CULTURES AND ANAMORPH

Colonies on OMA reaching the edge of Petri dish in 3 wk, whitish, velvety, with diffuse margins, becoming Honey (64) to Hazel (88), zonate. Reverse Greenish Olivaceous (90), becoming Umber (9). Sporulating regions scattered over entire surface of colony, sparse, Honey (64). Conidiogenous structure with Nodulisporium-like branching pattern as defined in Ju and Rogers (1996). Conidiophores pale brown, roughened, dichotomously branched, sometimes with additional branches arising from the first level of conidiogenous regions, 3-3.5 µm diam, with 3-6 conidiogenous cells arising from each terminus. Conidiogenous cells cylindrical, hyaline, smooth or finely roughened, 6-15 x 2-3 µm, bearing one to several poroid conidial secession scars on apical region. Conidia produced holoblastically in sympodial sequence, hyaline, smooth, obovate to ellipsoid, 4-5.5 x 2-3 µm, with flattened base indicating former point of attachment to conidiogenous cell.
