Lactarius pseudomucidus, commonly known as the slimy milk cap,[1] is a North American species of fungus.
Description
[edit]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]
Similar species
[edit]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]
Distribution and habitat
[edit]It is native to northwestern North America, often found in coastal and conifer forests.[2]
