Halbkugeliger Ackerling

The Common Fieldcap (<em>Agrocybe pediades</em>) is a saprotrophic fungus belonging to the genus Agrocybe within the family Strophariaceae. It typically produces small, tan to pale brown cap-shaped fruiting bodies and is often found growing in clusters or scattered on lawns, grassy areas, forest floors, decomposing wood, and soil-rich ecosystems. The species typically inhabits forest floors, decomposing wood, and soil ecosystems, obtaining nutrients by breaking down dead organic matter. Its geographic range includes several European countries — Belgium, Denmark, Norway, Portugal, and Sweden — as well as the United States in North America. <em>Agrocybe pediades</em> is assessed as Least Concern on the IUCN Red List, reflecting its broad distribution and apparent stability. Biological traits of this species, including specific data on fruiting body size, lifespan, and ecological preferences, remain poorly documented in the scientific literature. Like other members of its genus, it typically fruits during warmer months and often appears after rainfall in nutrient-rich grassland and woodland habitats.

Zimtblättriger Birken-Wasserkopf

Cortinarius subbalaustinus is a medium-sized, web-capped mushroom with rusty-brown coloring and a cortina veil characteristic of the large Cortinarius genus. It grows in deciduous and mixed forests forming ectomycorrhizal associations with oak and related hardwood trees in temperate Europe. This fungus exchanges nutrients with tree roots and produces fruiting bodies in autumn.
