Lactarius in Northern Thailand: 3. Lactarius subgenus Lactariopsis

Abstract

In this third paper in a series on Lactarius in Northern Thailand, Lactarius subgenus Lactariopsis is treated. In the area, this subgenus is represented by two species. Lactarius leoninus (previously described from Papua New Guinea) and Lactarius pilosus, which is proposed as a new species here. L. pilosus, close to the temperate species Lactarius vellereus. is characterized by a large, white to pale yellow, velvety pileus, pileipellis and stipitipellis structures with long, thick-walled terminal elements, and small spores.
