Description
Saprobic on rachides and leaves of palms. Sexual morph Undetermined. Asexual morph
Hyphomycetous. Colonies scattered, granular, black, glistening, punctiform distributed on the substrate. Mycelium mostly immersed in the substrate, composed of branched, septate, subhyaline to pale brown, smooth hyphae. Conidiophores semi-macronematous, reduced to conidiogenous cells, subhyaline to pale brown, smooth, thin-walled. Conidiogenous cells 0.7–1.2 μm, integrated, determinate, holoblastic, monoblastic, terminal, cylindrical, subhyaline to pale brown. Conidia (14–)18–34 × (8.5–)12−22 (x̅ = 24.6 × 17.7 μm, n = 30), acrogenous, solitary, globose to broadly ellipsoidal, muriform, brown and hyaline immature, thick-walled. The number of cells per conidium varies from 10–30, apical row with 1−3 cells.
Culture conditions: colonies on MEA reach a diam. of 20mm after three weeks at 25–28˚C.
