Gregarious, sessile, 3{-114 mm. diam., at first globose, then 
expanding to shallow cup-shaped, with the short-fimbriate margin 
narrowly incurved, outside dark brown, appressed-hirsute, when 
dry the opposite margins are incurved in a hysteriiform manner ; 
the substance of the ascoma is carnose-coriaceous; disk concave, 
dull white with a distinct rosy tint; asci clavate-cylindrical, 40-45 
6-7 4; paraphyses stout, cylindrical, about as long as the asci,

CENANGIUM ALPINUM E. & E. 
On decorticated limbs of Ades, San Juan Mts., Colo., alt.

the paler subfimbriate-floccose incurved margin more tardily so ;
