verrucose, gray or brownish, the mouth conic, sulcate-plicate, in a cir¬ 
cular, marginate disk; spores globose, verruculose, brown, .0055—.007 
millim. in diameter. Growing in clusters, at first half immersed in the soil, 
on the open prairie about Lincoln, Neb. Sent by Prof. Chas. E. Bessev.

‘'Inner peridium three eighths to three-fourths of an inch in diam¬ 
eter, the expanded segments one to two inches; the outer peridium 
is concave or vaulted underneath, with the segments often indexed at 
the tip, as in G. bn/antii and G. limbatus; it also has the same fibrillose 
stratum beneath, binding it to the soil; when this is cleared aw^ay, it 
leaves a smooth, w r hitish 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 powuier” Moreover, it has a filamentous 
peristome, and belongs among the FimbnaU , while our species belongs to 
the Striati of Dr. De Toni’s arrangement.

“Outer peridium thin, multifid; the segments (six to ten) unequal, 
revolute, whitish below, alutaceous within; inner peridium depressed- 
globose. sessile, puberulent, pallid, the mouth lacerate; spores globose, 
verruculose, fuscous, .005—.006 millim. in diameter. Growing on the 
prairie around Lincoln, Neb. Sent by Prof. Charles E. Bessey. 
“Inner peridium one-fourth to one-half of an inch in diameter, the 
expanded segments an inch or more. The segments,when fresh or w^et, are 
strongly revolute, and become indexed when dry, after the manner of G. 
hygrometricus; they are nearly papyraceous, the inner, fleshy stratum 
being remarkably thin; the color outside is whitish or glaucous and the 
external surface is very smooth. There is no determinate circular areola 
to the inner peridium and the mouth is stellately lacerate or sometimes a 
mere slit or puncture. The nearest relative would appear to be G. bovista , 
Klotsch, from which it differs in several particulars; it belongs to the 
same section, the Exaveolnti , of Dr. De Toni’s monograph.”
