Anthracothecium is a genus of lichen-forming fungi in the family Pyrenulaceae. It comprises five species of crustose, bark-dwelling, lichens in the tropics and subtropics, and that in the current sense the genus is diagnosed by young ascospores that are euseptate (true septa) and remain mostly euseptate when mature, contrasting with Pyrenula, where and thickened is the norm. The ascomata (fruiting bodies) are (blackened and charcoal-like), usually simple or aggregated in predictable ways, and ostioles may be apical or lateral depending on species.
