    Cyanomargarita gen. nov. (Nostocales, Cyanobacteria): convergent evolution resulting in a cryptic genus

    Line drawings of Cyanomargarita melechinii from natural populations. (A) Underwater colonies on stones and mosses. (B) Spherical macrocolonies on moss leaf. (C and D) Filaments forming tufts within colony. (E) Single filaments with false branching, firm sheath, and constrictions at crosswalls. (F) Variably shaped heterocytes. Numerals indicate diagnostic characteristics used in species description: 1, Filament without constrictions; 2, sheath with wavy striations; 3, funnel-like widened sheaths; 4, two heterocytes in the row; 5, intercalary involution cells; 6, juvenile single trichome without individual sheath; 7, geminate branching on juvenile single trichome; 8, two necridia in a row; 9, different shaped heterocytes; 10, thin apical hairs.

    Laurencia pumila var. dehoopiensis var. nov.: (A) Habit. (B) Polystichous branching pattern (scale bar = 360 μm). (C) Pericentral (p) and axial (a) cells (scale bar = 100 μm). (D) Outermost cortical and innermost cortical cells (scale bar = 50 μm). (E) A single corps en cerise per cell (scale bar = 30 μm).

    Two new species in the Chaetoceros socialis complex (Bacillariophyta): C. sporotruncatus and C. dichatoensis, and characterization of its relatives, C. radicans and C. cinctus

    Chaetoceros dichatoensis sp. nov., spores. (A–J) strain Ch4A4. (A) LM and (B–J) SEM. (A) A chain of cells, many of which contain spores. (B–E) Spores; note the variability of spine size, shape and density. (F) Opened spore. (G) View of the secondary valve in which almost exclusively ridges are present. (H) Valve in which both spines and ridges are present. (I, J) Secondary valves with the ring of puncta arrowed. Scale bars: (A) = 10 μm, (B–J) = 1 μm.

  • Morphological and molecular characterization of Bysmatrum subsalsum (Dinophyceae) from the western Mediterranean Sea reveals the existence of cryptic species

    Morphological and molecular characterization of Bysmatrum subsalsum (Dinophyceae) from the western Mediterranean Sea reveals the existence of cryptic species

    Scanning electron and light micrographs show the deviation from the typical plate pattern of Bysmatrum subsalum cells from the Western Mediterranean Sea. (A) The 1a plate contacting the 1′ plate and (B) the 1a plate not directly contacting the 1″ plate are seen. Scale bars represent 10 μm.
