American Bald Eagle

The national bird of the United States and a symbol of American conservation success, bald eagles have a wingspan of up to 2.4 meters and inhabit forests and wetlands near open water across North America. Powerful aerial predators and scavengers, they specialize in fish but also take waterfowl and carrion. Nearly extinct by the 1960s due to DDT poisoning and hunting, the bald eagle recovered dramatically following pesticide bans and the Endangered Species Act.

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.
