First recoginzed in Colombia (Mycologia 83: 464. 1991), we have found this Phaeocollybia at a few sites near Cerro de la Muerte. It has a viscid, glabrous, and conic pileus that starts out brown and fades with age, has a radish-like odor and bitter taste. Microscopically, it lacks clamp connections, the spores are generally ellipsoid and finely warty, and the cheilocystidia are subclavate to clavate (see line drawing below).
