Clitocybe foetens is a notably malodorous agaric fungus in the family Tricholomataceae, with the species epithet foetens Latin for 'stinking' or 'fetid,' reflecting its distinctive unpleasant odor that sets it apart from many related species. It occurs across temperate European forests, particularly in deciduous and mixed woodlands, where it fruits among leaf litter and organic debris during autumn. The cap is convex to shallowly depressed, pale brownish to greyish-buff, with decurrent gills and a slender stipe bearing the characteristic Clitocybe morphology. The strong, disagreeable smell is likely produced by volatile compounds and serves as a chemical signal, though whether it deters or attracts invertebrates and other fauna varies by compound chemistry. Like other genus members, C. foetens is a saprotrophic decomposer contributing to litter breakdown in temperate forest ecosystems. The fetid odor also serves as a useful distinguishing character for mycologists working in this taxonomically complex genus of small, pale-capped agarics found throughout European woodland habitats.

koala

オーストラリア東部・南東部を代表する有袋類で、体重は最大15kgに達し、低カロリーのユーカリの葉食から得るエネルギーを節約するために1日最大22時間を睡眠に費やす。他の哺乳類の多くを死に至らしめる有毒なユーカリ成分を処理するために高度に特化しており、解毒に特別に適応した腸内微生物叢を持つ。クラミジア感染症、生息地の伐採、気候変動により個体数が激減し、2022年に絶滅危惧種に指定された。
