Anomalographis

About

Anomalographis is a genus of two species of lichen-forming fungi in the family Graphidaceae. These lichens form pale grey to yellow-brown crusts and are characterized by elongated, slit-like fruiting bodies containing very small spores divided by a single internal wall. One species grows on shaded volcanic rock faces in Madeira, while the other was discovered growing on tree bases in northeastern Queensland rainforest, showing the genus can colonize both rock and bark surfaces in humid, shaded environments.
