During our investigation of saprobic fungi in southwestern China, three micro-hyphomycetous were isolated from dead wood freshwater and terrestrial habitats Guizhou Province. Phylogenetic analyses ITS, LSU, SSU sequences, performed using Maximum Likelihood Bayesian Inference methods, confirmed that these isolates belong to Kirschsteiniothelia . Based on distinct morphological characteristics molecular phylogenetic evidence, we describe new species: guizhouensis , K. weiningensis xishuiensis Furthermore, the effectiveness DNA markers for species-level identification within was evaluated Assemble Species by Automatic Partitioning (ASAP) analysis, which identified ITS nucleotide sequences as most reliable marker species differentiation genus.
