Inocybe erubescens, also known as
I. patouillardii, commonly known as the
deadly fibrecap,
brick-red tear mushroom or
red-staining inocybe, is a poisonous
basidiomycete fungus, one of many in the genus
Inocybe and one of the few known to have caused death. It is found growing in small groups on leaf litters in association with beech. All mushroom guidebooks as well as the
mushroomers advise that the entire genus should be avoided. The
fruit bodies (
i.e., the
mushrooms) appear in spring and summer; the bell-shaped
caps are generally pale pinkish in colour with red stains, with a reddish-pink
stipe and
gills.
