Lactarius crassus
Lactarius crassus, commonly known as the gasteroid milk cap, is a North American secotioid fungus species in the family Russulaceae. It was formerly known as part of the Arcangeliella genus, but recent research suggests that the contents of genus Arcangeliella should probably be transferred into the genus Lactarius. It was described from a collection made in Stanislaus National Forest, Northern California.
