Deadly Fibrecap
Inocybe erubescens – Poisonous

Parks, more rarely deciduous forests. May–June, later rarely.
Fruiting bodies medium-sized. Cap 3–9 cm, conical, bell-shaped, fibrous, whitish when young, later yellowish, yellowish-orange, red-spotted. Gills white, later greyish-brown. Stem 3-8 (10)x0.5-1.5 cm, thickening towards the base, white, without a ring. Flesh white, soft, with an unpleasant smell and taste. Characteristic features: cap, gills, stem and flesh turn red when pressed or broken. Grows in spring, favouring calcareous soil. Not rare. A deadly poisonous fungus, containing 20 times more muscarine than the fly agaric. Similar to the field and edible (horse) mushrooms, but these do not turn red and their gills are chocolate-coloured and the stem has a ring; also similar to St George's mushroom, but that does not turn red when pressed or cut.
