field are unknown.; Host(s): Chamaecyparis lawsoniana, Eucalyptus obliqua, E. regnans, Larix decidua, L. kaempferi, Pinus patula, P. radiata, P. strobus, Thuja plicata.

Distribution: Northland, Auckland, Coromandel, Bay of Plenty, Rangitikei, Taupo, Wanganui, Wellington, Gisborne, Hawkes Bay, Wairarapa, Nelson, Westland, Marlborough, North Canterbury, Mid Canterbury, South Canterbury, Mackenzie, Central Otago, Dunedin, Southland.; 1st Record: Gadgil (1971).
Significance: Although it is not a primary pathogen, this fungus colonises tissues killed by frost and then invades healthy tissues, causing dieback, cankers, and needle blight (Gadgil 1971). It can be a problem after unseasonable frosts.; Host(s): Pinus contorta, P. radiata.
Type: Caulicolous Fungi; Caulicolous Fungi; Description: Conidiomata stromatic, pycnidial to acervular, scattered to gregarious, occasionally confluent, partly erumpent, roughly circular to oval, black, 0.2–0.4 mm in diameter, opening by an irregular split; on cankers on stems and branches.

Distribution: Auckland, Bay of Plenty, Taranaki, Taupo, Rangitikei, Wanganui, Wellington, Gisborne, Wairarapa, Nelson, Buller, Westland, Marlborough, North Canterbury, Mid Canterbury, South Canterbury, Dunedin, Southland.; 1st Record: Birch (1933: as Coryneum cardinale).
Notes: Swart (1973) considered that differences in the characteristics of conidial appendages used to distinguish S. cardinale (appendages <2 μm long or absent) from S. unicorne (appendages up to 10 μm long) represented extreme variations of a single species. This view is not generally accepted. See also NOTE under Seiridium unicorne (p. 135).
Significance: One of the fungi causing cypress canker. Cypress canker is common throughout New Zealand (van der Werff 1988, Hood et al. 2001). The fungi cause cankering on branches and stems, resulting in crown dieback which leads to malformation, reduced wood quality and, occasionally stem breakage. Some mortality has been recorded, particularly in young stands (Hood et al. 2001). No economic evaluation of the losses is available. Conidia are dispersed by water splash. New cankers are initiated if conidia land on wounds or cracks in otherwise healthy tissue. Pruning increased spread of the disease (Self & Chou 1994, Hood et al. 2001). Van der Werff (1988) reported that incidence of cypress canker in Cupressus macrocarpa decreased as tree age increased and increased with a rise in average mean temperature. No correlation with rainfall was found. Hood et al. (2001) observed a gradual increase in severity of the disease from south to north of the country. A farm forester of much experience with cypresses has noted that C. macrocarpa seems to be much healthier on southern slopes and sheltered sites, indicating that site temperature and exposure are important factors influencing disease severity. He also noted that the disease also seemed to be worse on the windward site of a shelterbelt (D.Hocking, pers. comm.). There is considerable difference in susceptibility between the host species (Gilmour 1966a; Hood et al. (2001): highly susceptible—Chamaecyparis lawsoniana, Cupressus macrocarpa; susceptible—×Cupressocyparis leylandii, Cupressus lusitanica; resistant —Cryptomeria japonica, Cupressus arizonica, C. torulosa, Thuja plicata. Records of Seiridium spp. in the Forest Health database maintained by New Zealand Forest Research Institute show that Seiridium unicorne is more common (77%) than S. cardinale (23%). An exception occurs in the Canterbury region (North, Mid and South Canterbury), where records of S. cardinale were as frequent as those of S. unicorne. Most records of S. unicorne are from C. macrocarpa, C. lawsoniana, and ×Cupressocyparis leylandii. Nearly all records of S. cardinale came from C. macrocarpa. Only S. unicorne was recorded on C. lusitanica. Chemical control of cypress canker is not considered to be necessary. Resistance to this disease is one of the criteria used in the selection of superior individuals of C. macrocarpa for tree improvement field trials (Gea & Low 1997).; Host(s): Chamaecyparis lawsoniana, ×Cupressocyparis leylandii, Cupressus arizonica, C. macrocarpa, C. sempervirens, Thuja plicata.

