your image is a deadringer for Cymatoderma elegans. I’m beginning to think Cymatoderma might be a fair guess for this ob. as well.

There are several names

for these many “fiber cups,” as I’ve oft heard them referred to, though I know of no good reference which groups the genera/species that share their common characteristics: lignicolous, infundibuliform, usually centrally stipitate, smooth-hymeniumed, solitary but gregarious habit. They are ubiquitous in the neotropics. The genera Cymatoderma, Podoscyphae, Stereopsis, Microporus and Cotylidia (though these are usually laterally stipitate and distinctly fan-shaped) all come to mind when I come across them, but it’s often an exercise in blindfolded darts to match the name to the mushroom; Cymatoderma and Cotylidia usually being two easily identifiable exceptions.

Every one of these is a wild guess, some based on names gleaned from those images in Petersen and Læssøe’s gallery pages (http://www.mycokey.com/Ecuador/PictureOfFungi.html – currently down) which bear a likeness to my own.

Coltricia are mycorrhizal; this appears lignicolous.

maybe Coltricia?
