Descrição: Brazil harbours a unique ecosystem, the Caatinga, which belongs to the tropical dry forest biome. This region has an important diversity of organisms, and recently several new fungal species have been described from different hosts and substrates within it. During a survey of fungal endophyte diversity from cacti in this forest, we isolated cladosporium-like fungi that were subjected to morphological and multigene phylogenetic analyses including , ITS, LSU, and gene sequences. Based on these analyses we identified two new species belonging to the genus , described here as and spp. nov., isolated from subsp. and , respectively. To improve the species recognition and assess species diversity in we studied all ex-type strains of the genus, for which , and barcodes were also generated. After phylogenetic reconstruction using five loci, we differentiated 13 species in the genus. and are synonymized based on their phylogenetic position and limited number of unique nucleotide differences....
