中文摘要：

木生真菌在森林生态系统中是非常重要的功能有机体,对物质循环起着很关键的作用。近些年作者对中国热带地区的木生真菌进行了多样性调查及分类学研究。在对采集自中国海南省和云南省的木生真菌进行鉴定研究时,发现3个多孔菌：硬脆容氏孔菌Junghuhnia crustacea、热带针层孔菌Phellinus tropicalis和布兰切特多孔菌Polyporus blanchettianus,它们分别属于皱孔菌科、锈革孔菌科和多孔菌科,为中国木生真菌新记录种。根据采集的标本,对每种进行了详细的描述及显微结构绘图。

英文摘要：

Lignicolous fungi are very important functional organisms in forest ecosystem and play a key role in materials circulation. Diversity and taxonomic investigations on lignicolous fungi, especially from tropical zones in China, were carried out in recent years. During the investigations in Hainan and Yunnan provinces, three polypore species were identified as Junghuhnia crustacean, Phellinus tropicalis and Polyporus blanchettianus. They belong to the Meruliaceae, Hymenochataceae and Polyporaceae respectively, and are newly recorded from China. Descriptions and illustrations of these species are given based on the materials collected from China, and the relationships between their similar species are discussed.
