Clitocybe subcordispora is a saprotrophic agaric fungus in the family Tricholomataceae, with the species epithet subcordispora likely referencing slightly heart-shaped or cordiform spores observed under microscopy, a feature useful in distinguishing it from other pale Clitocybe species. It inhabits temperate European forest floors, woodland margins, and grassy clearings, fruiting in autumn among leaf litter and humus. The fruiting body presents the characteristic Clitocybe form with a depressed to funnel-shaped pale cap, decurrent gills, and cylindrical stipe. Spore morphology is an important taxonomic character within this genus, and the slightly cordiform spore outline of C. subcordispora may reflect adaptation to specific dispersal modes or represent a plesiomorphic character within the clade. The species contributes to saprotrophic fungal diversity in European temperate forests, where dozens of Clitocybe species occupy slightly different ecological niches in the decomposition of leaf litter, woody debris, and soil organic matter, collectively driving the nutrient cycling processes essential to forest ecosystem function.

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。
