2-GEASTER DELICATUS. 
Outer peridium thin, smooth, firm, hygroscopic, cut (about 2 /z 
deep) to 8-10 segments. Spreading when moist, incurved when dry. 
Inner peridium subglobose, opening by a plane, indefinite aperture. 
Columella none. Capillitium slender, interwoven, simple or sometimes 
slightly branched near the end, slightly thinner than the spores. 
Spores globose, minutely war ted, 5-6 me. 
This elegant little species is known only from the Northwest. 
It was described by Prof. Morgan from specimens received from Ne¬ 
braska. Hollos considers this plant a synonym of G. lageniformis of 
which he sends specimens. (*) It seems to me however that the plants 
while very close are different. Lageniformis has a protruding mouth. 
Delicatus the mouth is indefinite, plane, merely an aperture, the same 
as G. hygrometricus. We admit that the two plants are - very close, 
probably the same, but for the present would keep them distinct. Had 
Morgan had access to Vittadini’s figure we should not have blamed 
him for describing the plant he met as a new species. The figure is an
