Flora, 1885, p. 271 (1855).
Badhamia panicea, Rost. (figs. 74—76).
Sporangia gregarious on a thin hypothallus, sessile on a
broad or narrow base, globose or irregularly angular from mutual
pressure, wall thin, often iridescent, studded all over with innate,
detached, irregular patches of lime, the whole with a grey tint ;
capillitium very dense, snow-wbite, knots large, branched, connected
by thick bands, every part densely filled with granules
of lime; spores free, or with an indication of being originally
in clusters, globose, very minutely verruculose, dull violet, or
brownish-purple, 9—12 g diameter.

Plasmodium white. Sporangia up to 1 mm. diameter, generally
crowded and forming dense pale grey patches. Closely resembling
superficially Badhamia macrocarpa, but distinguished
by tbe coarser capillitium having every part crowded with lime,
tbe much smaller warts on the epispore, and the absence of
rugulose veins on the sporangial wall.

all over, dingy lilac-brown, 9—12 g diameter.

The examination of a large series of tbe three species given
as synonyms above, shows every shade of transition from one
to another. When sessile tbe sporangia are globose or irregular
from mutual pressure ; when stipitate, usually more or less
obovate or irregular. The amount of lime present on the wall
varies considerably ; when abundant, tbe surface is usually grey
and opaque ; wben scanty, iridescent. The clustered stems are
usually very slender and decumbent, and the clusters of sporangia
are sometimes pendulous. The capillitium is snow-wbite.
Tbe distinctive features of the species as defined above are the
globose spores warted all over, and the smooth wall of tbe
