Plants globose, submerged, becoming superficial and expanded when to 5 cm. across. Exoperidium split to about the middle into 8-10 acute equal rays, which are expanded when wet, strongly involute when dry, folding over or under the endoperidium; fleshy layer umber, adnate, continuous, exterior covered with debris held by the adnate mycelial layer; base umbilicate. Endoperidium shortly pedicellate, depressed globose, to 15 mm. diameter, umber, coarsely and closely asperate. Peristome conical, acute, seated on a depressed zone, concolorous or darker. Gleba ferruginous or umber; pseudo-columella not seen. Spores globose or subglobose, 4-5.5um diameter, epispore pallid brown, 0.75um thick, closely and coarsely verrucose.The species so closely resembles the preceding (G. campestre) that separation is possible only on the smaller, differently warted spores.
