摘　　要：描述了乳菇属的2个新种:皮壳乳菇Lactarius incrustatus和玫汁乳菇L. roseoligalus。该2种生于长白山和小兴安岭地区由蒙古栎、红松和桦构成的混交林下。皮壳乳菇属于乳菇亚属L. subg. Lactarius,特征为菌盖潮湿至近干、灰蓝或灰紫色、菌褶黄白色、盖表皮具深黄褐色皮壳附着物和孢子纹饰近斑马纹状。玫汁乳菇属于变红乳菇亚属L. subg. Plinthogalus,特征为乳汁白色快速变艳玫红色、孢子具高的排列为斑马纹状的纹饰和具褐色内含物的栅栏球囊型盖表皮。文中提供了该2种的外观和显微特征描述、与相近种的形态对比和真菌条形码ITS序列。Two new species Lactarius incrustatus and L. roseoligalus are described. These two species grow in mixed forests of Quercus mongolica,Pinus koraiensis and Betula in Changbai and Lesser Khingan Mountains. Lactarius incrustatus is a member of L. subg. Lactarius. The moist to dry grayish blue or grayish violet pileus,yellowish white lamellae,pileipellis with dark yellowish brown incrustations and spores with a more or less zebroid ornamentation distinguish this species. Lactarius roseoligalus belongs to L. subg. Plinthogalus and features latex rapidly changing to bright rose pink,subglobose spores ornamented with high ridges arranged in a zebroid pattern and pileipellis a trichoepithelium with brownish pigmentation. Macro-and micro-scopical descriptions,morphological comparisons with their look-alikes and fungal barcode ITS sequences of the two new species are provided.
