In type of thallus, size of its cells, and in the possession of pycnidia only, does this differ from all others of the Trichopeltaceae. The conidia resemble those of T. hydycaryae Th. but the thallus does not agree with that species. 62. TRICHOTHALLUS Stevens n. gen. Thallus of the Trichopeltaceae. No perithecia or pycnidia present.