Conidiomata stromatic, pycnidial, scattered to gregarious, immersed, elongate to oval, dark brown to black, 0.2–0.6 mm long, opening by an irregular split; on cankers on stems and branches. Conidia fusiform, straight or slightly curved, 5-septate, 24–30 × 8–10 μm, smooth, apical and basal cells hyaline, intermediate cells pale brown to brown; apical cell with a single, tubular appendage, 5–8 μm long; basal cell appendage single, tubular, centric, 3–6 μm long.
Distribution: Northland, Auckland, Coromandel, Waikato, Bay of Plenty, Taranaki, Taupo, Rangitikei, Wanganui, Wellington, Gisborne, Hawkes Bay, Wairarapa, Nelson, Buller, Westland, Fiordland, Marlborough Sounds, Marlborough, North Canterbury, Mid Canterbury, South Canterbury, Mackenzie, Otago Lakes, Central Otago, Dunedin, Southland.; 1st Record: Fuller & Newhook (1954: as Monochaetia unicornis).
Notes: The teleomorph is present but uncommon in New Zealand, and isolations from cypress cankers almost invariably yield the anamorph. Boesewinkel (1983) considered that many of the collections identified as Seiridium unicorne in New Zealand could be distinguished as a separate species, S. cupressi, but Chou (1989) found that S. cupressi and S. unicorne were morphologically indistinguishable. Barnes et al. (2001) reported that while S. unicorne and S. cupressi could not be distinguished on morphological grounds, they could be separated using sequence data from either the β-tubulin or histone H3 gene. The two clades defined by Barnes et al. (2001) did not coincide exactly with Boesewinkel’s two morphological groupings, but they concluded that the two New Zealand isolates of ‘S. unicorne’ included in their study should be referred to S. cupressi. Recent reports from Europe, based on molecular characteristics (Graniti 1998; Moricca et al. 2000) support the existence of three species there, and indicate that a fourth species may be present in Australia (Graniti 1998). Until the New Zealand situation is clarified, I have included records of S. cupressi under S. unicorne.

Significance: This ubiquitous fungus, generally considered to be a wound pathogen, is also capable of infecting undamaged young tissue. It attacks tissues weakened or damaged by frost, drought, hail, or mechanical injury, and causes two main types of damage: Leader dieback: Infection of tissue produced in the current season results in dieback of terminal and lateral shoots. The first sign is a small, dark brown spot on the non-suberised young shoot; this develops into a purple to dark brown lesion which does not extend to the suberised part of the stem. The shoot wilts at the point of infection and the part above the lesion dies. Warm temperatures (20–25pC) and humid conditions favour infection (Chou 1982). Leader dieback is a problem in a few localised areas, principally closed valley systems. Malformation associated with leader dieback can cause significant downgrading of sawlog quality. It was responsible for an estimated loss of $5.4 million (1988 dollars) over one rotation in a 6000 ha plantation (New 1989). Crown wilt and whorl canker: Infection of the woody stem can lead to death of a considerable portion of the crown, the extent depending on position of the point of entry. The fungus invades through wounds and pruning stubs are common entry sites. Depressions form above and below infected stubs because the cambium is killed, causing a type of injury known as whorl canker. If all pruning stubs in a branch whorl are affected, the whole portion of the crown above the whorl often dies. Infection of woody tissues is first indicated by discoloration and death of the inner bark, which becomes brown and eventually black. The fungus reaches the pith through the ray cells and invades further ray cells as it moves up the stem. Infected wood ranges in colour from light grey to dark blue grey. This ‘blue stain’ is usually seen in cross section as wedge-shaped sectors. Wilting of shoots or the whole crown follows invasion of the wood. Chou & MacKenzie (1988) showed that the extent of pruning affected susceptibility of Pinus radiata trees to S. sapinea. Where 40–50% of the green crown was removed in a single lift, 65% of the trees became infected; only 8% were infected where pruning involved 25% crown removal. Chou & MacKenzie (1988) also showed that infection was restricted to a short period during summer months. Chou (1987) found that water stress caused by drought was a predisposing factor. Damage from whorl canker and crown wilt can therefore be minimised if 25% or less of the green crown is removed in one pruning lift timed to avoid hot and dry periods in summer. Sphaeropsis sapinea is also important as a cause of sap-stain in logs and sawn timber.; Host(s): Chamaecyparis lawsoniana, Pinus canariensis, P. contorta, P. elliottii, P. muricata, P. nigra subsp. laricio, P. palustris, P. ponderosa, P. radiata, P. taeda, Pseudotsuga menziesii.
