Hi, Quality could be OK, but to identify a mushroom you need at the very least a view of the lower side plus to these views. Is the lower side of the grayish-whitish ones formed of pores, like a fine sponge? Or is it in folds/gills, or maybe maze-like? They could be: Thick maze polypore; Thin maze polypore; Young specimens of green moss polypore; Or maaaaybe discolored turkey tail - I'm guessing not. The orange ones look like Picnoporus cinnabarinus to me. The bigger whitish one in the 2nd picture could be a Daedalea if the lower side matches. The ones with stems in the 3rd picture could be Polyporus squamosus if the lower side matches. Or decaying Armillaria mellea - honey mushroom, I think not though. Or are they your shiitake? I have never seen it growing, that might be it! The blackened ones behind them could be last year turkey tails. The brown ones in the last picture if they really have no stems (?) could be Ganoderma applanatum, but her lower side is very distinctive and there is a lot of flattish brown brackets similar to her. Generally speaking, you can't identify mushrooms from pictures. I am not bad with local ones in real life. Of course normally when you think you have the id it turns out that for a positive one you need to measure the spores or something...

No responsible person is likely to tell you whether or not a 'lawn' mushroom is edible or not by looking at a couple of images. And no one in their RIGHT mind would take that kind of advice to their saute pan. ;-) I mean, think about it! There are soooo many mushrooms with similar appearance that without the ability of examining them in person, an accurate identification cannot be guaranteed. Frankly, I might have been interested in identifying your mushoom if it were not for the fact that you are so interested in eating it! YIKES! That's why no one has answered your post, I am guessing. Sorry. You should consider them non edible. Try to find a mycologist or mushroom collector in your area.

Amanita vaginata, the grisette, or a close relative. Google it. The striate margin and unattached gills are characteristic. On the top of the cap are remnants of the universal veil and you should be able to find remnants of the corresponding volval bag at the base of the stem. Edible but not tasty. Don't eat Amanitas unless you really know what you're doing. Here is a link that might be useful: grisette

Bumping this up for Rory. Sorry no one answered. Possibly a Crepidotus sp. or Pleurotus ostreatus?
