Calopadia schomerae (Pilocarpaceae), a lichen from Everglades National Park.

A new lichen species, Calopadia schomerae, has been identified within Everglades National Park, distinguished by its unique morphological traits and adaptation to contrasting microhabitats. This discovery highlights the park's ecological diversity, as C. schomerae thrives in both shaded, high-humidity hammock forests (foliicolous) and drier, sun-exposed roadbeds (corticolous), exhibiting distinct pruinose apothecia characteristics depending on its environment. The species resembles Calopadia fusca and C. lucida, but notable differences in structure set it apart. The study, based on voucher specimens from these diverse substrates, underscores the importance of microhabitat-specific adaptations in lichen taxonomy.
