if possible, check the cheilocystidia again. they appear to be at least one diagnostic character. measuring both those and spores may be essential to identifying this with any certainty.

I don’t know what you’re talking about, but the gills look very similar in each photo.

Yes, but the specie from Ecuador (Photo: http://www.mycokey.com/... ) have triangular gills, and the panamanian specie have ovalated gills, not the same fungi.

this is simply the only species I know of which has been reduced to gills and only gills. I was introduced to it at MycoKey Ecuador. Descriptions like Smith’s from North American Species of Crepidotus don’t seem to describe the same mushroom:

Pileus 1-6 mm broad, sessile, resupinate to reflexed, semiorbicular, reniform, to conchate, at first white, then brown, margin fuscous, floccose, puberulent, villose at the point of attachment. Context thin.

Lamellae narrow, close, radiating, fuscous-brown.

Spores 5-6(7), in diameter, globose or slightly subglobose, conspicuously punctate, usually appearing verruculose. Basidia 16-20 × 6-7 µ, 2-4 -spored. Pleurocystidia none; cheilocystidia 26-36 × 6-10 µ, irregularly clavate or ventricose, at times subcapitate or with a slight neck. Cuticle of repent hyphae, bearing a turf of colorless, thick-walled, branched hyphae, 3-7 µ broad. Clamp connections present.

Habit, Habitat, and Distribution: Ecuador, February.

Material Studied: ECUADOR: Patouillard, type (FH), collected by Lagerheim, near Quito, Feb., 1892.

Observations: The notes on microscopic characters above are drawn from a study of the type. We have found no report of it from North America, but since it might occur in southern Florida or in the West Indies, we include it here. Its larger spores and distant gills separate it from applanatus. Its gill-spacing and floccose-puberulent pileus distinguish it from malachius.

Then again, there are three variations as well, at least one of the names of which seems to extend the species’ range far beyond Ecuador.

Crepidotus quitensis var. basicrinitus Singer
Crepidotus quitensis var. philippinensis Pat.
Crepidotus quitensis var. quitensis Pat.

I’m not having so much luck locating descriptions for those.

Segun la literatura, el C. quitensis se encuentra a grandes alturas en Ecuador, pero este ejemplar fue encontrado a casi nivel del mar, en un bosque tropical humedo. Puede tratarse de una especie parecida de Crepidotus.
