NEw venue and mushrooms

Today I visited Doddington Hall in Lincoln as I'm going to be putting some pieces in a show there in August. It is a very well-run and beautiful old house with a farm shop, cafe etc. It hasn't been sold by the family since it was built in 1600. Even the shortcake that came with my latte was really nice. I returned to the studio to find mushrooms had started to grow out of a crack in a large sculpture that I've temporarily abandoned. Does anyone know if I can eat them?
