quent in collections (usually under the name fornicatus). Romell 
writes me that it is the most common Geaster of Sweden and hence 
must have been known to Fries, though why he describes the mouth 
as “sulcate’ ’ is strange if he had observed the plant instead of Schaeffer’s 
inaccurate figure. We have never seen but one collection of the plant 
from this country made by G. E. Morris, of Waltham, Mass

EXOPERIDIUM SACCATE.—MOUTH EVEN. 
In all the previous species with even mouths the exoperidium when expan¬ 
ded is revolute away from the inner peridium, but in this subsection the base re¬ 
mains as a cup holding the inner peridium. We can readily conceive however, 
that this would not hold true in all cases, but it is the usual condition that we find 
in specimens. Fimbriatus of Europe while saccate in all our specimens is not put 
into the saccate section by Fries. Lageniformis while we have never seen specimens 
not saccate, we have of the closely related plant Morganii and conceive that if 
perfectly expanded this would become revolute (as Fig. 32). Velutinus and 
saccatus are however truly saccate species. 
KEY TO SPECIES. 
Unexpanded plant globose, 
Exoperidium splitting into two layers, 
velutinate,...(19) velutinus. 
smooth,.(20) fimbriatus. 
Exoperidium not separating,. (21) saccatus. 
Unexpanded plant acute,.(22) lageniformis. 
19—GEASTER VELUTINUS. 
Unexpanded plants globose, sometimes slightly pointed at apex. 
Mycelium basal. Outer layer rigid, membranaceous, firm, light color in 
the American plant; dark, almost black in the Samoan. Surface cov¬ 
ered with short, dense, appressed velumen in the American plant so 
short that to the eye the surface appears simply dull and rough, but 
its nature is readily seen under a glass of low power. In the Samoan 
plant the velumen is longer and plant appears to the eye as densely 
tomentose. The outer layer separates from the inner as the plant ex¬ 
pands and in mature specimens is usually par tty free. The thickness 
and texture of the two layers is about the same. Fleshy layer dark 
reddish brown when dry, a thin adnate layer. Inner peridium sessile, 
dark colored, subglobose with a broad base and pointed mouth. Mouth 
even, marked with a definite circular light-colored basal zone. Colu¬ 
mella elongated, clavate. Spores globose, almost smooth, small, 
2 -3 12 me.
