Alpine Rock-Cress

The Alpine Rock-Cress (Arabis alpina) is a species in the genus Arabis. It is currently classified as Least Concern on the IUCN Red List. Typically found in diverse terrestrial habitats from tropical forests to temperate regions. Widely distributed across Europe (10 countries), North America (Canada, United States), and South America (Argentina).

Clitocybe subspadicea is an agaric fungus in the family Tricholomataceae native to temperate European forests. The species epithet subspadicea indicates a date-brown or chestnut-brown coloration ('spadiceus' meaning date-brown in Latin), somewhat darker than the whitish or pale grey tones typical of many Clitocybe species, making it more readily distinguished in the field. It fruits in autumn on forest floors of deciduous and mixed woodlands, where it decomposes leaf litter and organic matter as a saprotrophic fungus. The cap is depressed to funnel-shaped, gills are decurrent and crowded, and the stipe is cylindrical and slender, following the typical Clitocybe growth form. The darker pigmentation may reflect production of melanins or other pigment compounds providing protection against UV radiation or desiccation during fruiting. Documentation of species like C. subspadicea through careful field work and herbarium specimens contributes to understanding the remarkable macrofungal diversity of European temperate forests, where hundreds of agaric species perform essential ecological roles in energy flow and nutrient cycling.
