Caucasian Alder

The Caucasian Alder (Alnus subcordata) is a species in the genus Alnus. It is currently classified as Least Concern on the IUCN Red List. Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Hydropus trichoderma is a small, saprotrophic mushroom with a delicate, slender stipe and a pale, convex cap that grows on decaying woody debris in forest habitats. It is recorded from temperate European forests and contributes to wood decomposition in woodland ecosystems. Its Endangered status reflects rarity and the decline of undisturbed, mature forest with adequate deadwood.
