Puzzling! A Parasol?

Observation - Puzzling! A Parasol? - UK and Ireland. Description: At first I thought this was Pholiota but the stem is not shaggy. The double ring might point to Shaggy Parasol but the spore print is brown. Under but not near the trunk of an Ash tree. Difference in colour shade because I used flash on the 1st and 4th ph

At first I thought this was Pholiota but the stem is not shaggy. The double ring might point to Shaggy Parasol but the spore print is brown. Under but not near the trunk of an Ash tree. Difference in colour shade because I used flash on the 1st and 4th photos. I don't think the fungi I find read the books!
