Morgan, A.P. 1887. The genus Geaster. American Naturalist 21: 1027-1028.
-Outer peridium thick, multifid; the segments (eight to ten) reflexed, whitish below, rufescent within. Inner peridium globose, subpedicellate, verrucose, gray, or brownish, the mouth conic, sulcate-plicate, in a circular, marginate disk. Spores globose, verruculose, brown, .0055-.007 mm. in diameter.
Growing in clusters, at first half immersed in the soil, on the open prairie about Lincoln, Neb. Sent by Prof. Charles E. Bessey.
Inner peridium three-eighths to three-fourths of an inch in diameter, the expanded segments one to two inches. The outer peridium is concave or vaulted underneath, with the segments often inflexed at the tip, as in G. bryantii and G. limbatus; it also has the same fibrillose stratum beneath binding it to the soil; when this is cleared away it leaves a smooth, whitish outer surface. In most of the dried specimens the inner peridium is distinctly pedicellate. The peculiar feature of this species, however, is the minute, scaly or granulose warts which invest the surface of the inner peridium; there is no other species with a similar surface, unless it be the G. granulosus Fuckel, which is described as "covered with a white granulose powder." Moreover, it has a filamentous peristome, and belongs among the Fimbriati, while our species belongs to the Striati of Dr. De Toni's arrangement.
