Ommatomyces, with one new species and one new combination

Abstract

A new species of Ommatomyces is described from senescent culms of Pennisetum purpureum and Thysanolaena maxima collected in Hong Kong. Didymosphaeria pardalina may be an earlier name for Ommatomyces coronatus, however there are several differences between this species and O. coronatus. Until further collections are made we maintain O. coronatus and combine Didymosphaeria pardalina as a third species of Ommatomyces, One of the most important characters of Ommatomyces is the short lacerate germ slits that occur at each end of ascospore and separates it from Cainia species.
