# Takmos

Takmos (Ramalina) is een geslacht van struikvormige korstmossen dat behoort tot de orde Lecanorales van de ascomyceten. De typesoort is het groot takmos (Ramalina fraxinea). Het geslacht omvat ruim 100 soorten.
Takmossen produceren usninezuur. Men neemt aan dat het de korstmossen tegen ultraviolette straling beschermt en door zijn intens bittere smaak korstmossen beschermt tegen begrazing.
