Clitocybe diatreta is a saprotrophic agaric fungus belonging to the family Tricholomataceae, found across temperate European forests and woodland habitats from Scandinavia southward through Central Europe. It typically fruits in autumn among leaf litter of deciduous and mixed forests, favoring moist, humus-rich soils beneath beech, oak, and conifer stands. The cap is convex to depressed, pale greyish-buff or whitish, with the decurrent gills and funnel-shaped profile characteristic of the genus Clitocybe. Microscopic examination reveals ellipsoid spores with smooth walls, confirming identity in this difficult taxonomic group. The diatreta species complex has been subject to taxonomic revision as molecular techniques clarify boundaries between morphologically similar taxa. As a decomposer of forest litter, C. diatreta contributes to the breakdown of cellulose and lignin in temperate forest floors, releasing nutrients back into the soil ecosystem. Its presence indicates structurally diverse, undisturbed forest conditions preferred by many specialist saprotrophic fungi in European woodland communities.

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。
