, coarse reticulation, violaceous, pale,
10-12 mu.
This is a very interesting species closely related to the preceding from
which it differs chiefly in the reticulation and generally more uniform
character of the spores. The author hesitated about the generic
reference, finally referring it to _Diachaea_ despite the lack of
calcium, because it was sessile and had a peridium rather more
persistent than is usual in comatrichas. But the presence of lime in
stipe and columella is an essential element in the diagnosis of
_Diachaea_, while length of stem is everywhere variable in stipitate
forms of every genus, and the persistence of the peridium is also an
uncertain factor; hangs on long in _C. typhoides_, _e. g._
On dead twigs, etc.--Philadelphia,--_Mr. Bilgram_; New Hampshire.

Sporangia semi-erect, close crowded in tufts two inches in diameter,
ferruginous, from a dark brown hypothallus, sessile or short stipitate;
columella weak, crooked, percurrent, generally enlarged irregularly at
the apex; capillitium of few, slender, brown branches which anastomose
sparsely and irregularly as in _C. irregularis_, and present when freed
from spores the same chenille-like appearance; spore-mass ferruginous
brown; spores by transmitted light bright reddish brown, minutely
warted, 8-10 mu.
"Growing on old wood and bark of Oak, Willow, etc. The component
sporangia 5-10 mm. in length. The early appearance is much like that of
a species of _Stemonitis_, but the mature stage is a great mass of
spores with scanty capillitium, as in _Reticularia_; the columellas,
however, are genuine and not adjacent portions of wall grown
together."--_Professor Morgan._
Professor Morgan's herbarium material is at hand for study. It meets his
description, needless to say, very generally. In what remains of the
type the membranous connections are obscure; in fact the relation of
such peridial (?) fragments to the capillitium in any way, is no longer
evident. But in any event the colony does not impress one as something
prematurely or improperly developed, a stemonitis gone begging;--nothing
