A review of the taxonomy and species diversity in Dacrymycetes (Fungi, Basidiomycota) in Mexico
Castro-Santiuste, Sandra; Sierra, Sigfrido; Guzmán-Dávalos, Laura; Luna-Vega, Isolda
The class Dacrymycetes has been considered a monophyletic group based on shared morphological characteristics and recent molecular studies, with bifurcate basidia and non perforate parenthosome as synapomorphies. In this review of the state of knowledge for Dacrymycetes (dacrymycetoid fungi) in Mexico, a detailed survey of the literature revealed 21 species in eight genera in Mexico; 20 belong to seven genera of Dacrymycetaceae and one species belongs to the Cerinomycetaceae. The best-represented genus is Dacrymyces, and the most-recorded species is Dacryopinax spathularia. Taxa of Dacrymycetes in Mexico have been recorded from 22 states, mainly those located in central Mexico. The members of this group recorded in Mexico are, apparently, wood-decomposers and have been most frequently collected during the wet season (end of May to beginning of October), but they can be found throughout the year. From the review, it is evident that systematic and biogeographic knowledge on the Dacrymycetes in Mexico is scarce. Thus, more extensive sampling and detailed systematic and molecular studies are needed.
