sometimes interrupted, becoming yellowish with age; perithecia minute, ovoid, immersed 
with the necks protruding, numerous, pale-yellow, becoming darker with age; ascicylindric; 
spores l-seriate with ends overlapping, fusiform but not apiculate, straight or a little curved

Stromata consisting of an effuse cottony subiculum often of considerable extent (rarely 
subpatellate and subfleshy), occurring as a parasite on fleshy fungi or more rarely on old 
wood, rotten leaf-mould and other substrata where there is no trace of other fungi ; conidial 
phase variable, represented by species of Sepedonium, Verticillium, Trichothectum, Dac- 
tylium, etc.; perithecia numerous, usually thickly scattered and immersed in the subiculum, 
rarely subsuperficial or with the necks more or less protruding ; asci cylindric, 8-spored ; 
spores fusoid or fusiform, usually with an apiculus at each end or ends obtuse, 1-septate 
hyaline, smooth or rough.
