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.

Clavariadelphus helveticus is a club fungus in the family Gomphaceae, distinguished by its simple, unbranched fruiting bodies that emerge singly or in small clusters from forest soils. The genus Clavariadelphus comprises robust, fleshy, clavate fungi with smooth to slightly wrinkled surfaces, typically growing in association with coniferous or mixed forest trees through ectomycorrhizal relationships. Clavariadelphus helveticus in particular is associated with montane forests of central Europe, particularly the Alps and adjacent mountain ranges where it was first described. The fruiting bodies are generally pale buff to ochre or pinkish-buff, broadening toward the apex and tapering toward the base, reaching several centimeters in height. The flesh is firm and white, lacking the distinctive bitter taste of some related species. Spore dispersal occurs from the smooth to slightly roughened surface of the club. The species fruits in late summer to autumn, typically after periods of rainfall. Ectomycorrhizal club fungi contribute to forest nutrient cycling by facilitating mineral and water uptake in tree roots. Population dynamics of Clavariadelphus species are sensitive to forest management practices, soil disturbance, and climate-driven shifts in tree community composition. The conservation status of Clavariadelphus helveticus has not been formally assessed globally, though club fungi as a group are considered indicators of old-growth forest quality in European red-list assessments.
