Based on a recent investigation of species of the Rhytismatales in the eastern Himalayas in China, two species of Lirula on Abies were found, one of which is described as a new species, Lirula yunnanensis, which differs from Lirula japonica mainly by ascomatal structure and conidiomatal features, while the other is Lirula exigua, a new record for China. An analysis of the combined sequences of ITS + LSU r DNA showed that Lirula macrospora and Lophodermium piceae were closely related and that Lirula yunnanensis and Lophodermium autumnale were grouped together. The genus of Lirula should be redefined based on more molecular data. Lirula exigua was distantly related to Lirula species and its systematic position has to be confirmed by further molecular data. A key for known species of Lirula worldwide is provided.
