This paper reports on Lactarius subgenus Plinthogali from Northern Thailand and is the second in a series resulting from a complete revision of the genus for the area. Four taxa are described as new for science: L. crassiusculus, L. lavandulus, L. friabilis and L. subplinthogalus var. chiangmaiensis. Lactarius oomsisiensis and L. montoyae are reported for the first time outside Papua New Guinea and India respectively. Phylogenetic analysis of the ITS sequence was used to test conspecificity and support species delimitations. Lactarius aff. gerardii is reported in Thailand; however, our results demonstrate L. gerardii is a species complex forming a separate clade from the other members of L. subg. Plinthogali.
