Neoprotoparmelia capitata

Neoprotoparmelia capitata has a grey to greyish-brown, shiny and smooth to cracked crustose thallus. It often has a dark prothallus (visible as a line around the thallus margin). Soredia typically measure between 16 and 29 μm in diameter; they tend to clump together to form larger head-like ("capitate") soralia that are 0.8–1.25 mm in diameter, and 0.5–0.8 mm tall. Apothecia are rare, and pycnidia are not present. In its medulla, the lichen contains the secondary compounds alectoronic acid and traces of α-collatolic acid^[4]

Neoprotoparmelia capitata grows on the bark of hardwood trees in regions of the coastal plain of eastern North America. It tends to grows in subtropical areas, and at the time of its original publication, had been recorded from Alabama, Georgia, and Florida.^[2]
