Abstract
Two new form-genera of the Fungi Imperfecti, Sphaeropsidales are described. Idiocercus n. gen. is characterized by punctiform, unilocular, pycnidia, annellophores and hyaline, aseptate conidia with an elongated basal frill, and contains two species: I. pirozynskii n. sp. (type species) and I. macarangae (T. S. Ramakrishnan) n. comb. Bellulicauda n. gen. is based on a single species, B. dialii (Syd.) n. comb., and features lacunose stromata, annellophores, and pale brown, aseptate conidia with an elongated basal frill. Idiocercus and Bellulicauda are compared and contrasted with Diachorella, Plagiorhabdus, and Strasseria, genera which are shown to produce appendaged phialospores. Plagiorhabdus is tentatively reduced to synonymy with Strasseria.
