摘要
During explorations of tropical oak forests in central Veracruz (eastern Mexico), the authors discovered a Cantharellus species that produces basidiomes with strikingly violet pileus and a hymenium with yellow, raised gill-like folds. It is harvested locally and valued as a prized edible wild mushroom. Systematic multiyear sampling of basidiomes allowed the recording of the morphological variation exhibited by fresh fruit bodies in different growth stages, which supports the recognition of this Cantharellus species from others in the genus. Two molecular phylogenetic analyses based on a set of sequences of species of all major clades in Cantharellus, one including sequences of the transcription elongation factor 1-alpha (tef-1 alpha) and a combined tef-1 alpha and nLSU region (the large subunit of the ribosome), confirm the isolated position of the new species in a clade close to C. lewisii from USA, in the subgenus Cantharellus. Detailed macroscopic and microscopic descriptions, accompanied by illustrations and a taxonomic discussion are presented.
