FIGURE 12. Features of Raperostelium crispum important for identification. A. Irregular asymmetrical small aggregation with typical curled, unfinished streams, streams soon anastomose, leaving very small empty areas that sometimes give the appearance of acute angles; stream diameters vary from very thin to relatively wide at any point of their length, leaving minute masses of streamed pseudoplasmodia progressively isolated (above), larger streamed pseudoplasmodia fragment and form irregular close, sometimes connected, mounds, the peripheral ones are open to incoming myxamoebae (below), B. Clustered and solitary sorocarps with the remaining expanded formation of curled streams at their bases, often streams are annular, sorophores are curved, broken, sori globose, small to large, C. Two late pseudoplasmodia with a very early sorogen (right) and with a bifid early-late sorogen (left), small pseudoplasmodia that surround the main mass soon condense into mounds, D. Small short elliptical or oblong spores with consolidated granules at the poles. Bars: A = 40 μm, B = 300 μm, C = 150 μm, D = 6 μm.
