Lactarius pseudomucidus, commonly known as the slimy milk cap, [1] is a mucilaginous species of fungus native to North America.
It has a charcoal brown cap, smooth and slimy, from 2–10 centimetres (3⁄4–4 in) across, initially flat convex, becoming shallowly depressed. The gills are decurrent, white with a gray or yellow tinge, staining brownish. [2] The stipe is 2.5–10 cm (1–4 in) tall and 5–12 millimetres (1⁄4–1⁄2 in) thick; [3] it is hollow and brittle. Both the cap and stipe are mucilaginous. [2] The flesh is gray and the latex is milky white, drying yellowish. [2] There is only a slight odor, and the taste slowly becomes acrid. Spores are white in mass, ellipsoid, amyloid, about 8 μm long, with a reticulate decoration on the surface. [4] [5] The spore print is cream. [3]
The species is inedible, [6] with the extremely viscid stalk and cap being deterrent. [1]
It resembles Lactarius argillaceifolius , which has a light orange-gray cap, [7] and eastern North America's L. mucidus. [2] Additionally, L. fumosus and Lactifluus gerardi bear similarities. [3] Other Lactarius species with slippery, grayish caps are either zonate and/or the gills stain purple. [3]
It is native to northwestern North America, often found in coastal and conifer forests. [2]
