Common corncockle

<em>Agrostemma githago</em>, commonly known as common corncockle, is an annual flowering plant in the family Caryophyllaceae. Once a widespread weed of cereal crops across Europe, Asia, and beyond, this species is now Critically Endangered on the IUCN Red List due to the dramatic decline caused by modern agricultural practices, particularly improved grain cleaning and herbicide use. Corncockle is a tall, slender plant covered in silky white hairs, bearing large, solitary pink to purple flowers with distinctive dark veining. Its seeds contain toxic saponin compounds called githagins, which historically contaminated grain supplies. The species now survives primarily in wildflower conservation areas, seed banks, and traditional farmland conservation schemes. It typically grows in open, disturbed arable soils with full sun exposure. Biological traits of this species remain poorly documented in the scientific literature.

Coprinopsis stercooreaは種名が示すように草食動物の糞と堆肥で豊かになった土壌に生育する小型インクキャップキノコである。ヨーロッパと北アメリカの温帯地域の牧場、馬小屋、糞堆積物がある森林に生息する。この糞生腐生菌類は糞の有機物を分解し、胞子が成熟すると傘を自己消化する。
