um. Sessile
and plasmodiocarpous forms do occur with the typical stipitate phase,
but may be regarded here as elsewhere as indicative of incomplete
development. Plasmodium cream-colored, or pale yellow.

Sporangia globose or ellipsoid, .7-1 mm., pale iridescent, stipitate;
peridium thin with slight calcareous deposits, rugulose, opening
irregularly, white; stipe long flaccid, straw-colored; capillitium an
elegant uniform net, its threads stiffened by slight deposits of lime,
the nodes little thickened, badhamioid; spores free, dusky with a shade
of violet, minutely spinulose, about 10 mu.

This beautiful species closely resembles some forms of _B. utricularis_
from which it differs chiefly in its unclustered smooth spores. _B.
foliicola_ as recognized here is hardly more than a smaller,
short-stemmed form of this; see species next following.

Not rare in the eastern United States and Canada; Iowa. Seems to take
the place of _B. capsulifera_ of Europe.

10. BADHAMIA FOLIICOLA _Lister_.

1911. _Badhamia foliicola_ List., _Mycetozoa, 2nd ed._, p. 34.

"Plasmodium orange." Sporangia smaller, about .5-.6 mm., globose or
ellipsoidal, iridescent-gray, stipitate or sessile, the peridium thin,
rugulose, sparingly calcareous, when empty white; the stipe when present
short but yellowish, of the flaccid sort; capillitium badhamioid; spores
free, delicately spinulescent, dusky-violaceous, about 12-13 mu.

This has been so far collected but once, on the shores of Lake Okoboji.
It was developed, no doubt, on the natural debris of a bur-oak prairie
border, and went to fruit on the leaves, stems, and fruiting spikes of a
species of _Setaria_. It may prove to be different from the _B.
foliicola_ of Europe; future collections and study must reveal that.
Meantime it seems wi
