Lactarius kauffmanii is a species of mushroom in the family Russulaceae.[1] It is found in Western North America.[2]

Taxonomy

The species was described as Lactarius kauffmanii in 1979 by the American mycologists Lexemuel Ray Hesler and Alexander H. Smith.[3]

Etymology

The species is named for Calvin Henry Kauffman who collected specimens on his expedition to Lake Cushman, Washington in 1915.[3]

Description

The cap of Lactarius kauffmanii is tan to grayish brown in color and about 4-15 centimeters in diameter. It becomes browner in color as it gets older. It is convex to flat and sometimes depressed.[4] The gills are pale to pinkish[5] and adnate to subdecurrent. The stipe is white or cream to tan in color and becomes ochre or orange as the mushroom gets older.[4] The spore print is white to creamy.[6] When cut, this mushroom produces large amounts milky white latex. This latex leaves orangish tan stains.[4] This mushroom has an acrid taste.[7]

Habitat and ecology

Lactarius kauffmanii is mycorrhizal. It grows under hemlock and fir. It may also grow with other types of conifers. It is found in forests.[2]
