Carmichaelia sp.

Auckland, Little Barrier Isl., December 1947, J.M.D. type collection.

Perithecia scattered or aggregated into groups of 2-10 seated on a poorly developed erumpent stroma, globose 0-3-0-5mm. coral or salmon pink, collapsing when dry, ostiole umbilicate ; perithecial wall pseudoparenchymatous 120, thick, outer cells 10-20, diameter, walls lightly thickened and pigmented, subhymenial cells 3-4,ri. diameter, walls thickened and pigmented. Asci elavate or cylindrical 50-90 x 8-10A, 4-8 spored, biseriate; pseudoparaphyses filamentous, branched. Spores one-septate, sometimes unequally divided by septa, fusiform, elliptical or oval, occasionally allantoid, rarely spherical, 9-26 x 4-8µm smooth, hyaline.
New Zealand.
Carmichaelia sp.
Perithecia libere sparsa vel gregaria, in stromate parvo et erumpenti, globosa 0 - 3-0 - 5mm. diameter, corallina, corruentia ; ostiolo umbilicato ; pariete perithecii pseudoparenchymato 120, crasso ; cellulis densatis et leviter tinctis. Asci cylindrici vel clavati 50-90 x 8-10,u; 4-8 sporis biseriatis; pseudoparaphysibus. Sporae uniseptatae, fusiformes, ellipticae vel ovatae, 9-26 x 4-8,t, leves, hyalinae.
Similar to N. cinnabarina differing in that Perithecia are lighter coloured and spores irregular in shape and size. Perithecia collapse when dry. They are aggregated into clusters of 3 to 10 on a small erumpent stroma.
LOCALITY: Little Barrier Island, New Zealand.
Type: Corticolous Fungi; Description: Ascomata stromatic, perithecial, scattered or aggregated in groups of 2–10, flattened globose, orange-yellow to salmon pink, finely warted, 0.3–0.5 mm in diameter, ostiole papillate, superficial, on a poorly-developed erumpent stroma; on bark on stems. Asci clavate, 50–95 × 8–15 μm. Ascospores elongate elliptical, 1-septate, 15–25 × 4–8 μm, smooth, hyaline. Conidia lemon-shaped, 0-septate, 10–18 × 7–9 μm, smooth, hyaline at first but becoming thick walled and greenish.
Distribution: Auckland, Northland, Coromandel, Wanganui, Nelson.; 1st Record: Dingley (1951: as Nectria hauturu).
Significance: None.; Host(s): Beilschmiedia tawa, Carmichaelia sp., Citrus limon, Coprosma grandifolia, C. lucida, Lupinus arboreus, Melicytus ramiflorus, Olearia sp., Pittosporum tenuifolium, Rhopalostylis sapida, Ripogonum scandens, Sophora microphylla, S. tetraptera.
On dead branches of Macropiper excelsa Auckland Prov., Whangapoua Saddle, Coromandel Peninsula, 5,1X.1963, J.M.D., DAOM 109379.
Conidia limoniform, 12.5-17(-18.5) X 8-9µm.
Dingley (1956) indicated that her Nectria hauturu described from Little Barrier L, should be regarded as a synonym of N. ralfsii; she remarked that the conidial state is present on the New Zealand collections which she had seen. Ellis (1971) included the conidial state as Myrothecium but Tulloch (1972) excluded it.
