Hi there, found some more at the site today, noted the host was likely Arctostaphylos, but the second likeiest host was NOT PIPO, but Quercus sp. for clarifications on this sp.

not likely nigrum

not likely nigrum as no specimens have eroded gills. I dont know all twenty plus Trichs up here but I will have to go with mutabile as I dig through a few other described purple-grey cappers.

T. nigrum

I have only seen it on the far north coast in CA. It doesn’t have a subviscid cap like these and gets dark scales on the stipe. The T. nigrum I have seen have a moist to dry cap, (not viscid at all)

T. mutabile has a cap similar to T. portentosum; slimy when wet and darker streaks.

cucumber to farinaceous smell in younger specimen was pronounced.
