本文报道乳菇属(Lactarius s.F.Gray)的30个种,其中黑茸乳菇(Lactarius atrovelutinus Ying):毛脚乳菇(Lactarius hirtipes Ying)为新种;另外28种乳菇是中国的新记录种。对乳菇属的特征、界限及其实用价值亦予以简介。
Thirty species of Lactarius are reported in present paper. Lactarius atrovelutinus Ying and Lactarius hirtipes are described as new to science; twenty eight species of Lactarius are new to China.Lactarius atrovelutinus Ying is characterized by small, blackish brown, minutely velvety pileus and stipes, latex and context white then changing pinkish; white to pinkish cinnamon lamellae and globose reticulate spores. It is readily distinguished from Lactarius subgerrardii Hesier et Smith by the changing context and latex, and the globose spores with complete reticulum. The dry, velvety and dark colored pileus, cuticle with Virescens structure and the latex changing cinnamon, indicate that this species belongs in Section Plinthogal, Subsection Fuliginosi.Lactarius hirtipes Ying may be recognized by the dry, umbellicate or depressed, azonate cinnamon rufous pileus, somewhat cinnamon tinted whitish iameliae, white latex, strigose stipes, fragrant of camphor and structure of pileus cuticle. It is best placed in Section Russulares. It seems to be close to Lactarius atlanticus var. Strigipes Bon, except the different color and odor, especially the microscopic features, i.e. cystidia and larger spore present in the new species. It is somewhat related with Lactarius camphoratus (Bull.:Fr.) Fr., but differs from the latter in the strigose stipe and the cinnamon rufous color, the larger spores and pleurocystidia. In short, the spore size, the pleurocystisia and color of basidioma prevent assignment to either species.Characters, limits, as well as practical importance of this genus are also described briefly.All the specimens cited above are deposited in the Herbarium Mycologicum Instituti Microbiological, Academia Sinica (HMAS).
