FIGURE 7. Features of Hagiwaraea irregularibrachiatum (Krug 6–5A). A. Streamed aggregation of thin streams and dense center, with short secondary unfinished streams (forked), sometimes anastomosed at the end, small circles are microcysts, B. Early (above) and later aggregations with elongated coremiform sorogens in a cluster (below), C. Mature cluster of whorled sorocarps (including a late sorogen), some appear coremiform (left), others are decumbent and become prostrate (right), abundant microcysts within and surrounding the cluster, D. Solitary branched sorocarp, each branch may hold 1 to 4 whorls, or two groups of few whorls, E. Four models of bases: clavate, of several rounded enlarged cells of a solitary sorocarp (above left), coremiform bases consisting of one tier of cells, these are very uniform and rest on a dark cushion of dense slime (above, right), curved base with a stolon also angled (below left), curved base with protruding cells and a dense matrix of slime; in all cases, sorophores above the basal termina consist of one tier of cells, F. Model of a whorl, with its node and two curved branches, one is broken, a collapsed cell sustained on the other side by a cellular mass and slime (left), G. Microcysts, H. Capsulated small and broad spores with polar to subpolar unconsolidated granules, sometimes granules are widely scattered within the spore body, also with tiny vacuoles. Bars: A–B = 100 μm, C–D = 200 μm, E–F = 20 μm, G = 4 μm, H = 6 μm.
