Abstract

Phylloporia species are characterized by having annual to perennial, with resupinate, pileate-sessile to pileate-stipitate basidiomata, and duplex context. They have monomitic to dimitic hyphal system, basidiospores are globose to cylindrical, thick-walled, yellowish to pale brown in KOH. The genus includes 72 species described worldwide, and only eight taxa have been recorded in Mexico, five of which have been molecularly characterized. The objective of this study is to describe and illustrate two new stipitate species of Phylloporia from the Chamela Biology Station located in the municipality of La Huerta in the state of Jalisco, Mexico: P. rajchenbergii and P. ryvardenii. For this, the specimens were reviewed in detail in order to describe their macroscopic and microscopic characteristics, DNA extraction was performed and the 28S rDNA (LSU) was amplified by PCR. Phylogenetic analyzes were performed using Bayesian Inference and Maximum Likelihood methods. It is corroborated that Phylloporia rajchenbergii and P. ryvardenii differ from the species described in the genus due to the color of the pileus, the size of the pores, the type of context (homogeneous in P. ryvardenii) and the size of the basidiospores; in addition, both species form different clades in the phylogenetic analyzes carried out.
