and bands, 10-12 mu.

Generally distinguishable by its unusually large calcareous, white
sporangia. The peridia are strongly calcareous, shell-like in texture.
In some cases the color is tinted with rose.

This species is very near _B. capsulifera_ as recognized in the United
States. When white the Colorado material corresponds almost exactly with
the forms collected in Iowa, and regarded as representing the species
just named. The Colorado gatherings are more strongly calcareous and the
spores sometimes present the variations named. "The Colorado phase of
the American form."

Sporangia gregarious, globose, large, stipitate, iridescent-gray; the
peridium thin, translucent, and containing but little calcareous
deposits, smooth or slightly rugulose; stipe very short, but generally
distinct, black or very dark brown; hypothallus none; capillitium a
network of large meshes with expanded nodes, prominent, white,
persistent after the spores have been blown away; spore-mass deep brown;
spores adherent as in _B. capsulifera_, marked in much the same way, and
about the same size, 10-12.5 mu

Distinguished by its short, dark, stipe and adherent spores.

Not common. New England, Pennsylvania, Ohio, Maryland, South Carolina,
Wisconsin, Iowa.

Sporangia globose, sub-globose, or obconical, sessile, gregarious or
more or less clustered, supported by a thin, continuous, transparent
hypothallus; the peridium smooth pale, lilac-brown without, white
within; stipe none, although some sporangia have a narrowed base;
columella none, the pseudo-columella formed by a more densely aggregated
capillitium near the base; capillitium dens
