RESUMO
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-1α) 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.
RESUMO
En este estudio se citan las diferentes especies del género Cantharellus que se han encontrado en Guatemala desde hace ya algunas décadas así como los resultados de análisis microscópicos obtenidos de siete especies particulares que fructifican en Guatemala: Cantharellus lateritius, C. cibarius, C. atrolilacinus, C. cinnabarinus, Craterellus ignicolor, C.tubaeformis y C. calyculus, con el fin de determinar si existen diferencias en las medidas reportadas en Europa o Norteamérica, donde han sido descritas la mayor parte de las especies de este importante género...
