Found amongst leaf litter in an open beech wood.
Apologies for the poor photos.
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
In the book's they have a dark brown centre which in your photo they appear to have no dark centre,so maybe a different one,but does look similar.Have you any more picture's and any measurement's,or I could be wrong
Sorry, I have no more photos. I found it difficult to get the autofocus to work as you can see.
The cap was about 7-8 mm wide and the stipe about 3 cm long. Collins says M. rotula are white and mature darker. Jordan does say they are typically dark brown at the centre, but even if you look at the photo in Jordan's you can see varying shades of darkness, with the larger specimens being the darker,and the smaller specimens having only a pale tan centre, so that would seem to support Collins description. There was a definite collar.
The other alternative I had considered was M. epiphyllus, which would have similar dimensions and colouring, but the stipe of this appears to be more delicate than my specimen.
