Harmful effect A strain of this benthic species was isolated from a drinking water reservoir in Pernambuco State, Brazil and found to produce the saxitoxin variant GTX1 (Borges et al. 2015). Cells were identified by both morphological and molecular methods [details]

Description Thallus dark green to brownish black, widely expanded, adherent, thin, firm or floating and (sometimes) fasciculate, attached by the base, thick. Filaments straight or slightly bent. Sheaths mucilaginous, firm or diffluent. Trichomes blue-green or dirty green, (4) 5.5-9 (9.5) μm wide, not constricted at the often granulated cross-walls, briefly attenuated at the ends and hooked or feebly coiled, rapidly motile, with anticlockwise rotation and strong oscillation. Cells 1/2-1/3x as long as wide, rarely up to subquadrate, 2-6 μm long. Apical cells capitate, mostly with obtuse, rarely rounded-conical calyptra.
