Description

Saprobic on leaf of Arenga tremula (Arecaceae). Sexual morph: not observed. Asexual morph: Conidiomata 200–330 µm length × 140–190 µm diam. (x =250 × 160 µm, n=10), pycnidial, semi-immersed, solitary, globose, unilocular, black dots, a crack on the surface of the host where the conidiomata is located. Peridium 20–30 µm (x =21 µm, n=5), composed of thick-walled, brown-black cells of textura angularis, thin inner wall, almost reduced to conidiogenesis region. Conidiophores reduced to conidogenous cells. Conidiogenous cells hyaline, holoblastic, rough. Conidia 10–30 µm × 10–15 µm (x =21 × 11 µm, n=40), hyaline, subglobose to ellipsoid, aseptate, granular content, one to two large guttules, broadly rounded at both ends, thin-wall without mucilaginous.

 

Culture conditions: colonies on PDA reach 7 cm diam. at 28˚C after five days.
