Lithothamnion is a genus of thalloid red alga comprising 103 species. Its members are known by a number of common names, such as griuán, maërl, punalevä-suku, stenhinna, and maerl^{[what language is this?]}.^{[citation needed]} 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.

Species

The valid species currently considered to belong to this genus are:

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.^[2] However, in April 2021 the European Court of Justice forbade its use in organic food products such as drinks.^[3]^[4]^[5]^[6]^{[needs update?]}
