Roholtiella bashkiriorum Gaysina et Bohunická , spec. nov. ( Figs. 2A–O View FIGURE 2 )
Morphologically most similar to R. fluviatilis , from which it differs by living on damp to dry soil rather than in rivers or water’s edge of rivers. Differing from R. mojaviensis in occurring in temperate, mesic soils and having olive coloration rather than deep blue-green coloration. Differing from all other species in the sequence of the flanking regions of the Box-B and V3 helices of the 16S-23S ITS region ( Fig. 5 View FIGURE 5 ).
Type: — Russia. Macroscopic growth of algae and cyanobacteria on the path near river Ik on the edge of the village Bolsheustikinskoye, Republic of Bashkortostan, L.A. Gaysina, August 2010 (holotype: CBFS! A-036-1). Reference strain: CCALA 1057.
Description: —Thallus flat spreading, slightly growing into the substrate, olive-green to brown, with rugged surface ( Nostoc -like) when old. Filaments short to long, single ( Figs. 2F, J View FIGURE 2 ) or more rarely double ( Fig. 2I View FIGURE 2 ) false branched. Sheath thin, attached ( Figs. 2J, M, N View FIGURE 2 ) or diffluent, colorless, trichomes sometimes curled inside the sheath. Trichomes constricted at crosswalls, not tapered to distinctly gradually tapered without swollen base ( Figs. 2A, B, C, E, F View FIGURE 2 ), 6.6–9.8 μm wide in the widest portions. Cells shorter than wide to isodiametric, barrel-shaped to rounded, with smooth or finely granulated content, olive-green, grey-green or orange-green, 2.1–8.5 μm long. End cells conical rounded, 3.3–6.9 μm wide, 3.6–7.2 μm long ( Figs. 2B, D–F View FIGURE 2 ). Heterocytes terminal hemispherical ( Figs. 2 B, F View FIGURE 2 ) or intercalary cylindrical and often hemispherical in pairs before the filament breakage ( Fig. 2K View FIGURE 2 ), yellow, 4.1–8.2 μm wide, 2.5–7.4 μm long. Arthrospores or short rows of arthrospores released from the ends of the filaments ( Figs. 2G, H, M–O View FIGURE 2 ), spherical compressed to almost spherical, 6.2–10.5 μm wide and 4.9–9.0 μm long. Hormogonia 2.5–5.2 μm wide, 1.6–3.8 μm long ( Fig. 2A View FIGURE 2 ).
Habitat: —soil.
Etymology: — bashkiriorum = of the Bashkirs, named for the Bashkir people of the Republic of Bashkortostan, Russia.
Other strain: —CCALA 1059 (CBFS! A-037-1)
