地球上で生きたことが知られている最大の動物であるシロナガスクジラ（Balaenoptera musculus）は、体長33メートル、体重200トンに達することができ、心臓だけで小型自動車ほどの重さがあります。全ての海洋に生息し、極地の餌場と熱帯の繁殖地の間を回遊します。1日最大4トンのオキアミを摂取する濾過摂食者です。20世紀の捕鯨による絶滅危機からの回復後、世界的な個体数は10,000〜25,000頭と推定される絶滅危惧種です。

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.
