Aulne maritime

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

Common Cavalier

<em>Melanoleuca polioleuca</em>, commonly known as the common cavalier, is a fungal species with documented occurrences in Belgium, Norway, and Sweden. It typically inhabits forest floors, decomposing wood, and soil, often emerging in temperate woodland environments where organic matter is abundant. The species is classified as Least Concern on the IUCN Red List, indicating that it is not currently facing significant conservation threats at a global level. Common cavalier belongs to the genus <em>Melanoleuca</em> within the family Tricholomataceae. It is a saprotrophic mushroom that typically produces medium-sized fruiting bodies with pale or grayish caps and white gills, often found growing singly or in small groups in deciduous and mixed forests. As a decomposer, the species plays an important role in nutrient cycling within its ecosystem. Biological traits such as average lifespan, cap diameter, and biomass of this species remain poorly documented in the scientific literature. Its distribution across northern Europe suggests adaptation to cool temperate woodland conditions.
