Ascomicetos assexuais associados a serapilheira terrestre e submersa no brejo paraibano

Abstract

The Atlantic Forest is a priority biome for conservation due to its high biodiversity and high degree of degradation. The Brejo Paraibano, a humid enclave in this biome, harbors a fungal diversity that has not yet been studied, despite its essential role in ecological processes. This study aimed to identify asexual fungi associated with in terrestrial and aquatic environments in the Brejo Paraibano, contributing to the knowledge of the regional mycobiota. Permanent slides of saprobic fungi collected between 2019 and 2022 in the Mata Pau-Ferro Ecological Reserve and Sítio Jardim, in the municipality of Areia, and in Cachoeira da Manga, in Pilões, were analyzed,

obtained from direct observation of the plant substrates in a humid chamber. Twenty- one taxa, distributed in 21 genera, were identified based on classical taxonomy,

including six new records for Paraíba (Circinotrichum maculiforme, Dendryphiopsis atra, Dictyosporium elegans, Satchmopsis pini, Thozetella buxifolia and Xenosporium berkeleyi), two first records for the American continent (Gliocladiopsis pseudotenuis and Neohelicosporium guangxiense) and a possible new species belonging to the genus Paratetraploa. The results demonstrate the relevance of Brejo Paraibano as an area of high fungal diversity and reinforce the need for taxonomic studies in the region.
