Abstract: Three new species of Xylaria on fallen leaves in Hainan Province of China are described and illustrated, based on morphological and molecular evidence. Xylaria hedyosmicola is found on fallen leaves of Hedyosmum orientale and featured by thread-like stromata with a long sterile filiform apex. Phylogenetically, X. hedyosmicola is closely related to an undescribed Xylaria sp. from Hawaii Island, USA and morphologically similar to X. vagans. Xylaria lindericola is found on fallen leaves of Lindera robusta and characterised by its subglobose stromata and a long filiform stipe. It is phylogenetically closely related to X. sicula f. major. Xylaria polysporicola is found on fallen leaves of Polyspora hainanensis, it is distinguished by upright or prostrate stromata and ascospores sometimes with a slimy sheath or non-cellular appendages. Xylaria polysporicola is phylogenetically closely related to X. amphithele and X. ficicola. An identification key to the ten species on fallen leaves in China is given.

A taxonomic study of Nemania from China, with six new species https://mycokeys.pensoft.net/article/69906/ MycoKeys 83: 39-67

DOI: 10.3897/mycokeys.83.69906

Authors: 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. Wijayawardene, Xu Zhang, Qi Rui Li

Abstract: 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. Nemania camelliae, 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.
