Description Trichomes mostly solitary, free-floating, up to 300 μm long, straight or somewhat curved, sometimes joined to blue-green or olive-green, microscopic, loose fascicles, occasionally forming benthic membranaceous coat (thallus), without sheaths, or very rarely and facultatively, especially in young stages, with fine sheaths. Trichomes (2.3) 4 - 6 (9.8) μm wide, immotile, not constricted (or very slightly constricted) at the granulated cross-walls, ± gradually attenuated at the ends. Cells shorter than wide or frequently isodiametric, up to 2x longer than wide (before division); cell content blue-green, with numerous aerotopes, without PE. Apical cells convex, sometimes bluntly-conical or ± pointed, sometimes with convex calyptra, rarely capitate. [details]

Distribution Freshwater, planktic in lakes and ponds, often forming water blooms, widely distributed in temperate zones; Europe: Austria, Czech Republic, Den¬mark, Finland, France, Germany, Hungary, Netherlands, Norway, Poland, Russia, Slovakia, Spain, etc.; less recorded from tropical regions (revision of the genotype identity is necessary). Data from non-planktic biotopes (cells without gas vesicles) belong surely to other species (e.g., Hirano 1962).

Description Trichomes mostly solitary, free-floating, up to 300 μm long, straight or somewhat curved, sometimes joined to blue-green or olive-green, microscopic, loose fascicles, occasionally forming benthic membranaceous coat (thallus), without sheaths, or very rarely and facultatively, especially in young stages, with fine sheaths.

Distribution Freshwater, planktic in lakes and ponds, often forming water blooms, widely distributed in temperate zones; Europe: Austria, Czech Republic, Den¬mark, Finland, France, Germany, Hungary, Netherlands, Norway, Poland, Russia, Slovakia, Spain, etc.; less recorded from tropical regions (revision of the genotype identity is necessary). Data from non-planktic biotopes (cells without gas vesicles) belong surely to other species (e.g., Hirano 1962).
