Consequently, we cannot confirm that it is indeed C. muscicola as named in the
SAG collection. This strain is available also in CCALA collection under no. 1010, GenBank accessions KF111150 and KF111151. Cylindrospermum pellucidum Johansen et Bohunická sp. nov. (Fig. 5, aa-aj) Thallus slimy to leathery, with star-like spreading filaments in bundles, blue-green in young cultures, becoming green to yellowish with age, with nacreous, shiny surface. Trichomes short or long, dispersed in a wide mucilage, flexuous, Ponatinib constricted at the cross walls, isopolar or heteropolar, motile, 2.7–4.7 μm wide. Vegetative cells cylindrical or slightly concave, isodiametric to longer than wide, pale blue-green, with parietal thylakoids, 3.0–5.6(8.3) μm long. End
cells rounded or conical. Heterocytes forming terminally after trichome fragmentation, solitary, unipored, spherical to elongated or conical, with tan smooth content, (3.0)5.0–9.0(12.4) μm long, 3.1–5.5 μm wide. Akinetes forming paraheterocytically, solitary or in pairs, elongated oval, with smooth, thin, colorless exospores, 10–25 μm long, 5.2–9.0 μm wide. Holotype: BRY37710, Monte L. Bean Museum, Provo, Utah. Paratype here designated BRY37713, Monte L. Bean Museum, Provo, Utah. Reference strain: CCALA 989, earlier also studied for its nitrogenase activity (Hrouzek et al. 2004, as strain 8C). Sequences: KF052605 and KF052606. Type locality: Soil, fallow field, Dlouhá Ves near Vodňany, Czech Republic. Sequence: KF052600. Secondary reference strain: CCALA 992 from cave sediment, Dlhá chodba in Domica system, Slovak Karst, Slovakia. Etymology: pellucidum = clear, referring to the colorless exospore. Enzalutamide manufacturer Taxonomic Org 27569 Notes: Differs from C. catenatum, C. licheniforme, C. moravicum, and C. badium by possession of colorless exospores. Also differs from these taxa in the secondary structure of the D1-D1′ helix. Cylindrospermum sp. CCALA 1002 (HA04236-MV2) from Hawaii (Fig. 7, a–k) Colony pale blue
green, spreading in thin layer on the surface of the substrate. Filaments pale blue-green, straight or slightly wavy, unsheathed, in thin diffluent mucilage. Trichomes motile, constricted at cross walls, 3.0–4.3 μm wide. Cells generally ungranulated, isodiametric to longer than wide, 2.5–7 μm long. End cells rounded or conical, elongated. Heterocytes terminal, intercalary only when two heterocytes occur in a row (preceding fragmentation?), round, oblong, or conical, mostly elongated, 4.3–5.7 μm wide, 4.9–8.9 (13.6) μm long, at one or both ends. Proakinetes elongated, with large angular or circular granules. Akinetes adjacent to heterocyte, single or in rows, ellipsoid, with smooth (light) brown exospore and granulated content, upon maturation 6–10 μm wide, 12–26.8 μm long. Reference strain CCALA 1002 (HA4236-MV02). Herbarium voucher BRY37723. Isolated from Moleka Stream (taro field), Makiki Valley by Hawaii Nature Center, Honolulu, Oahu, Hawaii.
