Cavenderia bhumiboliana (TH11CX). a Late violaceum-type aggregations, with irregular mounds or short thick streams. b Clustered early sorogens (above, left), solitary early sorogens (above, right), a crowded cluster of early and late sorogens, the mature central sorocarp has collapsed and its sorus has refruited (below). c Group of very curved sorocarps, two solitary but proximal fruiting bodies with few or no branches (left), two base-joined sorocarps in a cluster and a proximal one with stoloniferous habit (right). d Bases round to plane with sharp digitations (above), a single celled base and a clavate base with cells below the base (center), a shortly digitate base with sharp terminal cell (below). e Six variable tips, flexuous with piliform ends, one celled holding a mass of mucilage and rather undifferentiated cells, a thin elongated flexuous cell, an ampulla piliform cell and a short capitate single cell. f Broad elliptical regular spores with irregular consolidated PG. g Myxamoebae. Scale bars: a,b: 300 μm; c: 0.5 mm; d: 20 μm; e: 10 μm; f: 6 μm; g: 10 μm
