Two new species and a new record of yellow Cantharellus from tropical Quercus forests in eastern Mexico with the proposal of a new name for the replacement of Craterellus confluens

Two new species of yellow Cantharellus and a new record of Cantharellus tabernensis associated with tropical species of Quercus are presented, based on the taxonomic study of fresh specimens and in a phylogenetic analysis of transcription elongation factor 1-alpha (tef-1 alpha) and the large subunit of the ribosome (nLSU) sequences. One of the new species proposed here, corresponds to a choice edible mushroom, which, in our molecular phylogeny, resulted in it being related to the group of species around C. lateritius and sister with Craterellus confluens type specimen. This latter is here formally transferred to Cantharellus and consequently a new name, Cantharellus furcatus, is proposed to replace the homonym Cantharellus confluens (Schwein.) Schwein. 1834 a later synonym of Byssomerulius corium. Detailed macroscopic and microscopic descriptions accompanied with illustrations and a taxonomic discussion are presented for each species.

Automated summary

Two new species of yellow Cantharellus and a new record of Cantharellus tabernensis associated with tropical species of Quercus are presented, based on taxonomic study and phylogenetic analysis. A new species, Cantharellus furcatus, is proposed as a replacement for a homonym species.
