I was searching the internet for hallucinogenic mushrooms that grow in the wild in The Netherlands, and are widely distributed (so I can pick some
).
I found one that grows from the spring until fall: the Pluteus salicinus, this mushroom have been reported to contain traces of psilocybin, psilocin and/or baeocystin. The mushroom is weakly to moderately active.
Description
The cap is 2 to 8 cm across, convex to plane, gray, smooth with tiny scales near the center, darker at the margin, often with blue or greenish stains. The gills are free and start out white, turning pink in age. The stem is 3 to 11 cm long and 2 to 5 mm thick, white with bluish or greenish stains, especially near the bottom. The spores are pink, smooth, 8 x 6 micrometres. It is always found growing on wood.
Habitat and distribution
Widely distributed across the British Isles, Northern Europe and the United States. This mushroom is often found in deciduous woodlands in riparian habitats, typically on alder (Alnus), willow (Salix), or on their woody debris.
Comments
Stijve and Kuyper (1985) reported 0.05-0.25 psilocybin, no psilocin, and from zero to 0.008 baeocystin. Christiansen et al. (1984) found 0.35 psilocybin and 0.011psilocin. See also Saupe (1981) and Stijve and Bonnard (1986). The Field Guide to Mushrooms of Southern Africa by G.C.A. Van der Westhuizen and Albert Eicker (1994) lists Pluteus salicinus as edible although their description lacks any mention of a bluing reaction. This species may have races that vary in their chemical content from region to region, much in the same way as Gymnopilus spectabilis. Caution is advised.

Does anybody have experience with eating this mushroom?
