中国鸡油菌科分类及系统发育研究

鸡油菌科是大型担子菌中重要类群，有著名野生食用菌，具有重要经济价值和生态功能。该类群分布广，种类多，形态独特，表型可塑性强，具相对独立的演化路线，是研究大型担子菌系统发育与进化的关键类群。该科已有研究主要集中在欧洲、北美洲、非洲和东南亚地区；我国研究有限，且不少标本被误定为欧美种类，物种多样性、分布情况、亲缘关系等尚不够明确，亟待研究。本项目对中国鸡油菌进行分类与系统发育研究，在新的资源调查及已知种复核的基础上，结合形态特征和分子数据进行分类鉴定，分析形态种与系统发育种关系，明确物种划分依据，修订不合理系统与类群，发现新分类群，阐明中国鸡油菌科物种多样性与分布情况；综合形态特征、系统发育框架、地理生态信息等，分析种间亲缘关系，探讨该类群物种起源与演化。本项目将极大丰富我国鸡油菌物种多样性，对正确认识鸡油菌进化史、理解大型真菌起源与演化有重要意义，并为鸡油菌资源保护与可持续利用提供科学依据。

Cantharellaceae J. Schröt., a kind of important macro-fungi in Basidiomycota, which contains some famous wild edible mushrooms, has important economic value and ecological function. This group has wide distribution, species diversity, unique morphology, strongly plastic phenotype, and relatively independent evolution route. Cantharellaceae is a key group for studying the phylogeny and evolution of macro-fungi. Previous studies on Cantharellaceae are mainly concentrated in Europe, North America, tropical Africa and Southeast Asia. Researches on Cantharellaceae is poor and limited in China, many Chinese species are misidentified as European or North American species, so the species diversity, distribution and phylogenetic relationships are not yet clear, and related researches are urgently needed. In this project, a phylogenetic classification of the Cantharellaceae will be carried out. On the basis of new resource investigation and collection and review of known species, combining morphological characteristics and molecular data, the relationships between morphological species and phylogenetic species will be analyzed. The purpose is to clarify the basis for species classification, revise unreasonable taxa, discover new species or new records, and clarify the species diversity and distribution of Cantharellaceae in China. Comprehensive morphological characteristics, phylogenetic framework, and geographic ecological information, etc. to analyze the species relationship and discuss the origin and evolution of Cantharellaceae. This study will greatly enrich the species diversity of Cantharellaceae in China, which is of great significance for correctly understanding the evolutionary history of Cantharellaceae, understanding the origin and evolution of macro-fungi, and providing a scientific basis for the protection and sustainable use of Cantharellaceae resources.
