: These look like hair-like strands or tangled mats. Spirogyra often feels slick and slimy. Pithophora feels "cottony" and coarse.
Color provides a major clue about the pigments the algae uses for photosynthesis: Chara (skunkweed) grows from the bottom and often
First, look at how the algae is structured in the water. Most common types fall into these three categories:
: Diatoms often feel gritty (like sand) because of their glass-like silica shells. Identification Resources If it is slimy and slips off immediately,
: Fresh blooms often smell like freshly mowed grass; older, decaying blooms may smell like rotting garbage.
