Abstract:The lichen genus Coenogonium belongs to Coenogoniaceae, Ostropales, Ostropomycetidae, Lecano- romycetes, Ascomycota, Fungi, mainly distributed in tropics and subtropics. Ten species of Coenogonium were reported, including a species, C. disjunctum, as new record to China. Each species is described and discussed in detail, and the key to the genus and the photos of the new record species are presented. It is the first systematic study on Chinese Coenogonium, which can provide the basic information for the taxonomy of lichenized fungi.
