Didymosphenia geminata, didymo or rock snot, is an invasive algal diatom found in lakes, streams and rivers. This freshwater
diatom produces thick algae mats along stream bottoms. The mats may be so thick that they can alter stream habitats and
make fishing difficult. Didyo can be spread easily from one water body to another. This microscopic algae, found in North
Carolina, now pose a threat to North Georgia streams and rivers. D. geminata occurs in locations with low phosphorus,
increased nitrogen, cooler water temperature (<10 C), neutral pH, low canopy cover, and moderate depth.
