摘　要：在調(diào)查研究蜜環(huán)菌生物種的過程中，先后在東北、華北、華中和西南地區(qū)，發(fā)現(xiàn)了四個(gè)新的中國蜜環(huán)菌生物種，CBSF、CBSG、CBSH和CBSI。研究表明，CBSG屬于典型的同宗配合種，其余三個(gè)為異宗配合。CBSH與CBSC之間存在部分互交可育，比例高達(dá)17.8%，在同一個(gè)國家的兩個(gè)種之間出現(xiàn)如此高的互交可育比例還是首次報(bào)道。上述三個(gè)生物種同歐美的已知蜜環(huán)菌種均互交不育，為亞洲特有種。CBSI為無菌環(huán)的假蜜環(huán)菌A.tabescens(Scop.)Emel，它與歐洲的假蜜環(huán)菌互交可育，屬于同種。但同中國其它各生物種互交不育。同時(shí)討論了蜜環(huán)菌生物種的群體觀點(diǎn)。

Abstract：Four new biological species of Armillaria in China were determined from forty basidiocarps which collected from northern and southwestern China by total 4560 pair combinations of singles spore isolates. Twelve basidiocarps were deduced sexuality: homothallism from 3 basidiocarps and heterothallism from other 9 ones. These four species was named Chinese Biological Species(CBS) F, G, H, I, repectively, and intersterile with European and North American species of Armillaria except CBS I which was compatible with European A.tabescens (Scop.) Emel completely and should be considered conspecific. CBS G is homothallic species and distributed in southern China. CBS F is heterothallic species and distributed in northeastern China mainly. CBS H are heterothallic species and partial compatible with CBS C. The seasonal and geographical information of these CBS are discussed as well.

Keywords：Armillaria, Chinese biological species of Armillaria, A.tabescens, Homothallism, Heterothallism
