Tetramelas is a genus of lichen-forming fungi in the family Caliciaceae. The genus is distinguished by its distinctive spores, which are divided into four compartments and turn brown as they mature, giving rise to the name Tetramelas from the Greek words for 'four' and 'dark'. These lichens typically form greyish crusts on rocks, bark, or other surfaces, with small black disc-shaped fruiting bodies that contain the characteristic four-chambered spores.
