CULTURES AND ANAMORPH

Colonies on SME Agar (see Kenerley and Rogers, 1976) incubated at ca 22C under 10 h per day fluorescent light not covering 9 cm diam. Petri plate in 3 wk, thin, radiating outward in fan-like pattern, greenish black.  Conidia produced in inoculation spots after 18 d.

Conidiophores arising from prostrate hyphae, mostly mononematous, 600 m long or longer x 5-6 m broad, at first hyaline, becoming brown, slightly roughened, bearing branches which in turn bear false verticils of conidiogenous cells.

Conidiogenous cells 15-20 m long x 4-5 m broad, becoming somewhat inflated from conidial production. Conidia produced holoblastically.

Conidia hyaline, more or less rectangular with rounded to acute apices and flattened bases indicating their former attachment to the conidiogenous cell, (6-)10-13 x 2-3 m. Referable to Nodulisporium. Conidiophores Periconiella-like.