Type: Powdery Mildews; Description: Mycelium superficial, evanescent, occasionally dense, white, hyphae 3–5 μm wide; on leaves. Appressoria not lobed. Ascomata not known in New Zealand. Conidiophores 250–350 × 7–13 μm, foot cell straight or tapering towards the base. Conidia produced in moderately long or long chains, oval, 0-septate, 26–33 × 16–22 μm, smooth, hyaline.
Distribution: Northland, Auckland, Coromandel, Bay of Plenty, Taupo, Wellington, Nelson, Mid Canterbury, Otago Lakes, Southland.; 1st Record: Cunningham (1922: as Sphaerotheca humuli).
Significance: This fungus has been recorded under a number of different names. Dingley (1969) reported it under the name Sphaerotheca macularis (Fries) Jaczewski as the cause of a troublesome powdery mildew on strawberry. Boesewinkel (1980, 1981a) recorded it on a number of Eucalyptus species as S. alchemillae (Greville) Junell. It is the most common of three powdery mildew fungi found on Eucalyptus spp. (The other two are Erysiphe orontii and S. pannosa.) As it is not possible to differentiate these fungi in the field, records generally refer to ‘powdery mildew’ rather than to individual species. Powdery mildew can be a serious problem in glasshouse-grown Eucalyptus seedlings, severe infection causing necrosis of young leaves and shoots. Sphaerotheca aphanis observed in nursery seedlings has been found to persist under field conditions (I.A.Hood, New Zealand Forest Research Institute, pers. comm.).; Host(s): Eucalyptus albens, E. cinerea, E. crebra, E. diversicolor, E. diversifolia, E. grossa, E. megacarpa, E. nitens, E. nutans, E. paniculata, E. tereticornis, E. torquata, Rubus australis, R. cissoides.

Conidia produced in chains, oval, 0-septate, 27–31 × 15–18 μm, smooth, hyaline.
Distribution: Auckland, Wellington, Gisborne, Hawkes Bay, North Canterbury, Mid Canterbury, Chatham Islands.; 1st Record: Brien & Dingley (1951: as Oidium sp.).
Significance: Infection occurs in late spring and early cucurbit crops can be seriously damaged.; Host(s): Carica ×heilbornii nm. pentagona, C. microcarpa, C. papaya, C. pubescens, *Coriaria angustissima, C. arborea, C. lurida, Hibiscus syriacus, Hoheria lyallii, H. populnea, Olearia furfuracea, Thunbergia gregorii.
Type: Powdery Mildews; Description: Mycelium superficial, moderately dense to dense; on leaves, shoots, and inflorescences. Primary mycelium white, composed of flexuous hyphae; secondary mycelium brown, composed of straight hyphae; hyphae of both types 5–6 μm wide. Appressoria not lobed.

Significance: The cause of ‘rose mildew’, a damaging disease of cultivated roses. When infection is severe, entire leaves, long stretches of stem, buds, and flowers become covered with white, powdery mycelium; leaves wither and growth is checked. Leaf infection in peach and apricot is uncommon but russeting of fruit is troublesome in susceptible varieties (Atkinson 1971). Boesewinkel (1981a) has shown that this species occurs on species of Eucalyptus. Because it is difficult to distinguish from other powdery mildews in the field, its significance as a pathogen of eucalypts is discussed under Sphaerotheca aphanis.; Host(s): ): Eucalyptus albens, E. deglupta, E. eremophila, E. moluccana, E. tereticornis, Malus × domestica, Prunus armeniaca, P. persica, Rosa chinensis × multiflora, *R. multiflora, *R. rubiginosa, * Rosa sp.

Distribution: Waikato.; 1st Record: Johnston & McKenzie (1982: as Seimatosporium vaccinii).
Significance: Reported as the cause of a leaf spot of minor importance on blueberry (Johnston & McKenzie 1982).; Host(s): Vaccinium ashei, V. corymbosum.
