Type Information
Lectotype locality: Vosges, France.; (Drouet 1968: 174) Lectotype: CN; (Drouet 1968: 174) Notes: A "Holotype" an illustration in Gomont (1892, Ann. Sci. Nat. Bot. ser. 7, 16, plate 6, fig. 9") is given by Mühlsteinová et al. (2018:fig. 1 D); however, this can only be a lectotype (iconotype) and a lectotype was slected by Drouet (1968: 174, "type specimen, annotated by Kützing and studied by Gomont") in CN from Vosges in France. Epitype designated by Mühlsteinová & Guiry (2018:1): CBFS A-89-1, desiccated strain CCALA 1115 deposited in Herbarium of the University of South Bohemia, Ceské Budejovice, Czech Republic (CBFS).
General Environment
This is a freshwatermarinebrackish species.
Description
Trichomes blue-green, highly motile, not constricted at the cross-walls, narrowing toward the often bent ends, 24–36 ?m wide in the central area of the trichome and 14-27 (30) µm wide at the ends. Apical cells nearly hemispherical and often yellowish (together with up to five adjacent cells). Granulation never located at the cross-walls, but fine to larger granules randomly dispersed throughout cells. Cells 2-9 µm long, new cell walls form from the outside of the trichome often before the previous division is finished. Cell wall colourless and thick, necridic cells present, no sheath or calyptra observed (Mühlsteinová et al. 2018: 158).
Habitat
Blue-green mats first probably growing on the bottom of freshwater reservoirs, later often released and floating at the water surface.
