Cryptosporiopsis eucalypti Sankaran & B. Sutton 1995

Description

Type: Foliicolous Fungi; Description: Conidiomata acervular, solitary, globose, subepidermal, pale brown, opening by rupture of overlying host tissue which appears as a flap hinged on one side, 0.15–0.5 mm in diameter; on large (up to 10 mm in diameter), discrete, light brown leaf spots on both sides of leaves. Conidia ellipsoid, 0-septate, 15–17 × 7–8 μm, apex rounded, base abruptly tapering to a truncate scar, hyaline.

Distribution

Distribution: Northland, Auckland, Bay of Plenty, Taranaki, Taupo, Wanganui, Rangitikei, Wellington, Gisborne, Hawkes Bay, Wairarapa, Buller, North Canterbury, Mid Canterbury, Dunedin.; 1st Record: Gadgil & Dick (2000b).

Notes

Pathogenicity

Significance: Pathogenicity of this fungus to Eucalyptus grandis and to E. tereticornis has been established (Sankaran et al. 1995). Although it is widespread in New Zealand and associated with premature leaf cast in many areas, the species of eucalypts affected are not important plantation species.; Host(s): Eucalyptus calophylla, E. ficifolia.
