The micro illustrations on that page are excellent!

As for macro features: I did note the lack of odor, but didn’t hang around to note color change as it dried out. (Heh, it might’ve been several days before that happened! :) I didn’t think to look for cross-veins; I’ll keep that in mind next time.

Some things that are useful are:

Macro:
Gill intervenosity/transvenosity
color changes (ie. hygrophanous?)
odor

Micro:
Spore length and degree of angularity
ESPECIALLY USEFUL: pileipellis type and distribution of pigment (intracellular and diffuse, encrusted, globular etc)
some possible types: chains of roundish cells, upright cylinders, horizontal cylinders, presence of gelatinous layer, transition between horizontal and upright cells, for an illustration, go here:

Presence of clamps

I couldn’t collect or get spores, so it’s kind of moot in this case, but good to know for the future…

which belongs to Entoloma, not section Leptonia.

The distinction between sections isn’t as clear as it used to be before the DNA era..

no doubt, but whether it belongs in Entoloma or Leptonia I know not.
