CULTURES AND ANAMORPH
Colonies on Difco Potato Dextrose Agar with 5 g/1 yeast extract added (PDYA), incubated at ca 22ºC under 10 h per day fluorescent light, covering 9 cm diam. Petri plate in 10 d, lanose, at first white, becoming grey at centre and then throughout. Reverse reddish brown.
Anamorph produced in grey areas.
Conidiogenous structure Periconiella-like as defined by Ju and Rogers (1996), at first hyaline becoming brown and minutely roughened to coarsely warted, up to at least 700 µm high and 6 µm broad, branching asymmetrically to verticillately, terminating in conidiogenous cells.
Conidiogenous cells cylindrical to cylindric-clavate, 7-40 x 3-5 µm, producing conidia holoblastically, becoming somewhat distended following abundant conidial production in a limited area.
Conidia hyaline, subglobose to ellipsoidal, smooth, rounded at apices, with flattened bases indicating their former point of attachment to the conidiogenous cell, 6-8 x 2.5-3.5 µm.
