Overview | |
Cultivated on dilute hay infusion or 0.5% glucose, 0.1 % peptone agar in association with a mixed flora consisting of Klebsiella pneumoniae and Dematium nigrum at 25-30 C. Sorocarps arise from migrating pseudoplasmodia, very small, often solitary, but typically clustered to form coremiform fructifications, variable in number, rarely up to nine or ten per cluster, commonly 350-650 µm in height. Sorophores erect, tapered, appressed throughout most of their length, diverging terminally to bear whitish or hyaline globose sori 40-90 µm in diam. Spores elliptical to reniform, usually 6.0-7.5 x 3.0-3.5 µm granules often evident but not consistently polar. Cell aggregations typically radial in pattern, often 5-10 mm in diam., producing few to many long, thin, and fragile migrating pseudoplasmodia up to 1.0 cm in length, not phototropic. Myxamoebae comparatively small, usually 8-12 x 5.0-7.5 µm, sometimes larger or smaller. Unaggregated cells form microcysts, globose or nearly so, 4.0-6.5 µm in diam.; macrocysts reported but not observed.
