Abstract

Seven field surveys were carried out in the Ailaoshan area of Yunnan Province, China, from 2016 to 2021, in which 2,814 specimens of wood-decaying fungal species were collected and identified based on morphology and phylogenetic analyses. One hundred and three wood-decaying species were identified, belonging to 64 genera, 29 families, and nine orders. Polyporales is the most abundant order in this area, accounting for 55.34% of all species, while Polyporaceae is the most abundant family, accounting for 18.45% of all species discovered in this area. The wood-decaying fungal checklist is provided according to the latest fungi classification system. Of these species, 11 are edible and therapeutic, four are forest pathogens, eight are threatened, and nine have just been reported from Ailaoshan Mountain. These species comprise 10.68%, 3.88%, 7.77%, and 8.74% of all species, respectively, while 71 species, or 68.93%, have unclear functional relationships. The sequences of the Internal Transcribed Spacer (ITS) gene region of the studied specimens were generated, and the phylogenetic analyses were performed with the maximum likelihood, maximum parsimony, and Bayesian inference methods. This study enriches the diversity of wood-decaying fungi in the Ailaoshan area. Also, it provides a theoretical basis for the future protection and utilization of wood-decaying fungal resources in this area.

通过形态和系统发育揭示中国云南哀牢山木材腐朽真菌的多样性

2016年至2021年，在中国云南省哀牢山地区开展了7次野外调查，共采集了2814份木材腐朽真菌标本，并根据形态学和系统发育分析对标本进行了鉴定。共鉴定出 103 种木材腐朽真菌，隶属于 64 属、29 科和 9 目。多孔菌目（Polyporales）是该地区数量最多的目，占所有物种的 55.34%；多孔菌科（Polyporaceae）是该地区数量最多的科，占在该地区发现的所有物种的 18.45%。木材腐朽真菌清单是根据最新的真菌分类系统提供的。在这些菌种中，有 11 种可食用和治疗，4 种是森林病原体，8 种是濒危菌，9 种是刚刚在爱老山发现的。这些物种分别占所有物种的 10.68%、3.88%、7.77% 和 8.74%，而功能关系不明确的物种有 71 种，占 68.93%。研究生成了所研究标本的内部转录间隔区（ITS）基因序列，并采用最大似然法、最大解析法和贝叶斯推断法进行了系统发生分析。该研究丰富了爱老山地区木材腐朽真菌的多样性。同时，也为今后该地区木材腐朽真菌资源的保护和利用提供了理论依据。

期刊介绍： Phytotaxa is a peer-reviewed, international journal for rapid publication of high quality papers on any aspect of systematic and taxonomic botany, with a preference for large taxonomic works such as monographs, floras, revisions and evolutionary studies and descriptions of new taxa. Phytotaxa covers all groups covered by the International Code of Nomenclature foralgae, fungi, and plants ICNafp (fungi, lichens, algae, diatoms, mosses, liverworts, hornworts, and vascular plants), both living and fossil. Phytotaxa was founded in 2009 as botanical sister journal to Zootaxa. It has a large editorial board, who are running this journal on a voluntary basis, and it is published by Magnolia Press (Auckland , New Zealand). It is also indexed by SCIE, JCR and Biosis. All types of taxonomic, floristic and phytogeographic papers are considered, including theoretical papers and methodology, systematics and phylogeny, monographs, revisions and reviews, catalogues, biographies and bibliographies, history of botanical explorations, identification guides, floras, analyses of characters, phylogenetic studies and phytogeography, descriptions of taxa, typification and nomenclatural papers. Monographs and other long manuscripts (of 60 printed pages or more) can be published as books, which will receive an ISBN number as well as being part of the Phytotaxa series.
