Inocybe fastigiata (Schaeff.) Quél.

Inocybe rimosa (formerly known as Inocybe fastigiata), commonly known as straw-colored fiber head, is a poisonous mushroom native to Europe. Its toxic ingredient is muscarine, discovered during the 1930s.[1] Serious poisoning can result from consuming any quantity of the mushroom.[2]

German naturalist Jacob Christian Schäffer described this species in 1774. Lucien Quélet transferred it to the genus Inocybe in 1872.[3]

The tan (or rarely whitish) cap is cone-shaped then expands, generally retaining an umbo and a darker center. Its surface is fibrous. The gills are light grayish and brown with age. The stalk is whitish, semi-fibrillose, and slightly clavate. The odour tends to be spermatic.[4]

In Israel, the species grows under Palestine oak (Quercus calliprinos) and pines, with mushrooms still appearing in periods of little or no rain as they are mycorrhizal.[5]

In Israel, it is confused with edible mushrooms of the genus Tricholoma, particularly Tricholoma terreum, and Suillus granulatus, all of which grow in similar habitats.[5] I. sororia is another similar species.[4]
