Haloplaca suaedae

About

Haloplaca suaedae is a species of epiphytic (plant-dwelling), crustose lichen in the family Teloschistaceae. It grows exclusively as an epiphyte on shrubby sea-blite. First described in 2001 as Caloplaca suaedae, it was later reclassified in the genus Haloplaca. The lichen is characterised by its extensive grey-green to pale grey thallus composed of small, warty segments, and numerous small orange apothecia with distinctive yellow rims. Found primarily in coastal salt marsh environments and around saline lagoons, it has been documented in England, Greece, Morocco, and Turkey, where it is adaptated to periodic salt water inundation.
