Ascoma a uniloculate, perithecioid pseudothecium, immersed in host tissue, separate or clustered, with erumpent ostiolar papilla, often with setae around ostiole. Ascomal wall composed of brown, somewhat thick-walled pseudoparenchyma cells, inner wall cells hyaline and thin-walled. Centrum with filamentous, branched, septate, pseudoparaphyses. Asci bitunicate, cylindrical or oblong, short-stalked, 8-spored. Ascospores oblong, elliptical, clavate, or fusoid, olive-green to pale or dark brown, smooth or roughened, sometimes with a thin gelatinous sheath, septate at, above, or below the middle, constricted or not at the septum. (Fig. 7D-F).
Anamorphs: Cladosporium, Fusicladium, Pollaccia, and Spilocaea.
Habitat: Parasitic on living plant tissues, usually leaves, causing diseases, with ascomata of some species maturing in overwintered leaves.
