The perithecia are immersed in the substratum, the ostiole onlyprojecting, but they may become more or less exposed by the rupture of thecovering tissues. The peridium is leathery or membranous. The genus Pleospora includes some 225 species, several of which occuron grains and other grasses where they show biological specialization.Pleospora kerbarum is a facultative parasite on the leaves of angiosperms ;the perithecium is initiated by the division of a hypha into
