摘要: 大型真菌在生态功能和社会经济效益上具有重大价值。为系统分析中国西南喀斯特地区大型真菌的区系组成与物种多样性特征,探究特殊地貌类型对大型真菌生长分布的影响,本研究通过样线法和随机踏查法,历时7年采自贵州、广西、云南大型真菌样本12,451份,结合形态学与ITS序列证据进行鉴定,并通过查阅相关文献资料,对该地区大型真菌的区系特征和资源价值进行分析。结果显示,西南喀斯特地区大型真菌共1,505种(2门10纲27目118科418属),其中包括已发表新种19个、中国新记录种1个、贵州省新记录种1个。优势科共41个(34.75%),包括红菇科、多孔菌科、牛肝菌科等;优势属73个(17.46%),包括红菇属(Russula)、鹅膏属(Amanita)和乳菇属(Lactarius)等。对大型真菌资源价值的评价结果显示,食用菌、药用菌和毒蘑菇分别为263种、176种和237种,表明该区大型真菌资源十分丰富。科级区系地理成分以世界广布成分为主,属级区系地理成分则表现出一定程度的多样性。研究结果可为西南喀斯特地区大型真菌多样性保护和资源合理利用提供可靠依据。

Abstract

Aims: Macrofungi hold significant ecological and socioeconomic value. To analyze the floristic composition and species diversity of macrofungi in the karst areas of southwestern China and clarify the influence of distinctive geomorphological features on their distribution, a comprehensive survey was conducted. The results are expected to provide a scientific basis for biodiversity conservation and sustainable utilization of macrofungal resources in the areas. 

Methods: Over a seven-year period, 12,451 macrofungal specimens were collected from Guizhou Province, Guangxi Zhuang Autonomous Region, and Yunnan Province using line transect and random survey methods. Species identification integrated morphological characterization and molecular phylogenetic analysis using ITS sequences. Taxonomic data were cross-referenced with literature to analyze floristic components and resource values. 

Results: A total of 1,505 macrofungal species (2 phyla, 10 classes, 27 orders, 118 families, 418 genera) were identified in the karst areas of southwestern China. Among these, 19 new species, 1 newly recorded species in China, and 1 new record for Guizhou have been published. Dominant families constituted 34.75% of total families (41/118), with Russulaceae, Polyporaceae, and Boletaceae exhibiting the highest species richness. At generic level, 17.46% of genera (73/418) demonstrated dominance, particularly Russula, Amanita, and Lactarius

Conclusions: The evaluation of macrofungal resource values identified 263 edible species, 176 medicinal species, and 237 toxic species, indicating considerable fungal diversity in this region. Floristic analysis revealed cosmopolitan distributions predominate at the family level (54.24%), while higher biogeographic diversity was observed at the genus level.
