Lactarius pseudomucidus, commonly known as the slimy milk cap,[1] is a fungus native to the northwestern part of North America, often found in coastal and conifer forests.[2] It has a charcoal brown cap, smooth and slimy, from 2–10 cm across, initially flat convex, becoming shallowly depressed. The gills are decurrent, white with a gray or yellow tinge, staining brownish.[2] The stipe is 40–100 mm tall, hollow, 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.[3][4] The species is inedible.[5] It resembles Lactarius argillaceifolius, which has a light orange-gray cap,[6] and eastern North America's Lactarius mucidus.[2] It's edibility is unknown, but the extremely viscid stalk and cap are a deterrent.[1]
