FIGURE 1 in Polyphasic characterization of Trichocoleus desertorum sp. nov. (Pseudanabaenales, Cyanobacteria) from desert soils and phylogenetic placement of the genus Trichocoleus

FIGURE 1. Morphological variability of the type population of T. desertorum (ATA4-8). A. Multiple trichomes in a sheath. B. Short trichome with conical apical cells. C. Different shapes of apical cells and tapering of trichome. D. Granules in cells (arrows). E–F. Variable cell lengths and sheath properties. G. Short trichomes with pointed apical cells and vivid cyan spots in cells, senescent culture. H. Necridium (arrow). I. Cyan spots in young trichome. Scale = 10 µm (A at lower magnification, B–I share the scale bar from B).
