Four graminicolous fissitunicate ascomycetes, Phaeosphaeria (Pha.) oryzae, Pha. nigrans, Pha. donacina, and Paraphaeosphaeria michotii, are redescribed with reference to the anatomy of ascomata, asci, and pseudoparaphyses and the external morphology of ascospores. Phaeosphaeria donacina is new to Japan. Phaeosphaeria oryzae is the second record from Japan. These ascomycetes were isolated from the healthy prime leaves of two reed species, Phragmites (Phr) australis and Phr. karka, collected in Osaka Prefecture, central Japan, from 1995 to 1998.
