Named for their tendency to become encrusted with calcium carbonate, stoneworts are a type of freshwater green algae in the taxonomic order Charales. They are particularly hardy organisms in low to medium nutrient-rich water, but often die in water that is insufficiently oxygenated.
- In real life, Stonewort is the common name for Charales, which is not a phylum, but an order, two levels beneath.
