C r a t e r i u m l e u c o c e p h a l u m , Rost. (figs. 298—301).
Sporangia stipitate, conico-oylindrical, pyriform or subglobose,
apex rounded and eventually hreahing away in a circumscissile
manner, upper portion of sporangium whitish and rough with
minute, inncde particles of lime which eventually fall away,
leaving minute pits in the wall, basal portion of sporangium
darh recldish-hrown, much wrinhled; capillitium dense, knots
large, irregular, numerous, usually aggregated in tbe centre to
form a columella, granules of lime colourless, yellow or brownish ;
spores globose, dull violet or brownish, minutely warted, the

Plasmodium yellow. Gregarious or scattered, 1'5—2 mm.
high, variable in form and length of stem, the upper convex
portion of tbe sporangium breaks away in a circumscissile
manner, there is not a differentiated lid as in C. milgare. The
present species is best characterized by tbe pale upper portion
of tbe sporangium being incrusted with minute particles of
white or yellowish lime, and also by the presence of numerous
circular discs sunk in tbe substance of tbe wall; these discs vary
