This has all the characteristics of a Burnt Knight (Tricholoma ustale) in my Collins guide. It was found among a small stand of birch trees, quite close to another very similar mushroom posted on this site which I originally thought was a different one - Tricholoma ustaloides - but I think that other one might be a mistaken ID and that it is, in fact, an older Tricholoma ustale. The gills are certainly very similar.
