Cockroach berry

The cockroach berry (Solanum capsicoides) is a spiny, semi-woody shrub in the family Solanaceae — the nightshade family — native to eastern Brazil but now established as an invasive or naturalised weed throughout the humid tropics, including parts of Africa, Asia, Australia, and the Pacific islands. Growing to about one metre in height, it is armed with sharp, straight prickles on stems, leaves, and even the calyx, making it unpalatable to grazing animals and difficult to control mechanically. The leaves are lobed and pubescent, resembling those of other weedy solanums, and the plant produces clusters of small white flowers with yellow anthers characteristic of the genus. The globose fruits, around two to three centimetres in diameter, are initially green with white marbling and ripen to orange or red; they superficially resemble small chilli peppers or tomatoes but are toxic to humans and most livestock, containing solanine and related steroidal alkaloids. Birds are primary dispersers of the seeds, facilitating the plant's rapid spread in disturbed habitats including roadsides, forest margins, degraded pastures, and abandoned agricultural land. Solanum capsicoides is Not Evaluated on the IUCN Red List, reflecting its status as a common, widespread, and spreading species rather than one of conservation concern. In its invasive range it can form dense monospecific thickets that suppress native vegetation.

Common Fieldcap

The Common Fieldcap (<em>Agrocybe pediades</em>) is a saprotrophic fungus belonging to the genus Agrocybe within the family Strophariaceae. It typically produces small, tan to pale brown cap-shaped fruiting bodies and is often found growing in clusters or scattered on lawns, grassy areas, forest floors, decomposing wood, and soil-rich ecosystems. The species typically inhabits forest floors, decomposing wood, and soil ecosystems, obtaining nutrients by breaking down dead organic matter. Its geographic range includes several European countries — Belgium, Denmark, Norway, Portugal, and Sweden — as well as the United States in North America. <em>Agrocybe pediades</em> is assessed as Least Concern on the IUCN Red List, reflecting its broad distribution and apparent stability. Biological traits of this species, including specific data on fruiting body size, lifespan, and ecological preferences, remain poorly documented in the scientific literature. Like other members of its genus, it typically fruits during warmer months and often appears after rainfall in nutrient-rich grassland and woodland habitats.
