Collybia Clouds

Syzygospora mycetophila, commonly known as Collybia Clouds, is a fungal species belonging to the genus Syzygospora. This species is notable for being a mycoparasite, meaning it parasitizes other fungal fruiting bodies rather than obtaining nutrients from plant material or decaying organic matter directly. It has been documented across Europe and North America, with records from Denmark, Norway, and Sweden in Europe, and the United States in North America. The species typically grows on or near mushrooms of other species, particularly members of the former genus Collybia, forming distinctive white, cloud-like or granular growths on the host fruiting bodies. This unusual ecological strategy places it among a relatively small group of fungi that have evolved parasitic relationships with other fungi. Its conservation status has not been formally evaluated. Dietary behavior in the conventional sense is replaced by its parasitic nutrient acquisition from host fungi. Biological traits of this species remain poorly documented in the scientific literature. Syzygospora mycetophila is primarily encountered by mycologists surveying woodland habitats where its host fungi are abundant.

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。
