SUMMARY:

This thesis aims to expand the taxonomic and phylogenetic knowledge of two clades within the suborder Tricholomatineae (Agaricales), specifically Rhodocybe–Clitopilus (Entolomataceae) and Asproinocybe–Tricholosporum (Lyophyllaceae), in Brazil. The study adopts an integrative taxonomic approach, combining detailed morphological analyses — using light microscopy and scanning electron microscopy (SEM) — with molecular data based on ITS, LSU, RPB2, and TEF1 sequences. Field collections were carried out in various regions of the country, including areas of the Atlantic Forest, Amazon, and Cerrado. In addition, specimens from fungal collections were also examined. Molecular analyses include DNA extraction, PCR amplification, sequencing, and phylogenetic inference using maximum likelihood and Bayesian methods. This research is expected to clarify the evolutionary relationships among the studied groups, describe new species, and contribute to the understanding of fungal diversity in Brazil.
