Bob Baldock reports on algae found in the Botanic Gardens recycle-ponds: this time on a spiral blue-green alga that entwines a green alga!
Leibleinia epiphytica (arrowed in photograph) is a cosmopolitan, extremely thin, thread-like photosynthetic bacterium (Cyanophyte, or blue-green alga) that wraps itself around threads of other algae. Here it has embraced the common green alga, Oedogonium. Both were found in the small rafts of algae floating in recycle ponds.
Amazing what you find under the microscope!
