橄榄灰鹅膏菌（Amanita olivaceogrisea）是鹅膏科中的一种外生菌根真菌，以橄榄灰色的菌盖颜色为其命名依据，与多种阔叶树和针叶树形成共生菌根关系。该物种与其所在生态系统的树木健康密切相关，通过地下菌丝网络促进宿主植物的水分和矿质营养吸收。鉴于鹅膏属中毒蕈普遍，切勿轻易采食野生鹅膏。

koala

澳大利亚东部和东南部的标志性有袋类动物，体重最大可达15千克，为了节省低热量桉树叶食物所提供的能量，每天最多睡眠22小时。高度特化，能够处理会致大多数其他哺乳动物死亡的有毒桉树成分，拥有专门适应解毒功能的肠道微生物群。因衣原体病、栖息地开发和气候变化导致种群锐减，2022年被列为濒危物种。
