Etymology: (Gk.) from “atractos”, spindle-like; “-sporo”, spore; “-cybe”: head (mushroom), that is a “Clitocybe” with fusiform spores.

Diagnosis: Stipitate basidiomata, appearing isolated or in groups. Pileus convex to flat-convex, rarely compressed at the center, sometimes with an obtuse central umbo, glabrous, pale gray to grayish brown. Lamellae adnate to subdecurrent, grayish to grayish buff, with lamellulae. Stipe central, concolorous with the pileus, whitish at the base. Pileipellis as a cutis.
