Mycosphaerella cryptica (Cooke) Hansf. 1956

Type: Foliicolous Fungi; Description: Ascomata perithecial, closely aggregated, subepidermal, later partly erumpent, globose, black, up to 0.15 mm in diameter; on circular to irregular, discrete or confluent leaf spots which are variable in size. Asci obclavate to subsaccate, 32–45 × 10–15 μm. Ascospores ellipsoidal, 1-septate, 12–16 × 2.5–5 μm, rounded at both ends. Conidiomata acervular, subcuticular becoming erumpent, dark brown to black, up to 0.15 mm wide. Conidia cylindrical, straight or slightly curved, 0-septate, 9–18 × 4–6 μm, truncate at base with a small frill. Leaf spots occur on both sides of the leaves, are red brown in colour at first, frequently with a prominent purple margin, becoming dark grey with age; infected leaves are often distorted. The fungus also infects petioles and twigs, causing the formation of cankers up to 25 mm long, which often exude gum.
Distribution: Northland, Auckland, Coromandel, Waikato, Bay of Plenty, Taranaki, Taupo, Rangitikei, Wanganui, Wellington, Gisborne, Hawkes Bay, Wairarapa, Nelson, Buller, Westland, Marlborough Sounds, Marlborough, North Canterbury, Mid Canterbury, Dunedin.; 1st Record: Weston (1957: as Mycosphaerella nubilosa).
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.
