Definition
Caloplaca obamae is a species of crustose lichen in the family Teloschistaceae. It is recognized as a distinct taxon within the genus Caloplaca.
Overview
The species was formally described in the scientific literature in the early 21st century. It is known from a limited geographic range, primarily occurring on exposed rock substrates in certain regions of the Hawaiian Islands. The lichen forms thin, brightly colored patches that contribute to the biodiversity of the local lichen flora. The naming of the species honors former United States President Barack Obama, acknowledging his environmental policies and support for conservation efforts.
Etymology/Origin
The generic name Caloplaca derives from Greek roots meaning “beautiful plate,” referring to the often vivid, plate‑like apothecia of many species in the genus. The specific epithet obamae is a patronymic Latinized form honoring Barack Obama. The combination thus denotes “the beautiful plate lichen named after Obama.”
Characteristics
- Thallus: Thin, crustose, typically orange‑to‑yellowish, adhering tightly to rock surfaces.
- Apothecia: Frequently present; disc-shaped, often vividly pigmented, aiding in spore dispersal.
- Photobiont: Contains a green algal partner (commonly a Trebouxia spp.).
- Habitat: Primarily saxicolous (rock‑dwelling) in coastal or montane settings with moderate sunlight exposure.
- Distribution: Documented from a few localities within the Hawaiian archipelago; broader distribution beyond these sites has not been confirmed.
