Sporangium stipitato, sphairico-depressed, plane, or slightly 
umbilicate below, greyish, covered with distinct, but closely 
arranged white innate flakes of lime ; stem equal to or longer 
than the sporangium, very thick, equal, brown, longitudinally 
rugulose, expanding into a broad dark-brown hypothallus, filled 
with masses of lime and organic matter ; capillitium absent, but 
when the sporangium is empty a brown spot is seen at the base, 
which corresponds to the apex of the stem ; capillitium dense, 
nodes few, large, angularly stellate, filled with colourless granules 
of lime, internodes elongated, slender ; spores dingy lilac, globose, 
very minutely verruculose, 15-16 fj. diam.

Sporangia globose, broadly ellipsoid, or a little flattened, 
stipitate or sessile, rarely elongated and flexuous or anastomosing, 
wall at first covered with a continuous snow white coat of lime, 
which soon becomes broken up into smooth minute patches, stem 
variable in length, white, containing lime, straight, brittle, 
slightly thinner upwards, longitudinally rugose, passing into a 
more or less evident hypothallus ; columella absent ; capillitium 
strongly developed, snow white, with numerous large irregularly 
branched knots, containing lime in small granules ; spores globose 
dingy lilac, rather coarsely warted, warts almost black, 9-12 y.

Sporangia subglobose, usually a little depressed below, stipitate 
or sessile, wall thin, with irregular, white, innate patches of lime, 
dehiscing irregularly ; stem usually longer than the sporangium, 
erect, slightly attenuated upwards, longitudinally rugulose, brown, 
paler above, passing into a dark hypothallus ; capillitium dense, 
colourless, anastomosing very irregularly, threads thin, often 
flattened at the angles, which rarely contain lime ; spores globose,
