Plant gregarious, wholly white, about a line in height, fixed to the trichia
by a minute fimbriated base. Little head or peridiolum globose, opaque
(sometimes pellucid according to some authors), glabrous, confluent
with the sporidia, deliquescing on the application o f moisture. Stipes
solid, opaque, slender, equal, set with minute, pellucid, roundish processes

A pretty little species of Stilbum, discovered to be a native
of Britain by the B-ev. M. J. B e r k e l e y , an eager and successful
investigator of cryptogamous vegetables.
The genus Chordostylum of T o d e is distinguished from
Stilbum, hy its powdery deciduous peridiola, and unequal stipes.
