Inocybe griseolilacina, commonly known as the lilac leg fibrecap, is a mushroom in the family Inocybaceae.

[2] Its distinguishing characteristic is its pale yellow-gray and scaly cap and its fibrillose lilac stipe.

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.

[3][4] In Europe it mostly occurs on calcareous soils in deciduous woodland and scrub areas, often with species of Fagus and Corylus.
