Checklist de homobasidiomicetos corticioides (Agaricomycetes, Basidiomycota) no Estado de São Paulo

Abstract

Currently, the world diversity of fungi is estimated between 2.2 and 5.1 million species. However, only around 144 thousand species are known. Fungi are essential for the maintenance of most ecosystems as they are among the main participants in nutrient cycling, contributing to ecological succession. In addition, many species have biotechnological potential. The homobasidiomycete corticioid fungi (Agaricomycetes, Agaricomycotina) are defined by presenting reproductive structures in resupinate to stipitate basidiomes, and a hymenal surface ranging from smooth, folded, tuberculate, spiny, toothed or, more rarely, poroid. Although corticioid fungi are historically inserted in Aphyllophorales Rea, and also often referred to as Corticiaceae Herter, it is already known that these organisms constitute an artificial group with diverse phylogenetic origins. Despite the increase of scientific production related to corticoid fungi, many new taxa have been described and several regions of the State of São Paulo remain underexplored. Therefore, the present work aimed to contribute to the knowledge of corticioid fungi in the State of São Paulo, through a checklist of species based on literature. All taxa that occur in the State of São Paulo were listed, along with information such as the Municipality, biome, river basin and domain in which they were found. A total of 149 species were listed for the State of São Paulo, distributed in 63 genera, 35 families and 11 orders. The order with most representatives was Polyporales, with seven families. The family with the most genera found (eight) was Peniophoraceae. The results of this Checklist represent an important contribution to the development of knowledge about corticioid fungi in the State of São Paulo, and highlights that there are still gaps in knowledge for some regions of the State that remain underexplored.
