Species Diversity, Distribution, and Phylogeny of with the Addition of Four New Species from Thailand.

The genus is an anamorphic ascomycete fungus in the family of the order . species have been classified as polymorphic black yeast-like fungi. Prior to this study, 63 species had been validated, published, and accepted into this genus. species are known to be distributed worldwide and have been isolated in various habitats around the world. Several species have been identified as potential agents of human and animal mycoses. However, in some studies, species have been used in agriculture and biotechnological applications. Here, we provide a brief review of the diversity, distribution, and taxonomy of through an overview of the recently published literature. Moreover, four new species were isolated from rocks that were collected from natural forests located in northern Thailand. Herein, we introduce these species as , , , and . The identification of these species was based on a combination of morphological characteristics and molecular analyses. Multi-gene phylogenetic analyses of a combination of the internal transcribed spacer (ITS) and small subunit (nrSSU) of ribosomal DNA, along with the translation elongation factor (), partial β-tubulin (), and actin () genes support that these four new species are distinct from previously known species of . A full description, illustrations, and a phylogenetic tree showing the position of four new species are provided.
