Antidea

Antidea is a fungal genus in the family Megasporaceae (order Pertusariales). It comprises the single species Antidea brucei, a crustose lichen that forms small gray patches of tightly packed tiles on siliceous rocks. The species was originally described as Aspicilia brucei in 2007 from California, but DNA studies showed it represented an early-diverging lineage within Megasporaceae, leading to its placement in a new genus in 2024. Known primarily from mid-elevation forested sites in southwestern North America, the species has also been reported from parts of Europe....read more on Wikipedia.
