saevum Tricholoma saevum Rhodopaxillus personatus Rhodopaxillus saevus Agaricus anserinus Agaricus personatus β saevus Collybia personata (also recognised as Lepista personata, Lepista saeva, Clitocybe saeva and Tricholoma personatum, and commonly known as the field blewit and blue-leg) is a species of edible fungus commonly found growing in grassy areas across Europe and is morphologically related to the wood blewit Collybia nuda (formerly Lepista nuda).

[2] In Latin, the specific epithet sævus is an adjective meaning either fierce, outrageous, angry or strong.

The cap cuticle is colored cream to light brown with a smooth texture to the touch, and is often seen glistening when fresh.

The underside of the cap bears crowded pinkish, cream to light brown gills, which are free or emarginate in relation to the stem.

The stem is covered by a striking lavender or lilac-coloured fibrous skin which fades in older individuals, and has a thick, firm flesh concolorous with that of the cap.

[8] Blewits can be eaten as a cream sauce or sautéed in butter; they can also be cooked like tripe or as an omelette filling.
