at the center to form a
pseudo-columella; spores not adhering, brownish-purple ellipsoidal, 8 x
10-10 x 15 mu.

Reported from Bohemia, England, Pennsylvania.

2. BADHAMIA VERSICOLOR _Lister_.

1901. _Badhamia versicolor_ List., _Jour. Bot._, XXXIX., p. 81.
1911. _Badhamia versicolor_ List., _Mycetozoa 2nd ed._, p. 35.

Sporangia scattered or clustered, minute, .3-.5 mm., grey or
flesh-colored, sessile, the calcareous deposits slight; capillitium
white or apricot-colored; spores ovoid, 8 x 10-9 x 12 mu, clustered,
purplish, and warted at the broader end, elsewhere colorless and smooth.

This little species, as it comes to us, is grey, very uneven in size,
.2-.5 mm. and generally irregular in form and habit, perhaps scarce
mature. The capillitium is white, physaroid. The spores furnish the
distinguishing character. Sometimes globose, about 9-10. They are most
of them definitely and permanently affected in shape by the fact of
cluster-association, narrower in the direction of the cluster center.
The indications are that these may become globose with maturity.

3. BADHAMIA DECIPIENS (_Curtis_) _Berk._

1848. _Physarum decipiens_ Curtis, _Am. Jour. Sci._, VI., p. 352.
1873. _Badhamia decipiens_ Berk., _Grev._, II., p. 66.
1873. _Physarum chrysotrichum_ Berk. & C., Grev. II., p. 66.
1876. _Badhamia chrysotricha_ (Berk. & C.) Rost., _App._, p. 4.

Sporangia gregarious, depressed-spherical or ovate, sessile,
occasionally plasmodiocarpous, dull yellow, roughened by the rather
large numerous calcareous scales; columella none; capillitium dull
orange, strongly calcareous, only slightly widened at the nodes;
spore-mass black; spores pale violet, minutely spinulose, free, 10-12 mu.

Among badhamias this and the next species are at once distinguished by
the color. If the brief description (_Grev._, II., p. 66) can be
regarded as defining anything, this is the same as _P. chrysotrichum_
Berk. & C. It resembles somewhat _P. serpula_ Morg., but differs
externally in color and in the surface scales, which are not perceptible
in the _Physarum_. The present species also resembles _Cienkowskia
reticulata_ (Schw.) Rost., but has a different capillitium. See under
that species.

Chiefly eastern and American. New England, Pennsylvania, Ohio, South
Carolina; reported recently also from Sweden and Germany.
