Two new species of Chroogomphus (Gomphidiaceae, Boletales) with biocultural importance in the Tlahuica-Pjiekakjoo culture from Central Mexico

The genus Chroogomphus has scarcely been studied in Mexico, with only one species reported in the country despite its great biocultural importance in native cultures. In this study, two new species of Chroogomphus are presented based on genetic and morphological characterization. The phylogenetic analysis with DNA sequences from nrITS region confirmed that C. conacytiensis sp. nov. and C. flavovinaceus sp. nov. are included in independent clades separated from other species within the subgenus Chroogomphus. Both species have great biocultural importance in the Tlahuica-Pjiekakjoo native culture from Central Mexico as edible taxa, and are associated with Pinus pseudostrobus in Quercus-Pinus and in Pinus hartwegii forests. Descriptions and photographs of the newly described species are presented.

Automated summary

In this study, two new species of the genus Chroogomphus were described based on genetic and morphological characteristics. The phylogenetic analysis confirmed that these two species, C. conacytiensis sp. nov. and C. flavovinaceus sp. nov., form separate clades from other species within the subgenus Chroogomphus. These species have great biocultural importance in the native culture of Tlahuica-Pjiekakjoo in Central Mexico, serving as edible taxa and being associated with Pinus pseudostrobus in Quercus-Pinus and Pinus hartwegii forests. Descriptions and photographs of the newly described species are provided.
