Description: |
In general, the blue-green algae (Cyanobacteria) are not easy to find on the coastline. However, a species can be easily confused with a green alga, so we describe here: This species forms small globular vesicles, dark-green, sometimes bluish, gelatinous and elastic, adherent to exposed rocks, sometimes on Chthamalus spp. (barnacles), together with Lichina pygmaea (lichens), and may reach 5 mm in diameter (Pereira, 2009).
