A ave nacional dos Estados Unidos e símbolo do sucesso conservacionista americano, a águia-careca tem uma envergadura de até 2,4 metros e habita florestas e zonas húmidas próximas de águas abertas em toda a América do Norte. Quase extinta na década de 1960 devido ao envenenamento por DDT e à caça, recuperou de forma notável após as proibições de pesticidas e a Lei das Espécies em Perigo.

Ciboria betulicola is a small cup fungus in the family Sclerotiniaceae, found in temperate Europe. Like its close relative Ciboria betulae, this species is associated with birch (Betula) and fruits on fallen catkins or other birch reproductive material in moist woodland and riparian habitats. Its fruiting bodies are stalked discomycetes with the characteristic pale to brownish cup shape of the genus, typically emerging in late spring or early summer following catkin fall. The species has not been formally assessed by the IUCN. Ciboria betulicola is distinguished from the closely related Ciboria betulae and other congeners by a combination of spore morphology, ascocarp dimensions, and substrate details, with microscopic examination required for confident identification. Saprotrophic cup fungi of this type play important ecological roles in decomposing the fine organic material of woodland floors and riparian zones, facilitating nutrient return to the soil. Records of Ciboria betulicola are relatively sparse in the mycological literature, reflecting both its small size, brief fruiting season, and the general under-recording of discomycetes compared to larger macrofungi. Its distribution is thought to track birch woodland distribution across northern and central Europe, though documentation is incomplete. Molecular phylogenetic studies have helped clarify relationships within Ciboria and Sclerotiniaceae more broadly.
