Six genera of the order Pleosporales are revised taxonomically. Although five genera have unusual applanate ascospores, they are members of three different families. Clathrospora(10 species, 2 new), Comoclathris(21 species, 7 new), and Macrospora(3 species) are placed in a new family Diademaceaein which the ascoma opening is a characteristic flat circular lid. Diademosa, a new genus with one species with terete ascospores is placed in Diademaceae. Graphyllium(3 species) is placed in the family Hysteriaceae characterized by hysterothecia with a slit-like opening. Platysporoidesn.gen. (11 species, 1 new) is maintained in the Pleosporaceae because of the terete pored beak of the ascomata. Key words: Pleosporales, applanate ascospores, Clathrospora, Comoclathris, Macrospora, Diademosa, Graphyllium, Platysporoides. |