Type: Xylophilous Fungi; Description: Isolated from stained sapwood associated with tunnels of pinhole borers (Platypus spp.) and not seen fruiting in nature. The following description is from cultures on 2% malt extract agar. Colonies slow-growing (40 mm in 14 days, 20 degrees), dark olive green to almost black with a pale grey margin, flat, with some shiny patches in older cultures due to production of conidia, aerial mycelium greyish white, sparse; reverse dark olive green; submerged hyphae brown, smooth, septate, 2–3 μm wide, sometimes fasciculate; aerial hyphae pale brown, septate. Conidiogenous cells arising from undifferentiated hyphae, sometimes in a terminal position but more commonly integrated in small side branches, straight or flexuous, septate, acicular, widest at the base and tapering towards the apex, 20–80 × 1.5– 2.5 μm, the apical part forming conidia by sympodial growth giving rise to a short denticulate conidiiferous rachis, hyaline; sometimes proliferating at, or a little below the apex, giving rise to other short, denticulate rachides. Conidia fusiform to narrowly clavate, 0-septate, 5–7.5 × 2–3.5 μm, smooth, hyaline; also formed laterally on un-differentiated hyphae.
Distribution: Auckland, Bay of Plenty, Taupo, Hawkes Bay, Westland, North Canterbury, Mid Canterbury.; 1st Record: Faulds (1977).
Significance: Sporothrix nothofagi is found in stained sapwood associated with tunnels of three species of native pinhole borers (Platypus apicalis White, P. gracilis Broun, and Treptoplatypus caviceps (Broun)). These three borers attack living trees of all Nothofagus spp., and P. apicalis and P. gracilis also attack living Weinmannia racemosa. Tunnels bored by Platypus adults normally extend radially in the sapwood to a zone near the heartwood boundary where they branch tangentially (Milligan 1979). A bluish-black stain, about 120 mm long, tapering gradually from 5 mm wide towards both ends, is always associated with the tunnels. Sporothrix nothofagi can be isolated from hyphae present in the stained area (Faulds 1973). Severe pinhole borer attacks (10 or more holes per 100 cm2) on healthy Nothofagus or W. racemosa, or light to moderate attacks followed by an abnormally dry season can kill trees of merchantable size when S. nothofagi spreads from the tunnels into sapwood. Conclusive evidence of pathogenicity of S. nothofagi to N. fusca has been demonstrated by Faulds (1977) and to W. racemosa by Payton (1989).; Host(s): Nothofagus fusca, N. solandri var. cliffortioides, N. truncata, Weinmannia racemosa.

Hyphal system dimitic. Cystidia none. Basidiospores elliptic-cylindrical, 6–8 × 2–3 μm, amyloid.
Distribution: Auckland, Coromandel, Waikato, Bay of Plenty, Taupo, Wellington, Nelson.; 1st Record: Birch (1937).
Significance: Although usually a saprobe on dead wood, this fungus has been occasionally recorded as a parasite infecting pruning wounds and causing a sap rot in Pinus spp., including P. radiata (Gilmour 1966a).; Host(s): Agathis australis, Dacrydium cupressinum, Dracophyllum sp., Larix decidua, Nothofagus menziesii, Pinus nigra subsp. laricio, P. radiata, P. taeda, Pseudotsuga menziesii.
Type: Caulicolous Fungi; Description: Ascomata apothecial, aggregated in groups, disc pale yellow, surrounded by a broad, white-lobed sterile margin which protrudes from the surface, 0.2–0.4 mm in diameter; deeply immersed in wood.

Distribution: Auckland, Bay of Plenty, Taupo, Waikato, Wanganui, Wellington, Hawkes Bay, Nelson, Buller, Westland, Marlborough, Mid Canterbury.; 1st Record: Gadgil & Dick (2000a).
Significance: Associated with death and casting of foliage of Chamaecyparis lawsoniana on the west coast of the South Island. Older foliage in the lower and middle crown is affected first and as this is cast, trees develop a hollow crown with an outer fringe of green leaves. Continued defoliation over several years has led to the death of some trees. The disease has not proved to be serious elsewhere in New Zealand.; Host(s): Chamaecyparis lawsoniana, Thuja plicata.
