Coleroa robertiani is an ascomycete fungus in the family Phacidiaceae, specialized as a parasite or saprotrophic organism on herb-Robert (Geranium robertianum) and related geraniums (family Geraniaceae). The species produces small, dark apothecia on senescent or infected leaf tissue, releasing ascospores that perpetuate the fungal life cycle. Like other Coleroa species, it forms characteristic setose (bristle-bearing) fruiting bodies that anchor to host plant surfaces. This fungus is recorded primarily from temperate European regions where Geranium robertianum grows in shaded, moist habitats such as hedgerows, woodland edges, and rocky slopes. Its host specificity to Geraniaceae reflects co-evolutionary relationships between fungal lineages and particular plant families. Coleroa robertiani is generally not considered an economically significant pathogen given the weed or naturalized status of its host plants in many areas, but it plays a role in regulating wild Geranium populations and cycling nutrients through decomposition of infected tissue. As with many microfungi on minor hosts, detailed ecological and distributional data are sparse, and molecular phylogenetic studies continue to refine its classification within the broader Rhytismatales.

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。
