During an investigation of Diatrypaceae from southern China, 10 xylariales-like taxa have been collected. Morphological and multi-gene analyses confirmed that these taxa reside in Diatrypaceae and represent eight novel taxa and two new records belonging to six genera (viz ., Allocryptovalsa, Diatrype, Diatrypella, Paraeutypella, Peroneutypa , and Vasilyeva gen. nov.). Vasilyeva gen. nov. was proposed to accommodate Vasilyeva cinnamomi sp. nov. Among the other collections, seven new species were introduced ( viz ., Diatrype camelliae-japonicae sp. nov., Diatrype rubi sp. nov., Diatrypella guiyangensis sp. nov., Diatrypella fatsiae-japonicae sp. nov., Paraeutypella subguizhouensis sp. nov., Peroneutypa hainanensis sp. nov., and Peroneutypa qianensis sp. nov.), while two were reported as new records from China ( Allocryptovalsa rabenhorstii and Diatrype enteroxantha ). For Diatrypaceae , the traditional taxonomic approach based on morphology may not be applicable., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Li, Long, Lin, Wu, Wu, Hu, Shen, Zhang, Wijayawardene, Kang, Kumla and Kang.)

Several micro fungi were gathered from bamboo and palm in Guizhou Province, China. In morphology, these taxa resemble Neomassaria , Roussoella and Oxydothis . Multi-gene phylogenetic analyses based on combined ITS, LSU, SSU, rpb 2 and tef 1 loci confirmed that two are new geographical records for China, ( viz. Roussoellasiamensis , Neomassariafabacearum ), while two of them are new to science ( viz. Oxydothisfortunei sp. nov. and Roussoellabambusarum sp. nov.). The stromata of Roussoellabambusarum are similar to those of R.thailandica , but its ascospores are larger. In addition, multi-gene phylogenetic analyses show that Oxydothisfortunei is closely related to O.inaequalis , but the J- ascus subapical ring as well as the ascospores of O.inaequalis are smaller. Morphological descriptions and illustrations of all species are provided., (Hong Min Hu, Li Li Liu, Xu Zhang, Yan Lin, Xiang Chun Shen, Si Han Long, Ji Chuan Kang, Nalin N.

Three arecophila-like fungal samples were collected on dead culms of gramineous plants in China. Morphological studies of our new collections and the herbarium specimen of Arecophilagulubiicola (generic type) were conducted and the morphological affinity of our new collections with Arecophila was confirmed. Maximum likelihood and Bayesian analyses using combined ITS, LSU, rpb 2 and β-tubulin data from our collections revealed the phylogeny of Cainiaceae . The monospecific genus Alishanica (type species Al.miscanthi ), which had been accepted in Cainiaceae , is revisited and synonymised under Arecophila . Based on morphology and phylogeny, Arecophilaaustralis sp. nov. and A.clypeata sp. nov. are introduced as new species, while A.miscanthi is a new record for China. All the new collections are illustrated and described., (Qi Rui Li, Xu Zhang, Yan Lin, Milan C.

During an investigation of Xylariaceae from 2019 to 2020, isolates representing eight Nemania (Xylariacese) species were collected from Yunnan, Guizhou and Hainan Provinces in China. Morphological and multi-gene phylogenetic analyses, based on combined ITS, α-actin, rpb2 and β-tubulin sequences, confirmed that six of them are new to science, viz. Nemaniacamelliae , N.changningensis , N.cyclobalanopsina , N.feicuiensis , N.lishuicola and N.rubi ; one is a new record ( N.caries ) for China and one is a known species ( N.diffusa ). Morphological descriptions and illustrations of all species are detailed. In addition, the characteristics of Nemania are summarised and prevailing contradictions in generic concepts are discussed., (Yin Hui Pi, Si Han Long, You Peng Wu, Li Li Liu, Yan Lin, Qing De Long, Ji Chuan Kang, Ying Qian Kang, Chu Rui Chang, Xiang Chun Shen, Nalin N.
