FIGURE 3. Features of Cavenderia minima (Eden 1). A. Irregular small aggregation with few ample streams, the streams have lobular margins and ends, open to incoming myxamoebae; generally, one smaller stream appears surmounted over the body of the others, the center is elevated and granulose (above), three minute and irregular mound-like aggregations, with a flattened edge of incoming myxamoebae (below), B. A sequence of development of small solitary early sorogens from left to right, a very early sorogen rises up from the center of a cupuliform pseudoplasmodium, one to three old flattened streams appear as clouds of myxamoebae (left) and may remain until further development, a sorus-like, rounded terminus, sorogen may be formed (right), C. A tight cluster of sorocarps with a late small sorogen and a mature sorocarp with rising up tiny masses of pseudoplasmodia and slime (right), on the left a solitary decumbent marginal sorocarp has collapsed, with a stoloniferous habit; at the center a curved sorophore with no sorus; the relicts of three ample streams remain as clouds of myxamoebae and mucilage at bases, D. Two solitary unbranched sorocarps, straight prone with a globoid sorus (left) and a sorocarp with two curves of the sorophore, with a globose small sorus, bases inconspicuous but surrounded by granules, slime, and relicts of the pseudoplasmodia, E. Three bases with one tier of cells: clavate, with smaller terminal cell, the sheath is cone-like (left), curved, with a curved enlarged terminal cell (center), a base with its last four cells enlarged, showing the mucilage and a small mass of more dense and darker mucilage (right), F. Different simple one-celled tips: with an amorphous cell (left), three with an enlarged granulated cell and/or abundant slime (center), with a piliform elongated terminus (right); the last sorophore segment is always flexuous, most of tips are curved at the end, G. Myxamoebae with an enlarged vacuole, H. Elliptical irregular spores with clusters of consolidated and unconsolidated (spaced) granules mostly at poles, one cluster of granules is larger than the opposite one, halos are common around the clusters of granules, I. Spore break-line and the open spore capsule (below) in two halves. Bars: A–B = 50 μm, C–D = 100 μm, E = 15 μm, F = 3 μm, G = 10 μm, H–I = 6 μm.
