Cavenderia protodigitata (TH18BA). a Group of small to medium-sized aggregations (left, from above) and clustered late aggregation with short blocky streams (from the side, above, right) and small mounds (below, right). b A central main early sorogen surrounded by smaller settled sorogens (above), a series of development stages of solitary late sorogens from left to right, with migrating small sorogens (center), two clusters of early sorogens (below, left) and a loose cluster of sorogens at different stages of development (below, right). c Solitary unbranched sorocarp (above, left) and three sorocarps, two in a loose cluster and one with a stoloniferous habit (below, right), branches are scarce. d Bases, one round celled (left), two bases terminating in clavate to apron-like cells, one shows an irregular sorophore with a mass of dense granulated mucilage (center, left), the other shows a dense mucilage as a crampon below the base and within a lobulate slime with large dispersed cells (center, right), a tight cluster of lower sorophores (right). e Variable tips, one to two celled tips with dense slime (left), flexuous enlarged tip cell (center), two flexuous multipiliform tips, one is ampulla-shaped (right). f Elliptical slightly large spores with consolidated PG, one commonly large and with a halo. g Myxamoeba. Scale bars: a, b: 300 μm; c: 0.5 mm; d, e: 20 μm; f: 5 μm; g: 10 μm
