Lactarius torminosulus
Lactarius torminosulus is a member of the large milk-cap genus Lactarius, in the order Russulales. A European species, it was officially described in 1996 from collections made in Norway. Fruit bodies (mushrooms) are small to medium-sized, yellowish orange in colour. Young specimens have a hairy cap margin; these hairs slough off in maturity—a field characteristic that can be used to help distinguish this species from the similar Lactarius torminosus. The fungus grows in a mycorrhizal association with dwarf birch species. Description The cap is initially convex before developing a central depression, sometimes becoming developing a papilla, and reaches diameters of . The cap surface of young specimens is hairy near the margin, which is usually fringed with hairs up to 5 mm long. The colour is initially pale cream to whitish, later becoming pale pinkish-buff to cream, with a more yellowish to yellowish-brown centre. The crowded gills have an adnate to decurrent attachment to the stipe. Whitish to pale pinkish-buff in colour, they are sometimes forked near the stipe attachment. The stipe measures long by in diameter, and is either cylindrical to slightly club-shaped to barrel-shaped. It has a smooth and dry surface with a salmon to pinkish-buff colour that
