Observations on Pluteaceae in Vietnam: Four New Species and New Records of Pluteus

J Fungi (Basel). 2023 May 18;9(5):584. doi: 10.3390/jof9050584.

Abstract

Eighteen specimens of Pluteus collected from the tropical forests of Vietnam were studied using morphological and molecular approaches. Pluteus podospilloides, P. semibulbosus, P. chrysaegis and P. septocystidiatus are registered as additional or new records for Vietnam. Four species (P. conformis, P. lucidus, P. subroseus, and P. ornatus) are proposed as new to science, and several other collections (Pluteus sp. 1, P. aff. septocystidiatus, P. aff. pauperculus and P. cf. velutinus) are given an inconclusive taxonomic status for now. The taxonomic positions of all specimens were confirmed using DNA data (nrITS and tef1). Descriptions of the macro- and microscopic features of the studied collections with a discussion of similar taxa are given.

Keywords: Agaricales; Basidiomycota; molecular phylogeny; new species; nrITS; taxonomy; tef1.
