Megasporaceae

Megasporaceae are a family of fungi belonging to the order Pertusariales. Taxa are lichenized with green algae, and grow on rocks, often in maritime climates close to fresh water. Phylogenetic analysis has shown that this family is related to the Pertusariaceae, another family of lichens. The genus Aspicilia was moved here from the Hymeneliaceae.
