Brown Rollrim?

Growing in felled coniferous woodland, some trees were still growing. I didn't take note of nearby trees. Fruitbodies were up to 12cm across. Taste was sour at first. I also wondered about Tapinella panuoides - Oyster Rollrim but I think the stem is too long and someone pointed out it is too large to be Oyster Rollrim that usually only grows to 8cm
