CULTURES AND ANAMORPH

Colonies on 2% Difco Oatmeal Agar at ca. 20°C and under 12 h fluorescent light reaching the edge of 9 cm Petri dish in 2 wk, whitish, felty, slightly zonate, with diffuse margins, with amber (47) pigments diffused beyond colonies, becoming dull green (70) at center and primrose (66) to honey (64) towards margins; reverse citrine (13).

Sporulating regions at margins of colonies, buff (45).

Conidiogenous structure with Periconiella-like branching pattern as defined in Ju and Rogers (1996).

Conidiophores mononematous, composed of main axis and, infrequently, one major branch, hyaline, smooth to finely roughened, 3-3.5 µm diam, with two to four conidiogenous cells arising in whorls along main axis and major branch.

Conidiogenous cells cylindrical, hyaline, roughened, 8-15 x 2.5-4 m m. Conidia produced holoblastically in sympodial sequence.

Conidia hyaline, smooth, ellipsoid, with flattened base, 4.5-6.5 x 2.5-3.5 µm.
