Lookalikes to rule out
Violet webcaps
toxicCortinarius have a cobweb-like veil when young and leave a rusty-brown spore print.
Lilac fibrecap
toxicInocybe species are smaller, fibrous-capped, and drop brown spores.
Amethyst Deceiver
harmlessAmethyst deceiver is smaller and slender, with thick, widely spaced gills.
Identification
Young caps are violet to lilac and smooth, fading to tan with age. The gills are crowded and lilac, and the thick stem is often slightly bulbous and violet-tinged. The smell is fruity and sweet, like frozen orange juice. The decisive check is the spore print: pinkish buff, never rusty brown.
Uses and ecology
Blewits recycle leaf litter and compost, often fruiting in rings. They appear late in the season after frosts. They should always be cooked, and people trying them for the first time should eat a small amount.
Memorable fact
Blewits often fruit in the same compost heap year after year, sometimes after the first frost has ended most other mushroom seasons.
