Cystodermella granulosa exhibits (at least to some extent) each of the traits you mention http://www.mycoquebec.org/... .

of Cystoderma s.l. is based mostly on the presence of a granular/cyst-having pileus surface/dermis, coming in a range of fall colors, having pale gills, and an ornamented, sheathing annulus and lower stipe. This has all of the above, doesn’t it?

Somewhat ambiguous appearance…

except for the grainy sheath/coating seen on the lower half of the stipe, which I believe eliminates Laccaria from consideration. My understanding is that Cystoderma/Cystodermella are distinguished as per amyloidity/inamyloidity of spores.
