SUMMARY:

Gasteroid fungi are primarily characterized by angiocarpic development (within a closed hymenophore) with the absence of a hilar appendage, necessitating the passive dispersion of their basidiospores during the maturation stage. These organisms represent a polyphyletic category within the Phylum Basidiomycota and share homoplastic morphological adaptations. Being a non-monophyletic group, species cataloging data are often diluted in publications by genera, or at best, by families. In Brazil, 232 species are documented, with around 50 of these in the Northeast region, predominantly in the Atlantic Forest. The present study aimed to assess and enhance knowledge regarding the taxonomic diversity of gasteroid fungi in Cerrado areas in Western Bahia, a region that remains largely unexplored with limited species records, in order to acquire biodiversity data essential for the conservation and preservation of the studied conservation units. Collections were conducted in two municipalities within the Intermediate Geographic Region of Barreiras, Western Bahia: São Desidério and Barreiras. Three significant areas with distinct phytophysiognomies were chosen for the Cerrado in Western Bahia: the Rio de Janeiro Basin Environmental Protection Area, situated between the municipalities of Luís Eduardo Magalhães and Barreiras, covering an area of 351,300 ha; the São Desidério Environmental Protection Area, located in the municipality of São Desidério, spanning an area of 10,961.14 ha; and the Rio de Ondas Hydrographic Basin, which traverses the municipalities of Barreiras and Luis Eduardo Magalhães, encompassing an area of 5,857 km². In total, 30 species were described, distributed across 10 genera and five families. For the Cerrado biome, 24 taxa were documented for the first time, an increase of approximately 35%, with four new records of second occurrence. The study unveiled 11 species new to science, all corroborated by morphological data, of which three were additionally validated by molecular data.
