Alder leaf beetle

The Alder leaf beetle (Agelastica alni) is a species in the genus Agelastica. It is currently classified as Least Concern on the IUCN Red List. Typically found in virtually all terrestrial and freshwater habitats.

Clitocybe subalutacea is a pale, leather-colored agaric fungus in the family Tricholomataceae found across temperate European woodlands and semi-open habitats. The species epithet subalutacea derives from Latin for 'somewhat leather-colored,' referencing the cap's pale tan to buff coloration distinguishing it from more purely white or grey species in the genus. It fruits in autumn among leaf litter in deciduous and mixed forests, occasionally in grassy woodland clearings, acting as a saprotrophic decomposer of accumulated organic matter. The fruiting body structure is characteristic of Clitocybe: a shallowly depressed to funnel-shaped cap, crowded decurrent gills, and a slender cylindrical stipe. Microscopic spore morphology and chemical reactions assist in confirming identity in this taxonomically complex genus. Like most Clitocybe species, C. subalutacea contributes to decomposer communities in temperate forests, where the collective activity of many fungal species drives litter breakdown and nutrient release, underpinning forest productivity and soil health across European woodland ecosystems.
