Dr. Paul Gainey investigated this species further, collected material and found that the species was almost certainly Rivularia biasolettiana because of the presence of very small calcite crystals between the filaments.

The species here still needs to be verified by an expert in the field of cyanobacteria.

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help

people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
