If you mean dear mushrooms to be Pluteus cervinus, then I can say that I eat them. (I cannot confirm that your picture is of P. cervinus, however). Make sure it has a pinkish spore print. This along with the fact it grows on wood (i.e. it is not an Entoloma) and that it has no volva (i.e. it is not a Volvariella) makes for 3 very good identifying characteristics. They are a good filler mushroom, meaning they don't taste great but if you need a standard tasting mushroom for something, this is good. I find they come out a little slimy after cooking, as well. Lastly, most people think they get their name 'deer mushroom' because deer eat them. This is incorrect; they get their name because the cap color.
Thanks so much, I'll check for a pink spore print, ans everything else is a confirmation. I'm worknig on a catalog of local mushrooms. I should have some Russulas (Emetric) coming up
