Inocybe griseolilacina, commonly known as the lilac leg fibrecap, is a mushroom in the family Inocybaceae. It was described scientifically by Danish mycologist Jakob Emanuel Lange in 1917.[1] It is inedible.[2] Its distinguishing characteristic is its pale yellow-gray and scaly cap and its fibrillose lilac stipe.

Its flesh, cap and gills often have lilac hues, as its name suggests. Its cap measures 1.5-3 cm across and is initially convex before flattening out with a small bump in the middle (umbo). The stipe is covered by a white cortina, when young and is lilac-coloured, occasionally having a pinkish hue at the top. It measures 1.4-6.7 x 0.1-0.6cm and is composed of thread-like fibers. The gills are adnexed to slightly sinuate and wider in the middle. They are 0.15-0.5 cm broad, and start of pale, darkening to gray and finally to umber. The odour and taste is sperm-like. [3]
The spores measure 8-11 x 4.5-5.5 μm and are almond shaped. The spore print is brown. The basidia have 4 spores each and are 26-33 x 8-10 μm. There are numerous pleurocystidia which measure 50-80 x 8-14 μm with 2 μm thick pale walls. They are variable in shape, ranging from spindle-shaped to utriform. The cheilocystidia are similar but less numerous. There are also numerous paracystidia which measure 7-10 x 5-7 μm, are club-shaped and have colorless, thin walls. Caulocystidia are absent. Clamp connections are present in all tissues.[3]
It is an ectomycorrhizal species, growing in association with a wide range of different tree species depending on the location, including conifer species in California, aspens in Montana and hardwood species in Europe.[3][4] In Europe it mostly occurs on calcareous soils in deciduous woodland and scrub areas, often with species of Fagus and Corylus.
