Description
Genus Igneoplaca is characterized by a crustose thallus, composed of red to orange lobes. Its cortical layer is paraplectenchymatous (fungal tissue with a cellular structure superficially like parenchyma of vascular plants), while its medulla is prosoplectenchymatous (fungal tissue with a structure superficially like collenchyma of vascular plants). Apothecia are lecanorine with a paraplectenchymatous true exciple. The lichen contains anthraquinones of the parietin chemosyndrome. Igneoplaca is similar to Calogaya, but that genus does not have a prosoplectenchymatous medulla.
Range & habitat
Igneoplaca ignea occurs in Baja Mexico and in southern California. It grows on rock in sunny areas, preferentially on acidic rock such as volcanic rock, schist, pebble, shale, and granite.
