Lyngbya majuscula, copyright David R.

Belongs within: Cyanobacteriia.

Lyngbya is a genus of filamentous blue-green algae in which trichomes are surrounded by a more or less thick, persistent sheath (Castenholz 2001).

Characters (from Castenholz 2001): Filamentous organisms producing a distinct, persistent, firm sheath. Sheath may be thin but can be seen with phase contrast optics, especially where extending beyond terminal cell of trichome; thick sheaths may accrete to several µm in diameter and display laminations. Trichome diameters ranging from about 6–80 µm; trichome cells disk-shaped, shorter than broad.
