es small, yellow; spores nearly smooth,
violaceous-brown, 5-6 mu.
This unique form is near the fuligos which it resembles, especially when
sessile, in its intricate sporangia. The spores also are those of the
common _Fuligo septica_. The habit is however entirely different. Mr.
Fetch describes clusters in Ceylon, hanging free, four to six cm. in
length!

Sporangia simple; peridial wall simple, thin, breaking irregularly;
capillitium formed of abundant, richly anastomosing tubules, filled
throughout their entire length with calcareous granules; the nodes often
feebly represented; stipe poorly developed or wanting entirely;
columella, except in forms sometimes assigned to the sub-genus
_Scyphium_, poorly developed or none; spores frequently adherent in
clusters.
The whole genus calls for careful and protracted study; and the
present so-called species are like something new on the world;
as full of vagaries as though but just entered upon their
phylogenetic race.
This genus is closely related to _Physarum_, but differs in having the
capillitium calcareous throughout. Forms occur and are included here, in
which the capillitium, especially in some parts, is physarum-like,
physaroid. Nevertheless, the distinctions hold good as a rule, and are
at once diagnostic.
In capillitial differentiation the badhamias are definite and beautiful.
The net in a typical species, as _B. papaveracea_, is throughout
uniformly evenly tubular, the calcareous deposits delicate in the
extreme, presenting, as the spores disappear, an elegant trabecular
structure as if to support the persisting peridium if not the original
content. In other forms the capillitium is physaroid, with swollen
nodes, but heavily calcareous but not quite throughout. _Badhamia_,
_Physarum_, _Tilmadoche_, _Craterium_ present a consistent group, of
which _Physarum_ is the generalized expression.
Berkeley's idea of the genus was expressed as follows: "Peridium naked
or furfuraceous. Spores in groups, enclosed, at first, in a hyaline
sack." Rostafinski, while accepting Berkeley's generic name, redefined
it, emphasized the calcareous capillitium, and made reference to the
spore-adherence only to assert that Berkeley's description was, in this
particular, based on mistaken observation. In some
