This site contains no information about the edibility or toxicity of mushrooms.
Paxillus involutus, also known as Poison Pax, is a medium to large, widely distributed, variable species with a strongly inrolled, yellow- to red-brown cap and crowded, decurrent gills extended down on the firm stem. The mushroom grows solitary or in trooping groups on soil in leaf woods.

Cap initially convex then more funnel-shaped with a depressed centre and rolled rim, may be reddish-, yellowish- or olive-brown in colour. The surface is initially downy and later smooth, becoming sticky when wet. Gills brownish yellow, narrow, decurrent (running down the stem), and can be peeled easily from the flesh. They further down toward the stem become more irregular and anastomose. If the gills are bruised they very rapidly turn rusty brown. Stem is similarly coloured as the cap, however bruising darker brown. It is smooth, equal or tapering downwards. The stem has no ring. Spore print purplish brown to yellow-brown..

Microscopic Features: The spores are ellipsoidal and smooth, measuring 7.5-9 x 5-6┬Ám.

Many mushrooms are poisonous and some are lethally poisonous. It can be very difficult to distinguish between an edible and a poisonous mushroom. Because of that, we strongly advise against consuming wild mushrooms, and this site does not contain any information about the edibility or toxicity of mushrooms.
