Nostoc commune - Nostoc commune

Description

This is a cyanobacteria, one of the so called 'blue-green algae'.  You can usually see them when they’re concentrated into brownish or greenish clumps, often appearing as a scum, but which can sometimes look quite 'plant like'.

Habitat

In fresh waters they can be found suspended within the water, but are often attached to rocks and other damp surfaces where they form large clumps.

When to see it

Water born algae are normally encountered in the hot summer months, but clumps of algae in damp areas can be seen in most months of the year.
