Venturia pyrina Aderh. 1896

Description

Type: Foliicolous Fungi; Description: Ascomata stromatic, perithecial, aggregated in groups, immersed, globose, brown, 0.1–0.25 mm in diameter, ostiole papillate, occasionally surrounded by up to 50 brown setae; on the lower surfaces of fallen leaves. Asci saccate, 40–70 μm long. Ascospores elliptical, 1-septate, 14–20 × 4–8 μm, smooth, olivaceous. Conidia broadly fusiform, 0–1-septate, 17–28 × 8–10 μm, smooth, olivaceous brown.

Distribution

Distribution: Auckland, Waikato, Wellington, Hawkes Bay, Nelson, Dunedin.; 1st Record: Curtis (1921).

Notes

Pathogenicity

Significance: The symptoms of ‘black spot’ of pears and apples are very similar. On living leaves, shoots, and fruit, only the Fusicladium state is found, forming dark olivaceous brown, velvety colonies. The fungus lives as a saprobe on fallen leaves during the winter, producing ascomata in the spring.; Host(s): Pyrus communis.
