The current knowledge of the lignicolous genus Heteroradulum was clarified for the Czech Republic. The occurrences of both European species, Heteroradulum deglubens and H. kmetii, are based on field collections and herbarium specimens. Heteroradulum deglubens was collected on dead hardwoods in near-natural forests and its identity was confirmed by DNA sequences of the ITS region. Heteroradulum kmetii was collected in warmer parts of the Czech Republic only and differs from H. deglubens in its ecology. An extended host tree spectrum is confirmed for both species.
