Morphological and phylogenetic analyses reveal two new species of Niesslia (Niessliaceae, Hypocreales) from China

This dataset contains the digitized treatments in Plazi based on the original journal article Tian, Xin, Zhang, Ming-Yi, Hou, Jian-Gan, Wu, Yun-Jie, Zhang, Zhi-Yuan (2026): Morphological and phylogenetic analyses reveal two new species of Niesslia (Niessliaceae, Hypocreales) from China. MycoKeys 127: 73-87, DOI: 10.3897/mycokeys.127.175675AbstractThe genus Niesslia is common on decaying plant and fungal substrates, as well as in soil. During a survey of culturable mycobiota in urban soils, six Niesslia isolates were obtained in Shanxi Province, China. Based on combined multigene phylogenetic analyses (ITS, LSU, TEF 1, TUB and ACT) and morphological characteristics, two novel species, Niesslia curvispora and N. shanxiensis, are proposed. Detailed morphological descriptions, illustrations and phylogenetic analyses of the new taxa are presented.
