Collections Examined

REPRESENTATIVE CULTURES: PDDCC 6626, 6627.

Description

COLONY MORPHOLOGY OA & ME: Colonies 15-25 mm diam. after 7 days. Mycelium; cottony, fine, medium to dark grey or greenish grey. Reverse; OA grey, occasionally also red; ME dark grey. CHLAMYDOSPORES: None. CONIDIA: Uniform in shape, oblong with rounded ends. (3-)4-6(-7) x 1-2 (-3) µm. PYCNIDIA: Solitary or in groups of 8-10 with confluent walls, with dark setae which vary in number and length.

Habitat

OCCURRENCE: Saprophyte, isolated from soil and dead plant material.

Notes

NOTES: Although the presence of setae on pycnidia has been considered to be a characteristic of Pyrenochaeta, Phoma leveillei has been placed in Phoma because its phialides are typical of Phoma (Boerema & Bollen 1975) and not held in chains as is characteristic of Pyrenochaeta. For a discussion of Pyrenochaeta see Schneider (1979).
