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 1.5-2 wk, whitish, felty, azonate, with diffuse margins, becoming honey (64); reverse citrine (13).

Sporulating regions scattered over entire surface of colony, but with more abundant sporulation on tufts of hyphae at edge of colony, pale luteous (11).

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

Conidiophores mononematous, unbranched or dichotomously branched, hyaline, coarsely roughened, 2.5-3 mm diam, with 1-3 conidiogenous cells arising from each terminus.

Conidiogenous cells clavate, hyaline, roughened, 10-20 x 3-5 mm. Conidia produced from percurrently proliferating conidiogenous cells or, infrequently, from sympodially proliferating conidiogenous cells.

Conidia hyaline, smooth, subglobose to obovoid, usually with an attenuated flattened base, (5.5-) 7-9 x (4.5-) 5-6 (-7) mm.
