On the ground. Maungaroa.

Plants globose and submerged, becoming expanded when! to 3 cm. across. Exoperidium saccate, split to about the middle into 6-8 unequal, flaccid, bluntly pointed rays which are expanded or with the tips revolute; fleshy layer brown, continuous, adnate; exterior wholly covered with debris held by the adnate mycelial layer, which may partially flake away upon weathering; base convex, plane or concave. Endoperidium sessile, 5-10 mm. diameter, depressed globose, drying white or umber brown, glabrous, smooth. Stoma either an inconspicuous aperture with fibrous or lacerate margin, or defined by a slightly depressed concolorous or lighter zone, sometimes approaching the fibrillose condition. Gleba umber; pseudo-columella inevident. Spores globose, 3.5-4.5um diameter, epispore fuscous, 0.75 um thick, closely and finely verruculose. The species is differentiated by its small size, indefinite stoma, persistent mycelial layer and sessile endoperidium. Occasional plants possess an obscurely fibrillose peristome, when they approach G.saccatum, being then separated by the persistent mycelial layer. Two forms are present in the collections listed, separable only by the spores, those of one being 3.3-3.7um diameter, of the other 3.5-4.5um
