Oyster mushrooms

Feedback on this mushroom is appreciated.

@ Alex,it was difficult to peek at the gills because it is so tightly spaced. Sometimes I hesitate to touch mushrooms out of fear of inhaling the spores.
Looks like stretched leather.The biggest in the middle at least 10 cm for sure.
A Saprophyte for sure.
I will put all this info together and see what I can come up with.
Thankyou so much for your valuable feedback!

hi emma, that will get a long shot: 1 picture without any gill feature and dry caps. I will try: 1-basidiomyceta / 2- capped toadstoel / 3- maybe with gills /4 - cluster-growth / 5 center of the cap little darker - the rest light-brown, dark-cream / 6- on the second cap downward from the biggest.: a little area look a bit brown discolored. / 7- the cap rather snatch than krimp or decay by dry conditions / 8- saprophote, eating/growing on a log/wood. / 0- Was the biggest in the middle, maybe somewhat of 6-10 cm wide??
--searching on this condition in my (european mushroom) book i narrowed down: PHOLIOTA - Gummosa or alnicola
-- my feeling sys something like: genus Pluteus or collybia acervata (maybe you need to search some time , because my books are't up to date with the taxas and i have almost no references about usa mushroom accessible, except of the internet [ rogers mushrooms/mushroom expert/eol/wikip./mushroom observer/ ...etc] good luck emma but much further will i not come without the expierence of the actual spot. hope i will be more helpfull next time.

any idea on what type of fungus?

thanks bird lady!

Really cool!
