Taxonomy and Phylogeny of Cystolepiota (Agaricaceae, Agaricales): New Species, New Combinations and Notes on the C. seminuda Complex.

ABSTRACT: Species of Cystolepiota are known as diminutive lepiotaceous fungi with a worldwide distribution. Previous studies revealed that Cystolepiota is not monophyletic and preliminary DNA sequence data from recent collections suggested that several new species exist. Based on multi-locus DNA sequence data (the nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2, ITS; the D1-D2 domains of nuc 28S rDNA, LSU; the most variable region of the second-largest subunit of RNA polymerase II, rpb2 and a portion of the translation-elongation factor 1-α. tef1), C. sect. Pulverolepiota forms a distinct clade separating from Cystolepiota. Therefore, the genus Pulverolepiota was resurrected and two combinations, P. oliveirae and P. petasif
