, and revisited - New species and generic reclassification.

Molecular phylogenetic analyses of a multigene matrix of partial nuSSU-ITS-LSU rDNA, and sequences were performed to investigate the phylogenetic relationships of , and species. Based on phylogenetic analyses and morphology, the genus is synonymised with , and the genus is revealed as polyphyletic. is confirmed to be closely related to the generic type and its morphology is described and illustrated. , , , and are recognised in , and and are combined in . Based on pure culture studies and DNA sequence data, and are shown to be the sexual morphs of and , respectively. European accessions of are recognised to differ from the North American type and are described as . The sexual morph of is recorded and described for the first time. The generic type of , , is epitypified with a recent collection from the type host, . Based on sequence data, is recognised as a distinct species. Several species for which subperidermal stromata have been reported are shown to be fungicolous on , the "stromata" representing aborted and transformed host stromata or conidiomata: , , and on spp.; on conidiomata of ; on conidiomata of sp.; and on . The newly described is fungicolous on cf. ().
