Four new species of Acomycetes, Ascotaiwania pennisetarum sp. nov., Diaporthe appendiculata sp. nov., Diaporthe minutis sp. nov., and Oxydothis miscanthiecola sp. nov., are described from senescent culms of grasses in Hong Kong. Ascotaiwania pennisetarum is distinctive from other species in the genus as ascospores are narrower. Diaporthe minutis differs from the most similar Diaporthe species in having ascospores with bipolar mucilaginous pads, while Diaporthe appendiculata differs from other species in having ascospores with both a mucilaginous pad and appendages at both ends. Oxydothis miscanthiecola differs from other species in the genus in having long fusiform ascospores, which taper to rounded apices or otherwise differ in shape and size. These new species are compared with existing species and illustrated with interference light micrographs. The Diaporthe species known to possess mucilaginous ascospore appendages are listed
