Phaeocollybia attenuata can be distinguished by its small size, conical, non-viscid, ochraceous to orangish brown cap, pinkish buff to pale lilac young gills, and a narrow cartilaginous stipe with ochraceous apex and reddish brown to black base. It is similar to Phaeocollybia californica, but it has a viscid cap when moist, white young gills, a thicker stipe and fruitbodies that grow in fasciculate clusters
