I think the striations are a result of the translucence of the cap. Smoothness of the cap/stem do seem to be traits not associated with Tricholomopsis.

rule out Tricholomopsis. Smooth, striate cap, shiny smooth stem, adnate to decurrent gill attachment, lack of large cheilocystidia (because I beleive this is the same as obs 96079..).

Nothing to rule out Tricholomopsis….

except maybe that these fruit bodies are so small. Sometimes it comes down to a few “maybes.”

Returned to where I had made this collection.

Found what I believe is the same type of mushroom, very close to where obs 95605 (this obs) was collected.

I did not keep the material. As usual, thanks for the suggestions.

take a look at spores and cheilocystidia..
To me, this doesn’t look like Tricholomopsis, more like Fayodia, Gamundia or maybe Hydropus.

No yellow…
