Lithothamnion is a genus of thalloid red alga comprising 103 species. Its members are known by a number of common names. The monomerous, crustose thalli are composed of a single system of filaments which grow close to the underlying surface. Lithothamnion reproduces by means of multiporate conceptacles.

Uses
The species Lithothamnium calcareum is, besides Tricalcium phosphate, often used as food fortification in plant-based milk substitutes to achieve a similar calcium content as a cow milk which is around 120 mg/100 ml. However, in April 2021 the European Court of Justice forbade its use in organic food products such as drinks.
Notes
- Recorded common names are griuán, maërl, punalevä-suku, stenhinna and maerl.
