Updated taxonomy on (Porotheleaceae, Agaricales) with three new taxa and one new record from China.

Only three (Porotheleaceae) species have been previously recorded in China. Here, we report collections of a fourth species in China: Har. Takah., which is widely distributed in Chinese temperate to subtropical zones. We also formally describe three new species, collected from Anhui, Fujian, and Zhejiang provinces: , , and Furthermore, we include the results of a phylogenetic analysis of Porotheleaceae based on a multi-locus (ITS + nLSU) dataset. The results, which indicate that is polyphyletic, support the taxonomic recognition of the three new species. Morphological descriptions, photographs, line drawings, and comparisons with closely related taxa are presented for the new and newly recorded species. A key to the seven species of in China is also provided.
