I saw the same thing

with Mycena and Prunulus; someone had put them in the family Morchellaceae, perhaps as a joke. If it hasn’t already been done I’ll fix Pleurotus too.

great suggestion…

The listed family is the Morchellaceae (!)
Unless the phylogenies have gotten REALLY weird without my noticing, this is wrong.

Most likely Pleurotus

Dry a tiny piece of gill between two sheets of paper and take it back for further study. This works well when one is far away and lacks a dehydrator.


point taken.

I seized on that whole woodrotter thing, then justified the rest of the ID. It could be Pleurotus. Looking harder at one of the clustered in situ shots, the edge of the youngest cap actually seems to show the pinkish spore color typical for a Pleurotus. So sure, why not Pleurotus?

Why do you call Pleurotus unlikely? Do you have a better idea?

and M. platyphylla doesn’t occur in NA. But Megacollybia have thick widely spaced gills that will appear or even be free of the stipe…

that can have entire or serrate gill edges, a cap with radial fibrils, a center stipe (pretty substantial stipe for a pleurotus, eh guys?) and it can so grow on wood.

gill edges

Are the gill edges serrate? Maybe a Lentinus?

There went my I.D. … On the other hand, I HAVE seen oysters
almost this large, but they didn’t have a central stem.
Could it be similar to Hypsizygus ulmarius?

These were growing on a tree.

Growth pattern?

Were these growing from the ground, or from a tree?

Pleurotus seems likely

No idea what the species would be. Certainly are big! Perhaps they should be called Giant Clam Mushrooms.
