Field Blewit (Lepista saeva)

The Field Blewit (Lepista saeva), also known as Lepista personata, is a popular late-season wild edible mushroom found across the UK. Unlike the woodland-dwelling Wood Blewit, the Field Blewit typically grows in open grassland, pastures, parkland and lawns. It is most easily recognised by its pale buff or beige cap combined with a distinctive lilac or purple stem. This contrast makes it one of the more noticeable autumn mushrooms in grassy habitats. Field Blewits often appear in fairy rings or scattered groups and are commonly found from late autumn into early winter, sometimes persisting after light frosts.

As a wild edible mushroom, the Field Blewit is well regarded for its firm texture and rich, savoury flavour. It is considered a good choice for foragers who can confidently identify it, but careful checking is essential due to potential confusion with certain Cortinarius species, some of which are poisonous. The absence of rusty brown spores and the presence of a purple-tinged stem are important identification features. When properly identified and thoroughly cooked, Field Blewits are excellent in soups, stews, risottos and creamy mushroom dishes. Because of their grassland habitat and distinctive colouring, they remain a rewarding find for UK foragers during the colder months.
