Overview | |
Cultivated on low-nutrient substrates such as weak hay infusion or 0.05% lactose, 0.025% yeast extract agars in association with Klebsiella pneumoniae at 23-26 C. Sorocarps very delicate, gregarious, uncolored, erect or nearly so, consisting of unbranched, acellular sorophores commonly 750-1500 µm in length and ranging from 1.0-3.0 µm in diam. at the base to 0.5-1.0 µm at the summit. Sori terminal, globose, whitish to hyaline, mostly 30-55 µm in diam., sometimes less, rarely more. Spores globose, hyaline, commonly 5.0-7.0 µm in diam., thin-walled. Cell aggregations typically radiate, variable in size, commonly 1.0-1.5 mm in diam. and fruiting normally, sometimes much larger, up to 1.0 cm or more and usually nonfruiting; sorogens clavate to fusiform, commonly 125-225 µm in length. Myxamoebae variable in form and dimensions, uninucleate, with filose pseudopodia when moving freely, commonly 12-18 x 7.5-10 µm. Unaggregated myxamoebae may form globose microcysts, 5.0 to 8.5 µm in diam. Macrocysts not seen or reported.
