摘　　要：从分子角度对红汁乳菇(Lactarius hatsudake)、半血红乳菇(Lactarius semisangui fluus)及橙色乳菇(Lactarius akahatsu)的分类地位进行了阐述。利用真菌通用引物对湖南衡阳的红汁乳菇rDNA的转录间隔区(ITS)进行扩增、测序。所得序列与GenBank中的半血红乳菇及橙色乳菇的ITS序列比较,最后得出Lactarius semisanguifluus和Lactarius hatsudake是同物异名,而Lactarius semisanguifluus和Lactarius akahatsu则不是同种的结论;试验中还发现GenBank中的AF096988 Lactarius semisanguifluus是错误的命名种,应该是乳菇属中的松乳菇。The rDNA ITS of Lactarius hatsudake from Hengyang, Hunan Province was amplified using common primers of fungi and sequenced,the sequnce of which was compared with those of Lactarius semisanguifluus and Lactarius akahatsu from GenBank. The result showed that Lac- tarius sernisangui fluus is the same species to Lactarius hatsudake , and Lactarius sernisangui- fluus is different from Lactarius akahatsu. Besides, the AF096988 Lactarius semisanguifluus in GenBank was wrongly named and should be Lactarius deliciosus.
