The "generic" name in the requirement means that you should learn which genus ten specimens belong to. Don't be scared of the scientific names (Latin names) - they are no more difficult to learn than the common names, especially if you know neither when you start.<br>
We present several species below, but you should not expect that these are the only samples you will find. Get a good field guide and identify the algae you ''find'' rather than trying to find the algae you can identify.
