this drying specimen actually is…

minutely squamulose at the cap margin.
when the fruit bodies were still wet, the cap was smooth.

certainly not “striate to translucently striate” like should be shown for riparius, and it was NEVER “subviscid to viscid.”

we will be able to confirm one or the other or neither once the DNA funding comes in.

could match any number of little orange-brown Lactarius… “surface finely rimulose or over the disc finally minutely squamulose from checking of the cuticle” or “squamulose when young” Does not match your specimen.

amyloid spores w/a partial reticulum…it’s a match!
