Description
Strictly speaking this is algae and blue-green bacteria, not a fungus. On glass it is only cosmetic, but slimy blue-green to black sheets can smother moss. Shorter days, less light, distilled water, no fertiliser and a few snails keep it down.
Also called green glass film, blue-green slime, black beard film.
