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 viridifusca is a saprotrophic discomycete in the family Sclerotiniaceae, found in temperate Europe. It produces small, stalked cup-shaped fruiting bodies with an olive-brown to greenish-brown (viridifusca: green-brown) coloration, which distinguishes it from other members of the genus with more uniformly tan or chestnut coloration. The species fruits on fallen catkins or other plant debris in moist deciduous woodland, typically in spring or early summer following the fall of host plant material. It is classified as Least Concern, indicating stable populations within its European range. Ciboria viridifusca contributes to saprotrophic communities in woodland ecosystems, decomposing fine organic litter and participating in the cycling of carbon and nutrients. Like other Ciboria species, it is a specialist saprotroph closely tied to the availability of suitable host plant substrates. Identification requires microscopic examination, and this species may be confused with related taxa without careful analysis of spore dimensions and color. The genus Ciboria is part of the broader Sclerotiniaceae family, which is well-studied owing to its inclusion of economically important plant pathogens, though the Ciboria species themselves are benign decomposers. Records of this fungus are scattered across central Europe, and accurate distribution mapping requires systematic mycological surveys. Conservation of mature deciduous woodland benefits discomycete diversity broadly.
