Arthrorhaphidaceae
The Arthrorhaphidaceae are a family of lichenized fungi in the division Ascomycota. This is a monotypic taxon, containing the single genus Arthrorhaphis, first described by Theodor Magnus Fries in 1860. The family was named by J. Poelt and J. Hafellner in 1976. Species in this family have a widespread distribution in temperate and montane habitats. They grow symbiotically with green algae, or parasitically on other lichens.
