About Tricholoma sulphureum (Bull.) P.Kumm.
This mushroom, commonly known as the "Stinker" or "Sulfur Trich", is sulfur yellow in overall color. It has a convex cap that measures up to 8 cm (3 in) across; the cap is sometimes brownish near the center and has a vague umbo. Its gills are adnexed or notched, thick, and widely spaced. The stem can grow up to 10 cm long, and the mushroom produces a white spore print. The flesh is thin and has an unpleasant odor. The compound skatole causes this mushroom's distinctive smell, which is enough to separate it from other yellow fungi. Naturalist John Ramsbottom recorded that the mushroom has a complex smell that has been compared to jasmine, narcissus, hyacinth, Hemerocallis flava, lilac, tagetes, decayed hemp, or coal gas, and has also been described as nauseating or foetid. The taste of Tricholoma sulphureum is bitter. In distribution and habitat, Tricholoma sulphureum grows in deciduous woods, particularly beech woodland, and can fruit any time from spring to autumn. It occurs across Europe, and has been confirmed as far east as China. It is also found in North America, where it grows alongside conifers. In Turkey, this species is classified as critically endangered. For toxicity, this fungus is usually categorized as inedible and is suspected to be poisonous. Reported poisoning symptoms are mostly gastrointestinal, with some neurological effects also reported.
