Reassessment of and Four New Species of from Olive () in Sichuan Province, China.

species are saprobes on decaying wood in terrestrial, mangrove, and freshwater habitats. The generic boundary of the family has traditionally been based on morphology. All genera of have a high degree of morphological overlap, of which the generic circumscription of and has not been well resolved. Thus, the delimitation of genera has always been challenging. traditionally differs from in having 2-septate, oblong, with obtuse-ends ascospores. These main characteristics have been used to distinguish from for a long time. However, the above characteristics sometimes overlap among and species. Based on the morphology and multigene phylogeny with newly obtained data, we synonymized under following up-to-date results. Four novel species (i.e., , , and ) collected from the dead branches of L. in Chengdu Olive Base, Sichuan Province in China are introduced based on detailed morphological characterization and phylogenetic analyses of sequences based on nuclear ribosomal (LSU and SSU) and protein-coding gene (). The 11 new combinations proposed are (=), (=), (=), (=), (=), (=), (=), (=), (=), (=) and =.
