Enclosed are a few images of what looks like a blue-green algae that
I scraped off the glass of a small (5-8 gal.?) aquarium. Referencing both
"FW Algae Flora of the British Isles" (DM John, et. al), and "Blue-Green
Algae of the British Isles-Interactive Key" (Lucid) (BA Whitton-NHBS), have
directed me to Pleurocapsa minor. However I'm puzzled by the lack of
pseudofilaments, perhaps these colonies are in their chroococcalean stage?
I don't remember encountering this organism during BG bloom analysis which
usually involves planktonic organisms, Microcystis, Anabaena etc. Any help
with this identification is appreciated...Thanks...Karl
