FIGURE 10. Features of Raperostelium cymosum important for identification. A. Minute aggregations at different stages of progress: early-mature aggregation with short anastomosed streams that cover almost the whole area surrounding the centers (above, left), cupuliform, button-like pseudoplasmodium with a tiny very early sorogen (above, right), three closer late aggregations, almost mound-like, with one to three streams (below, right); streams are very short and ample, expanded, lobed, flattened progressively, inconspicuous and open at the end to incoming myxamoebae, B. Three tight clusters of sorogens, early curved, irregular sorogens that rise up in close contact each other, bend over and separate at tips, in this case, almost at the same time, C. Early and late solitary sorogens (above, right and left) and mature fruiting bodies tightly clustered; a majority of sorocarps have well separated sorophores and sori, one is coremiform (center, left), two clusters show the on-going production of early sorogens at base (below, left), sorophores are of different heights, delicate, irregular, curved, somewhat broken, sometimes branched, few in number; sori are globose, one sorocarp has a collapsed its sorus, D. Large elliptical, mostly reniform spores with conspicuous consolidated polar to subpolar granules. Bars: A = 50 μm, B = 50 μm, C = 350 μm, D = 6 μm.
