Xerocomellus perezmorenoi (Boletaceae, Boletales), a new edible species from Mexico

Abstract

Xerocomellus perezmorenoi (Boletaceae, Boletales) is described as a new species from Mexico. This species was collected under Abies religiosa in mixed coniferous forest located in three localities (Puebla, Tlaxcala, and State of Mexico) in central Mexico. It is morphologically characterized by its small-sized basidiomata, pileus brown at the center and cream with pink to purple tones at the margin, almost blackish at the center when young, black-brown when mature, pores lilac, peach to salmon when young, yellow citrine at mature; violet or violet-brown color reaction of the context when cut; basidiospores (12–) 15–16 (–17) × 4–5 (–6) µm. Phylogenetic analyses (Maximum likelihood and Bayesian inference) based on multi-locus sequences confirmed X. perezmorenoi is a new species, with biocultural importance due to edibility. Detailed a description, photographs, analyses of phylogenetics, and taxonomic discussions are presented.
