A rare or very seldom recorded Agaricus, looking at first sight like a field mushroom. It is characterized by clavate cheilocystidia and rather larger spores than most others of the genus; but especially by the upwardly directed sheath encasing the stem and arising from the sharply pointed base. The cottony ring at the juncture of the sheath rim and stem is ephemeral. The sheathing structure is rather like a close-fitting volva.
