Mycosphaerella nubilosa (Cooke) Hansf. 1956

A leaf blotch [of Eucalyptus gigantea] caused by Mycosphaerella nubilosa has been recorded by Weston (1957) as common on leaves of trees at the sapling stage; he reported that it is common on leaves of plants in seedling beds in nurseries.

Mycosphaerella nubilosa (Cooke) Hansf. 1956

Type: Foliicolous Fungi; Description: Ascomata perithecial, densely scattered, subepidermal, partly erumpent, globose, black, up to 0.15 mm in diameter, ostiolate; on irregular, often confluent spots on the lower surfaces of juvenile leaves, creamy yellow to pale brown areas on both leaf surfaces at first, but becoming grey-black on the lower surface due to the presence of ascomata. Asci ellipsoid to subsaccate, 40–50 × 16–20 μm. Ascospores ellipsoid, 1-septate, 12–17 × 2.5–4.5 μm, ends rounded, hyaline.
Distribution: Northland, Auckland, Coromandel, Waikato, Bay of Plenty, Taupo, Wellington, Gisborne, Hawkes Bay, Wairarapa, Buller, Kaikoura.; 1st Record: Dick (1982).
Significance: Juvenile foliage of E. globulus is particularly susceptible to infection. Although Park & Keane (1982) reported almost complete defoliation of a stand of E. globulus infected by M. nubilosa in Victoria, Australia, the fungus has not caused any significant damage in New Zealand.; Host(s): Eucalyptus cypellocarpa, E. globulus subsp. globulus, E. globulus subsp. bicostata, E. globulus subsp. maidenii, E. gunnii, E. johnstonii, E. nitens, E. viminalis.