Type: Corticolous Fungi; Description: Ascomata stromatic, perithecial, aggregated in groups of several hundred, visible as papillae protruding through the surface of the stroma, globose to subglobose, orange becoming dark olive green, 0.2–0.3 mm in diameter, ostiole distinctly papillate, immersed in a single layer in a convex, orange-pink to grey pulvinate stroma up to 10 mm in diameter; on bark on stems. Asci cylindrical, 70–110 × 5–11 cm. Ascospores elliptical, 1-septate, 9–14 × 4–6 m, verrucose, hyaline.

Significance: Nag Raj (1993) recorded the association of this fungus with branch and twig cankers and necrotic needles of Abies, Picea, and Pinus species in Canada. It does not appear to act as a pathogen in New Zealand although it is very common as an endophyte in P. radiata needles. In Tasmania it has been recorded as a secondary invader of needles of P. radiata trees suffering from spring needle-cast (Podger & Wardlaw 1990).; Host(s): Pinus radiata.

Distribution: Auckland, Coromandel, Waikato, Bay of Plenty, Rangitikei, Wanganui, Wellington, Hawkes Bay, Nelson, Marlborough, Mid Canterbury, Central Otago.; 1st Record: Kirk (1897: uredinia and telia on Prunus, as Puccinia pruni-spinosae); Cunningham (1923a: spermagonia and aecia on Anemone, as Puccinia pruni-spinosae).
Significance: Attacks leaves, fruits, and shoots of peach and nectarine, fruits and leaves of almond and apricot, and leaves of cherry and plum. The rust is more common in warmer northern areas. It is seldom a problem in commercial orchards, which are regularly sprayed to control brown rot. Unsprayed trees may be severely damaged. Infection leads to premature defoliation, with consequent stunting; small trees may be killed. The fungus overwinters in twigs as uredinia, which produce a new crop of urediniospores in the spring. Presence of the aecial host is therefore not necessary for the continued spread of the rust.; Host(s): Spermagonia and aecia on Anemone coronaria. Uredinia and telia on Prunus armeniaca, P. avium, P. cerasifera, P. ×domestica, P. dulcis, P. persica, P. persica var. nucipersica, P. salicina.

Galls are perennial, usually 2–8 cm in diameter but up to 35 cm; on petioles and seed pods they are smaller, with a blister-like, green to purplish appearance; stem and branch galls are usually larger and olive brown. Uredinia cinnamon brown, mixed with chocolate brown telia. Urediniospores ellipsoid to oblong, 30–45 × 16–26 μm, bright yellow becoming yellowish brown, reticulate; pedicel elongated, hyaline. Teliospores three in a head on one sporophore, which does not have a lateral vesicle; teliospores depressed globose to subglobose, 16–23 × 21–26 μm, pallid chestnut brown, densely covered with warty spines arranged in lines.
Distribution: Northland, Auckland, Coromandel, Waikato, Bay of Plenty, Taranaki, Taupo, Rangitikei, Wanganui, Gisborne, Hawkes Bay, Nelson, Marlborough Sounds, Marlborough, Mid Canterbury, Dunedin.; 1st Record: Cunningham (1923a).
Significance: Because galls impede the transpiration flow, branches beyond the gall make little growth, produce only a few leaves and begin to die back. When infection is severe, whole trees may be killed within a few seasons. In the 1920s, this rust was responsible for the failure of 1800 ha of Acacia decurrens planted to start a tannin industry. Until recently, susceptible host species were not grown commercially but there are plans for planting substantial areas of A. mearnsii and A. dealbata in Northland. At present, the effect U. notabile on these plantations cannot be predicted.; Host(s): Acacia baileyana, A. dealbata, A. decurrens, A. mearnsii.
Type: Rust and Smut Fungi; Description: Spermagonia numerous, aggregated, erumpent, light rust-coloured, powdery, minute, up to 0.8 mm in diameter, on small galls; on both sides of juvenile leaves, phyllodes, and petioles, and on depressed cankers up to 4 mm long on twigs and small branches. Uredinia pustular, together with the telia partially surrounding the spermagonia in circular or elliptical groups up to 4 mm in diameter. Urediniospores intermixed with the teliospores, elliptical, 34–48 × 16–22 μm, pallid yellow chestnut brown, densely verrucose. Telia pustular, together with the uredinia partially surrounding the spermagonia in circular or elliptical groups up to 4 mm in diameter. Teliospores intermixed with the urediniospores, solitary on sporophores, which have a lateral vesicle; teliospores depressed globose to globose, 19–26 × 25–34 μm, dark chestnut brown, smooth; vesicle globose or obovate, 25 × 20 μm, hyaline.
