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 wk, whitish, felty, azonate, with diffuse margins, becoming funiculose; reverse uncolored.

Stromata confluent, distributed at edge of colony, pulvinate, gray.

Sporulating regions at edge of colony, commonly on stromatal surface and less frequently on mycelial surface, hazel (88).

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

Conidiophores mononematous, di- or trichotomously branched, sometimes with additional branches arising from the first level of conidiogenous regions, hyaline to yellowish, coarsely roughened, 2.5-3 mm diam, with two to three conidiogenous cells arising from each terminus.

Conidiogenous cells cylindrical, hyaline, roughened, 10-17 x 2-3 mm. Conidia produced holoblastically in sympodial sequence.

Conidia hyaline, smooth, ellipsoid, with flattened base, 4.5-6.5 x 2.8-3.2 mm.

Teleomorph produced in stromata in 6-8 wk, with morphological features as described for naturally-occurring material.
