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 wk, whitish, felty, azonate, with diffuse margins, becoming buff (45) with sporulation; reverse citrine (13).

Sporulating regions scattered over entire surface of colony.

Conidiophores mononematous, dichotomously branched, hyaline, smooth or finely roughened, with intercalary coil-like twists at various lengths, 2.5-4 µm diam, with one conidiogenous cells arising from each terminus.

Conidiogenous cells cylindrical, hyaline, smooth, 10-20 x 2.5-3.5 µm. Conidia produced from percurrently proliferating conidiogenous cells.

Conidia hyaline, smooth, ellipsoid, with flattened base, 5.5-8 x 3.5-4.5 µm.

Teleomorph produced in stromata in 8-10 wk, homothallic, with morphological features as described for naturally-occurring material.
