Cavenderia aureostabilis (TH10B). a Ample large streamed radiate aggregation with thin streams, separately, some brushy streams (left), smaller aggregations with shorter sided lobed streams (right). b Early highly migrating sorogens that leave traces of cells and slime, the tallest with stalk formation at its end (above, left to right), solitary late sorogen with a disk base and traces of early streams (non-migratory, below, left), early late sorogen that changes direction while migrating, becomes very elongated (below, right). c Late bifurcate sorogen with its ample cone to bell-shaped disk base (left), two young small sorocarps sharing a disk base (right). d Two clustered collapsed sorocarps, one continues a stoloniferous migration and the other not (left), firstly slender to weaving solitary unbranched sorocarp, well directed (center, left), a common stoloniferous habit of a late sorogen (center), two solitary unbranched mature sorocarps, one collapses and refruits, the other curved and weaving when aged (right). e Round base within a dense cone to bell-shaped regular matrix of slime that ends as an expanded prominent and regular disk, a cushion of differential slime below the base is attached to the substrate by thin inconspicuous fibers of sheath, the disk progressively filled in with small polygonal cells that covers all the body mass (left), clavate base with a protruding cell, the disk is omitted (center), shortly digitate base within the bell- to disk-shaped slime structure (right). f Simple one-celled tip holding a mass of rather undifferentiated cells and slime (above), curved simple tip with abundant dense slime (center), flexuous multi-piliform tip, all terminal cells are small. g Large narrow elliptical spores with irregular large consolidated PG, halos present, with vacuoles and small granules dispersed, a spore-cage (below, right). h Myxamoeba with multiple small-medium vacuoles. Scale bars: a, b: 300 μm; c, d: 0.5 mm; e: 25 μm; f: 10 μm; g: 6 μm; h: 10 μm
