Fungal diversity is rapidly expanding, with numerous species being discovered worldwide. While plant debris is a habitat favoring the survival and multiplication of various microbial species. In this study, several kirschsteiniothelia-like isolates were collected from dead branches of unidentified perennial dicotyledonous plants. Based on morphological examination and phylogenetic analyses of combined ITS, LSU, and SSU sequences data using maximum-likelihood and Bayesian inference, three new species of Kirschsteiniothelia, namely K. ganzhouensis, K. jiangxiensis, and K. jiulianshanensis, were introduced, and one known species, K. inthanonensis, was recorded for the first time from China. To improve our comprehensive knowledge of the species diversity of Kirschsteiniothelia, all accepted Kirschsteiniothelia species with morphological characteristics, sequence data, asexual morphs, habitat, host, and locality are listed.

Several genetic transcription factors have been discovered to influence DNA replication, yet the precise mechanism has not been found. Increasing chromatin accessibility might be a crucial mechanism of transcription factors during multiple nuclear processes. This has been suggested by observing that the acidic transcriptional activation domain of the breast cancer BRCA1 can alter local chromatin structure while stimulating DNA replication.

Saprobic hyphomycetes with high density and species diversity were observed on plant debris. During our mycological surveys in southern China, numerous strains were isolated from dead branches of unidentified plants in the forest of Jiangxi and Fujian provinces, China. Phylogenetic analyses of ITS, LSU, RPB2 , and TEF1 sequence data using maximum-likelihood (ML) and Bayesian inference (BI) methods revealed the systematic placement of several Sporidesmium -like species within Distoseptispora . Based on morphological characteristics and molecular evidence, four new species of Distoseptispora , namely D.fujianensis , D.ganzhouensis , D.nanpingensis and D.subtropica , are introduced, and two known species, D.clematidis and D.yunjushanensis , are reported. This study enhances our knowledge of the species diversity of Distoseptispora in southern China., Competing Interests: The authors have declared that no competing interests exist., (Ming-Gen Liao, Xing-Xing Luo, Ya-Fen Hu, Rafael F.
