spores globose, minutely roughened, violet-brown, large, 16-17
mu.

Chiefly on moss, the pale ashen sporangia generally very small, mounted
on the tips of the leaves, sometimes sessile, sometimes with a distinct
black stipe in which case the peridium is distinctly umbilicate.
Specimens from Kansas referred here have the stipe pale, rugose, long,
about twice the sporangium; habitat bark.

Rare. New York, Ohio, Kansas; more recently reported from Scotland and
Japan.

There is nothing new to be added here; nor appears any other place to
which such material as we have may be referred. New collections no doubt
will one day appear, when the identity may, let us hope, be made secure.

Meantime we have a form closely related which may be entered as

BADHAMIA IOWENSIS _Macbr. n. s._

Sporangia gregarious or loosely scattered, depressed globose, .4-.6 mm.
in diameter, stipitate, grey, flecked by rather prominent but small
rounded calcareous scales: the stipe short, half the diameter of the
sporangium, black or very dark brown, without hypothallus but widening
above into a shallow expanded base for the sporangia; columella none:
capillitium dull yellow, sometimes white, strongly calcareous,
physaroid, heavy; spores free, dark brown in mass, pale violet by
transmitted light, minutely verruculose, the tiny warts in some areas
more densely placed, producing evident shadowy spots, 10-11 mu.

This interesting little species occurs on the lower surface of fallen
logs, blocks, etc., in colonies of considerable extent, hundreds of
sporangia in a place. The capillitium is comparable to that of _B.
decipiens_ or _B. panicea_; it is physaroid to the extent that an
occasional filament may be found non-calcic, and not typically
badhamioid as in _B. papaveracea_, _B. macrocarpa_. The sporangial base
persists, dark brown, bearing traces of the clumsy capillitium, but no
columella real or simulated. Blackhawk Co., Iowa; _communicavit Dr.
Jessie Parish_. See Plate XX., 1, 1 _a_, 1 _b_.

Reddish or roseate forms sometimes appear in colonies otherwise as
described. It differs from _B. affinis_ in the size and character of the
spores, in color and character of the capillitium, habit and surface
markings.
