Fan & C.M. Tian, Persoonia 40: 124 (2018) Type species. Dendrostoma mali X.L. Fan & C.M. Tian, Persoonia 40: 124 (2018). Notes. Dendrostoma was introduced by Fan et al. (2018a) as a phytopathogenic genus, causing canker diseases on several economic hardwoods such as Malus spectabilis , Osmanthus fragrans and Quercus acutissima . Jiang et al. (2019b) accepted 14 species of Dendrostoma using a concatenated matrix of four genes (ITS, LSU, rpb2 and tef1-α ), including 10 new species associated with chestnut and oak canker disease in China. Here we recommend a set of three genes (ITS, rpb2 and tef1-α ) to separate species of this genus.
