Common Fieldcap

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Found across Europe (5 countries) and North America (United States).

メンフクロウ

メンフクロウ（Tyto alba）は、南極大陸を除くすべての大陸に生息する世界で最も広く分布するフクロウの一種で、熱帯雨林から温帯農地まであらゆる生息地タイプで見られます。ハート型の顔盤が音を左右非対称に配置された耳に集め、完全な暗闇の中でも音だけで獲物を捉えることができます。獲物を丸呑みにし、消化できない骨と毛を圧縮したペレットとして吐き出すため、農業においてネズミ類の防除に役立つ存在です。

Common Fieldcap

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.
