Abstract

The kingdom Fungi is known for having a high diversity, corresponding to one of the largest groups of living organisms. Nevertheless, it is estimated that only about 5% of the existing species have been described. The class Agaricomycetes groups a large part of the macroscopic fungi, including the order Polyporales, which is divided into four major clades. The residual polyporoid clade groups species with highly variable morphology, with hymenophore formed by pores, teeth, smooth or other intermediate settings. Although they present quite variable macro and micromorphology, all species in the group cause white rot. In the current phylogenies, the residual polyporoid clade is not well resolved and even though at least five families have been recognized in the group there is no support to confirm the validity of these. Recent studies have also shown that many of the genera included in the clade are polyphyletic and more analyses are needed to solve the classification of the species on a generic level. Moreover, few Neotropical species were included in these studies and the affect of adding them to phylogenetic analyses of the clade is not known. This project aims the morphological study and evaluation of the phylogenetic position of species and genera of the residual clade poliporoid in Brazil, with emphasis on poroid species. Molecular analyses including four markers (ITS, LSU, tef1-± e rpb2) and macro and micromorphological studies of the species collected will be performed. With this, will be possible to establish taxonomical characteristics for the identification and diagnosis of genera, describe possible new species and add new records to Brazil. The results of the phylogenetic studies will allow the analysis of the stability of the clade and assist in understanding the evolutionary relationships of the genera in the group. (AU)
