Shows pink spore deposits on the pileus.

though still having a hard time reconciling such free gills with Mycena. Thank you, Alfredo.

The very glutinous cap and stipe surfaces, and the completely transparent stipe makes me think more of Mycena s. lato than of Pluteus

It is true that some species of sect. Celluloderma, specially the tropical ones, can can have somewhat similar caps to this observation (without being so viscid), and some can also have shiny, a bit transparent stipes, but overall, I think this goes into Mycena s. lato.

A quick look under the microscope at the hymenium and pileipellis will point you in the right direction

Yes, thanks for the link

The character combo is still making me uneasy. The only two there with (sub)distant gills are missing the flimsy cap flesh, the crenate cap margin, and (on one) the mycenoid stipe of this obs. I don’t see any hint on this obs of the typical longitudinal texture of Pluteus stipes.

the pluetus you’re familiar with is not similar to these, but this fits my concept pretty well. Alfredo is the man to ask. check out the sect. Celluloderma portion of the following page:


to see examples of small pilei, thin, shiny, mycenoid/entolomatoid stipes, etc.

being neither in the Americas nor Europe adds a layer of questionability to everything…

not saying it’s not Pluteus (voted Could Be), just seems like a stretch to call the obs that…

if you can link any similar mushrooms to these that look more like the Pluteus we’re familiar with…

why not Pluteus?
