Who: Debbie Viess (amanitarita)

I had a mature fruit body in my tacklebox, and I did the microscopy last night.
This critter is feature rich!

9-12 × 4.5-5; 10 × 5, 11 × 4.5, 9 × 5, 10 × 5, 12 × 5, 12 × 5.

Cystidia on gill edge and face: mostly rounded like a hot air balloon, few shaped like bowling pin.

So looks like a Flammulaster, Gymnopilus is right out of there. Really looks like just about everything matches with F. muricatus, except the spores are too large. Should be 7-8 × 4-5 μm. Even the spore shape matches, just the size is off. Great photos of the cystidia, oh, good work here. I like it!

microscopy added.

about it looks vaguely Phaeomarasmioid, but I think Gymnopilus is a better guess.

Need to look at spores at least.

Probably old enough for spores. Slap a couple gills on a slide and get a photo of spores and some cystidia, that will get you further.

any ideas on this interesting mushroom?

I still have the fresh material, altho it seems a bit young for spores…
