Paraschismatomma

Paraschismatomma is a fungal genus in the family Opegraphaceae. It comprises a single species, Paraschismatomma ochroleucum, a crustose lichen found along the western coast of North America from northern California to Baja California. The lichen grows as a thin, greenish-white crust on dead twigs, branches, and tree bark near the ocean. First described by the lichenologist Alexander Zahlbruckner in 1900, P. ochroleucum has undergone several name changes before being classified in its own genus in 2011.