Distribution: Auckland, Coromandel, Waikato, Bay of Plenty, Taranaki, Taupo, Rangitikei, Wanganui, Wellington, Gisborne, Hawkes Bay, Wairarapa, Nelson, Buller, Westland, Mid Canterbury.; 1st Record: Cunningham (1923a).
Significance: Generally of minor importance. When infection is severe, cankers may girdle twigs and branches, causing dieback of parts of the crown.; Host(s): Acacia melanoxylon.
Type: Rust and Smut Fungi; Description: Spermagonia crowded, rusty brown, minute; on both sides of phyllodes. Uredinia brown, pustulate, erumpent, up to 1 mm in diameter, often confluent. Urediniospores rusty brown in mass, fusiform to oval, 40–55 × 21–23 μm, finely verruculose, yellowish brown to golden brown, with a hyaline apiculus. Teliospores solitary at the end of a sporophore, which has a lateral vesicle, produced in large numbers later in the season, often intermingled with the urediniospores at first, rusty brown, depressed globose to subglobose, 16–22 × 22–28 μm, smooth, yellowish brown, forming a brown crust; sporophore hyaline, 80 sm or longer, lateral vesicle globose, 20 μm in diameter, hyaline.
Distribution: Mid Canterbury.; 1st Record: Laundon & McCully (1978).
Significance: Very limited local distribution; of no importance.; Host(s): Acacia pycnantha.
Type: Rust and Smut Fungi; Description: Spermagonia dark brown, pustulate, minute, associated with telia on the surface of distorted, inflated, brown galls; on phyllodes, branches, stems, and seed pods. Galls are perennial, up to 5 cm in diameter on branches, smaller on phyllodes and seed pods. Uredinia not known. Teliospores cinnamon brown, powdering the surface of the galls, three in a head on one sporophore; teliospores depressed globose to subglobose, 14–20 × 18–25 μm, cinnamon brown, strongly striate, the striations continuous and converging at the poles; sporophore hyaline, with no lateral vesicle, soon deciduous.
Distribution: Northland, Auckland, Coromandel, Waikato, Bay of Plenty, Taranaki, Taupo, Wanganui, Wellington, Gisborne, Nelson, Mid Canterbury, South Canterbury, Dunedin.; 1st Record: Cunningham (1923a).
Significance: Galls cause dieback of branches and stems. Small trees die if galls form on the main stem. The host species are not grown commercially and the rust has no economic significance.; Host(s): Acacia paradoxa, A. ulicifolia, A. verticillata.
Type: Foliicolous Fungi; Description: Ascomata stromatic, perithecial, scattered, subcuticular, immersed, globose, black, 0.12–0.16 mm in diameter, ostiole papillate, protruding, surrounded by brown setae up to 60 μm long; on both sides of fallen leaves. Asci obclavate, 45–55 × 9–10 μm. Ascospores elliptical to obovoid, 1-septate, 10–14 × 4–5 μm, smooth, yellowish. Conidia solitary or in short branched chains, fusiform to cylindrical, 0–1-septate, 10–12 × 3–5 μm, smooth or finely verruculose, yellowish.
Distribution: Auckland.; 1st Record: Samuels & Sivanesan (1975).
Significance: None. Found in mixture with Venturia inaequalis on fallen apple leaves.; Host(s): Malus ×domestica.
Type: Foliicolous Fungi; Description: Ascomata stromatic, perithecial, scattered, immersed at first but erumpent later, globose to subglobose, olive brown, 0.1–0.2 mm in diameter, ostiolate; on both sides of fallen leaves. Asci saccate-cylindrical, 48–56 × 5–6 μm. Ascospores somewhat clavate, 1-septate, 12–16 × 3–5 μm, smooth, yellowish green. Conidia bluntly fusiform, 0-septate, 12–18 × 4–5 μm, smooth, yellowish brown.
