Laysan Duck

Laysan Duck (Anas laysanensis) is classified as Critically Endangered (CR) on the IUCN Red List. Facing an extremely high risk of extinction in the wild due to severe population decline and habitat loss.

Postia lowei is a soft, white to cream-colored bracket fungus forming annual, shelf-like fruiting bodies on decaying conifer wood. It inhabits boreal and montane coniferous forests, growing on dead fallen logs and stumps. This brown-rot saprotrophic fungus decomposes the cellulose of conifer wood, leaving characteristic brown cubical rot.
