Coniothyrium ovatum H.J. Swart 1986

Description

Type: Foliicolous Fungi; Description: Conidiomata pycnidial, gregarious, subglobose to elliptical, sub-stomatal, dark brown to black, 50 μm in diameter, with a black cirrus of conidia exuding from the mouth of the conidioma; on both sides of leaves, not associated with necrotic spots or discoloration. Conidia ovate, 0-septate, 10–14 × 5–6 μm, with finely roughened walls, apex rounded, base truncate, olivaceous brown.

Distribution

Distribution: Northland, Auckland, Bay of Plenty, Taranaki, Rangitikei, Wanganui, Wellington, Gisborne, Hawkes Bay, Nelson, Mid Canterbury.; 1st Record: Ridley (1995).

Notes

Pathogenicity

Significance: Crous et al. (1989) reported that in South Africa, C. ovatum was associated with necrotic lesions on juvenile leaves. Swart (1986a) noted that the conidiomata were on necrotic leaf spots, 1 mm in diameter. No lesions or spots are associated with C. ovatum in the New Zealand material and the fungus appears to cause no damage here.; Host(s): Eucalyptus leucoxylon.
