I have seen a lot of these over the last week. im 95% sure that its a field Blewit but would like confirmation.
The cap starts convex and then opens out growing up to 13cm wide. The cap is light brown, The gills and stalk are both lilac/light purple. Spore is light brown/orange although i would hesitate to say it was pink.
