The Oyster mushroom, or Pleurotus ostreatus, is a common edible mushroom. It was first cultivated in Germany as a subsistence measure during World War I and is now grown commercially around the world for food. Oyster mushrooms can also be used industrially for mycoremediation purposes. The Oyster mushroom may be considered a medicinal mushroom since it contains statins such as lovastatin which work to reduce cholesterol. The mushroom has a broad, fan or oyster-shaped cap spanning 5–25 cm; natural specimens range from white to gray or tan to dark-brown; the margin is inrolled when young, and is smooth and often somewhat lobed or wavy. The flesh is white, firm, and varies in thickness due to stipe arrangement. The gills of the mushroom are white to cream, and descend on the stalk if present. If so, the stipe is off-center with a lateral attachment to wood. The spore print of the mushroom is white to lilac-gray, and best viewed on dark background. The mushroom's stipe is often absent. When present, it is short and thick.

The Common Garden Slug is a widespread species throughout Britain and also found in Europe and North America. This slug is typically found in habitats with a strong human influence such as gardens and parks. It breeds throughout much of the year and can be a serious pest of gardens as they attack cultivated plants, fruit, tubers and bulbs, which are eaten by means of a rasping tongue known as a radula. They emerge at night, and spend the day in moist places beneath stones, logs and other objects. Slugs are related to snails; in the genus Arion, the shell is reduced to a group of calcareous granules below the 'mantle', which appears as a bulge on the upper surface of the slug.Slugs are hermaphrodites, meaning that individuals possess both male and female reproductive organs, but self-fertilisation does not occur. During courtship, members of a pair follow each other in circles, whilst feeding on their partner's mucus trail.
