Abstract: Among of the vast numbers of fungi, key taxa are of great importance for scientific research, economic development and ecosystem management. It is urgent and necessary to select and determinate key taxa from the species recorded from China. Based on many field investigations and analysis of literature about larger members in higher fungi from China, with reference to the selecting and determining principles and methods used for animals and plants, three types of key taxa were proposed: endangered taxa, impor-tant taxa for scientific research and important groups for economy.

Key words: Larger members in higher fungi

摘要： 由于生物多样性的关键类群在科学研究、社会经济及生态系统中所处的重要地位，有必要对其进行筛选和确定。在多年的野外考察和有关文献资料分析的基础上，参照植物和动物关键类群的划分原理及方法，结合高等真菌的特点将大型高等真菌划分为& 种类型：濒危类群、重大科学价值类群和重要经济类群。其中，濒危类群指在近年的考察和报告中发现的数量急剧减少或由于过度的采集资源明显受到威胁的种类，......
