n. Soc._, XXI., p. 153.
1863. _Badhamia inaurata_ Currey, _Trans. Linn. Soc._, XXIV., p. 156.
1873. _Badhamia nitens_ Berk., Rost., _Mon. App._, p. 3.

Sporangia gregarious or closely crowded, globose or depressed-globose,
.5-1 mm. in diameter, yellow or greenish yellow, rugulose, sessile;
capillitium yellow, forming an open net with occasional thickenings at
the nodes; spores clustered, delicately roughened, violaceous-brown,
10-12 mu.

This much resembles the preceding species except in the clustered
spores, and more commonly aggregate habit. The spores, as usual when
clustered, are conspicuously echinulate on the outer side. This did not
escape the notice of the author of the species, _op. cit._

Colorado, Oregon. Reported from West Indies, Ceylon, various parts of
Europe.

5. BADHAMIA PANICEA (Fries) Rost.

1829. _Physarum paniceum_ Fries, _Syst. Myc._, III., p. 141.
1873. _Badhamia panicea_ (Fr.) Rost., Fuckel, _Sym. Myc. Nachtr._,
2, p. 71.

Sporangia gregarious or aggregated in closely compacted clusters,
globose or hemispherical, sessile, the peridium thin, transparent,
thickly dotted with white calcareous scales; stipe none; columella none,
although a pseudo-columella sometimes appears, formed by a more dense
development of the capillitium near the centre of the sporangium below;
capillitium abundantly developed, quite uniformly thickened, but showing
an occasional delicate connecting thread, the nodes also somewhat
flattened and enlarged; spore-mass black; spores by transmitted light,
bright violaceous-brown, minutely roughened, 10-13 mu. Plasmodium is said
to be white.

In America this seems to be a purely western species. Specimens are
before us from western Iowa and from Colorado, South Dakota, Nevada, and
Southern California. It is very well marked, though liable perhaps to be
mistaken at first sight for sessile phases of _P. notabile_ or _P.
cinereum_. The capillitium is, however, at once determinative. Colorado;
_Bethel_. Europe generally.

6. BADHAMIA AFFINIS _Rost._

1875. BADHAMIA AFFINIS Rost., _Mon._, p. 143.

Sporangia aggregated, cespitose and sessile, or sometimes stipitate,
depressed above, flat or umbilicate below, the wall grayish white,
rugulose, and more or less calcareous-scaly; the stipe when present
erect or sometimes nodding, black or brownish black; hypothallus scanty;
columella none; capillitium not abundant, white, the nodes somewhat
expanded;
