Description

Conidiomata 395–425 µm diam, pycnidial in culture on PDA, globose to clavate, solitary or aggregate, black, semi-immersed, ostiole in the center; releasing conidia in a black, slimy, globose, glistening mass. Conidiophores sparsely septate at base, hyaline, subrotund to irregular, branched or unbranched, up to 15.5 µm. Conidiogenous cells 4 × 2 µm, discrete, smooth-walled, hyaline, ampulliform to subcylindrical. Conidia 17.5–22 × 5.5–7 µm (x̅ ± SD = 20 ± 1.3 × 6 ± 0.5 µm, n = 40), fusiform to ellipsoid, 4-septate, straight to slightly curved, slightly constricted at septa; basal cell 3.5–5 µm long, conic with a truncate base, hyaline, sparsely verruculose and thin-walled; three median cells 10–13 µm long, x̅ ± SD = 12 ± 1 µm, doliiform, verruculose, concolourous, maple, septa darker than the rest of the cell (second cell from the base 4–5 µm; third cell 3.5–4.5 µm; fourth cell 4–5 µm); apical cell 3.5–5 µm long, hyaline, sparsely verruculose, conical to subcylindrical, thin- or smooth-walled; apical appendages 9–28 µm long, x̅ ± SD = 16.5 ± 4.3 µm, 1–3 (seldom 1), tubular, arising from the apical crest, unbranched, filiform; basal appendage 2.5–6 µm long, single, tubular, unbranched, centric.

 

Culture conditions: Colonies on PDA attaining 5 cm diam after 7 d at 25 ˚C, circular, flat, curled, rough, white, undulate; reverse cream.
