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 × 10-9 × 12 µ, 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.
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 µ.
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.
