Deer Mushroom, Pluteus cervinus. The foraging websites cannot generate enthusiasm about its culinary qualities, talking of a 'radishy' flavour, which goes away if fried and leaves the 'earthy' flavour dominant. Which is why these specimens survived: Dimitri the professional forager (my main mushroom competitor) would have sold them to local restaurateurs, if he had managed to create a market.
Stewed, with caramelised onions and fine-chopped carrot, celery and daikon.
