Now that I think about it, it could possibly be a conifer of some sort. I assumed maple because the forest is comprised of nearly all maples, what’s left are choked out hemlocks and a few firs. This could of been one of those. I’ve found Gymnopilus ventricosus in the same forest so my assumption of maple could be wrong.

According to “Tricholomopsis in the Western Hemisphere”…

T. sulferoides has a fimbriate gill edge, which make me wonder about all of the observations with even gill edges. Smith describes a Var. megaspora in which the gill edge is “floccose/fimbriate” whatever that means, and the cells agglutinate in age to form olivaceous pigments. that seems a little more consistent with the modern concept.

I don’t think T. bella or T. thompsoniana in which the lamellae stain strongly. There are several species in both Singer and Smith’s concepts that posses fimbriate gill edges, but most belong in the group with T. rutilans or the group that would’ve housed M. rodmanii.

Idk, T. sulferoides actually sounds pretty good to me.

Brad, are you sure this wasn’t Hemlock?

to the papillae cap at times but no to the crenulate lamellae. Also this seems a bit fuzzy at the cap margin.

Does T. sulphureoides have crenulate lamellae? or such a prominent papillae?
