Geastrum australe Berk. 1859

Plants superficial, at first ovate and acuminate, becoming expanded when to 7 cm. across. Exoperidium saccate, split to about the middle into 6-8 broad, equal, acuminate rays, which are expanded or with tips involute; fleshy layer bay brown or chestnut brown, adnate, continuous when fresh, becoming rimose; exterior free from debris, ochraceous, glabrous; base plane, convex or occasionally umbilicate, marked with a prominent umbilical scar. Endoperidium sessile, to 2 cm. diameter, ochraceous or pallid tan, glabrous, smooth; peristome fibrillose, mammose, seated on a broad, silky, slightly depressed concolorous zone, which is occasionally outlined by a slightly raised margin. Gleba ferruginous; pseudo-columella inevident. Spores globose, 7.5-9um diameter, epispore tinted, 1um thick, covered with long, flat-topped spines closely packed together and 1.5-2um in length. The species resembles G.triplex in growth habit, peristome characters and smooth exterior of the exoperidium. It differs in the ochraceous endoperidium and much larger spores, the latter being so distinctive as to make identification easy.
