at the moment, these pictures are making it tough; specimen in hand is worth a thousand pictures…

okay, so you are going with M. sumstenii…you must admit that the underside near the top of the petal is ALSO something that doesnt look right for the black stainer. So we are somewhere inbetween. Are you judging this somewhat by time of year?
Thats why I dont vote against what she notices.

She may be way over in Sweden but she knows our mushrooms better then most of us…
It’s just something(s) about this that doesn’t look right for Grifola

I was willing to venture that this was Meripilus, but not enough to go against Irene. I know shes all the way over in Sweeden, and Chaz is in LA…

It sure looks like it in those pics.And why I asked when they come out that far south.

that this is Grifola… Go back and collect some and bruise the pores, see if they turn black over time…

It looks like Grifola frondosa but Im not sure when they come out in your area.But it really doesent look thin enough to be Trametes versicolor.

Lay something next to it so we can judge the size when you check on the trees its near.

I will have to go back and look to see the tree it’s growing next to. It’s back there right now.

Is it possible you found this last fall?What trees were nearby??