Distribution: Auckland, Waikato, Bay of Plenty, Wellington, Gisborne, Nelson, Central Otago.; 1st Record: Kirk (1904: as Cladosporium carpophilum).
Significance: On living leaves, shoots, and fruit, only the Fusicladium state is found. Only fruit infection (causing the disease known as ‘scab’) is of economic significance. Infected fruit has sharply defined, dark green to black spots, 2–3 mm in diameter, often with distortion and cracking. When no control measures are taken, scab may cause serious loss (Atkinson 1971). The teleomorph is produced on fallen leaves during the winter.; Host(s): Prunus armeniaca, P. cerasifera, P. ×domestica, P. dulcis, P. mume, P. persica, P. persica var. nucipersica, P. salicina.
Type: Foliicolous Fungi; Description: Ascomata stromatic, perithecial, aggregated in groups, immersed at first, erumpent later, globose, black, 0.1–0.2 mm in diameter, ostiole prominent, often surrounded by a few brown setae; on the lower surfaces of fallen leaves. Asci cylindrical, 60–70 × 10–12 μm. Ascospores elliptical, 1-septate, 12–15 × 6 μm, smooth, olivaceous green. Conidia oblong fusiform, 0-septate, 20–25 × 4–5 μm, smooth, pale green.
Distribution: Mid Canterbury, Central Otago.; 1st Record: Brien and Dingley (1955: as Fusicladium (Cladosporium) carpophilum).
Significance: On living leaves and fruit, only the Fusicladium state is found. Infection of fruit causes spotting and makes the fruit unsaleable. The disease is un-common and of little significance (Atkinson 1971).; Host(s): Prunus avium.
Type: Foliicolous Fungi; Description: Ascomata stromatic, perithecial, aggregated in groups, immersed, globose, brown, 0.1–0.2 mm in diameter, ostiole prominent, with or without blackish brown setae; on both sides of fallen leaves. Asci saccate, 40–70 μm long. Ascospores elliptical, 1-septate, 12–16 × 5–7 μm, smooth, olivaceous brown. Conidia napiform, 1-septate, 16–24 × 7–10 μm, smooth, yellowish brown.
Distribution: Auckland, Waikato, Wanganui, Hawkes Bay, Nelson, Fiordland, Mid Canterbury, South Canterbury, Dunedin, Chatham Islands.; 1st Record: Kirk (1894: as Fusicladium dendriticum).
Significance: ‘Black spot’, caused by V. inaequalis, is the most serious disease of apples in New Zealand. On living leaves, shoots, and fruit, only the Fusicladium state is found, forming olivaceous brown, velvety, often coalescing colonies. Infected leaves are often distorted and fall prematurely. On fruit, lesions appear as rough corky sunken areas with greyish edges. If not controlled by fungicides, black spot may cause a total crop loss (Atkinson 1971). The fungus lives as a saprobe on fallen leaves through the winter, producing ascomata in the spring.; Host(s): Malus ×domestica.
Type: Foliicolous Fungi; Description: Ascomata stromatic, perithecial, aggregated in groups, immersed, globose, brown, 0.1–0.25 mm in diameter, ostiole papillate, occasionally surrounded by up to 50 brown setae; on the lower surfaces of fallen leaves. Asci saccate, 40–70 μm long. Ascospores elliptical, 1-septate, 14–20 × 4–8 μm, smooth, olivaceous. Conidia broadly fusiform, 0–1-septate, 17–28 × 8–10 μm, smooth, olivaceous brown.
Distribution: Auckland, Waikato, Wellington, Hawkes Bay, Nelson, Dunedin.; 1st Record: Curtis (1921).
Significance: The symptoms of ‘black spot’ of pears and apples are very similar. On living leaves, shoots, and fruit, only the Fusicladium state is found, forming dark olivaceous brown, velvety colonies. The fungus lives as a saprobe on fallen leaves during the winter, producing ascomata in the spring.; Host(s): Pyrus communis.
Type: Foliicolous Fungi; Description: Conidiomata stromatic, acervular, scattered to gregarious, subepidermal, brown, up to 0.3 mm in diameter; on large, confluent, necrotic leaf spots on both sides of leaves.
