Mycol. 26: 248, 1928 (Fig. 36).Colonies amphigenous, mostly epiphyllous, dense,scattered, up to 2mm in diameter, confluent. Hyphaeundulate to tortuous, branching alternate to oppositeat acute to wide angles, loosely reticulate, cells 18–24x4–6 µm. Appressoria alternate to unilateral, straightto curved, antrorse to reflexed, 14–18 µm long; stalkcells cylindrical to cuneate, 6–8 µm long; head cellsovate, globose, entire, 8–10x6–8 µm. Phialides mixedwith appressoria, scattered, opposite to alternate,ampulliform, 14–18 µm, occasionally tip twisted. Mycelialsetae very few, grouped around perithecia, simple,acute to obtuse at the tip, up to 207µm long. Peritheciagrouped, verrucose, up to 130µm in diam.; ascosporesobovoidal, 4-septate, constricted, 30–34x12–14 µm.Material examined: 6.viii.2008, on leaves ofClerodendrum infortunatum L.
