Taxonomía y filogenia del género Fomitiporia Murrill (Hymenochaetales, Basidiomycota) en México
The genus Fomitiporia was described by Murrill (1907) and included 17 species with basidiomata perennial and resupinate, hymenophore poroid, context brown color and the basidiospores globoses and hyaline. This genus was considered as a synonym of Fomes, Poria or Phellinus, however, today, several au...

| Sumario: | The genus Fomitiporia was described by Murrill (1907) and included 17 species with basidiomata perennial and resupinate, hymenophore poroid, context brown color and the basidiospores globoses and hyaline. This genus was considered as a synonym of Fomes, Poria or Phellinus, however, today, several authors have confirmed the delimitation of the genus, adding characters as basidioma pileate, the presence or absence of hymenial setae, cistidioles and basidiospores dextrinoide in Melzer's reagent and cianophilous in cotton blue. The species produce decay wood, causing white rot and some species are considered as forest pathogens. Actually, 34 species have been described in the world. In Mexico, only are cited Fomitiporia hartigii, F. punctata and F. robusta. The main objective of this paper is analyze the morphological and molecular characters of the species of the genus Fomitiporia that grow in México, for a better understanding of taxonomic, phylogenetic, ecological and geographical relationships among species of this group. At the present study, a bibliographical review of the original descriptions of the species of Fomitiporia was realized, placing the Herbaria where the type specimens are deposited. Several collections of specimens in arid, semiarid, temperate and tropical Mexico were made. The specimens were isolated in culture medium of Malt Extract Agar to 2%.Some specimens were amplified and sequenced in four independent genes nLSU, ITS, Tef1α and RPB2. The phylogenetic reconstruction was performed by maximum parsimony and bayesian inference. The phylogenetic and morphological studies revealed the presence of F. apiahyna, F. calkinsii, F. dryophila, F. hartigii, F. langloisii, F. maxonii, F. sonorae and F. texana. F. baccharidis is proposed as a new combination, while, F. cupressicola, F. duranguensis, and F. intermedia are proposed as new species for the science. Of the species studied, 50% have tropical affinity and 50% have temperate affinity, however, it is assumed that in the tropical area there are a greater number of endemic species, whereas temperate species have specific affinity for the host.
