Abstract

To determine if can accumulate diverse pathogens from surrounding native plants, we intensively sampled fungal communities, including endophytes, leaf spot pathogens and canopy air fungi, associated with as well as native plants in its invasive range. In total, we collected 4542 foliar fungal strains from 10 geographic sites, including 1340 from healthy leaves of , 2051 from leaf spots of and 1151 from leaf spots of 56 species of native plants and crops. Taxonomically, the common fungal genera included , , , , , , , , , , , and . We also isolated the cultivable fungi from 12 air samples collected from six areas in Yunnan Province, PR China. Among the total of 1255 air fungal isolates, the most common genera were , and . Among them, two new species, from leaf spot of and from canopy air of were found. The two species showed both asexual and sexual reproductive structures. The conidia of and are larger than those of and . The size of ascospores of and also differ from . Phylogenetic analysis of the combined ITS, LSU rRNA, and sequences showed that and each formed a distinct clade, separated from all species previously described in and confirmed them as new species belonging to . Full descriptions of are provided in this study.
