Agaricus langei, commonly known as Lange's mushroom, is a species of fungus belonging to the genus Agaricus, within the family Agaricaceae. This species is part of the larger group of mushrooms commonly referred to as the field mushrooms or meadow mushrooms, which are widely appreciated for their edible qualities. The specific epithet langei honors the mycologist Jakob Emanuel Lange, who made significant contributions to the study of Agaricus species.

Description

Agaricus langei features a cap that can range from 5 to 10 cm in diameter, initially spherical before flattening out with age. The cap surface is typically white to light brown, with a smooth texture that can become cracked in dry conditions. The gills are free from the stem, densely packed, and progress from pink to a dark chocolate brown as the mushroom matures, a characteristic trait of many Agaricus species. The stem is 3 to 6 cm tall, with a bulbous base and a ring that remains as a remnant of the partial veil that once enclosed the immature gills.

Habitat and Distribution

This mushroom is found in grasslands, fields, and meadows, often forming rings or arcs known as "fairy rings," due to the radial growth pattern of the mycelium in the soil. Agaricus langei has a preference for calcareous soils and is more commonly found in Europe, although it has been reported in various parts of North America and other regions where conditions are suitable.

Edibility

Agaricus langei is considered edible, with a taste and aroma that are mild and pleasant, typical of many members of the Agaricus genus. However, as with all wild mushrooms, caution is advised when foraging, as it can be confused with other less palatable or even poisonous species. Proper identification by an experienced mycologist is recommended before consumption.

Conservation

While not currently listed as endangered or under significant threat, the habitat of Agaricus langei is susceptible to the impacts of agricultural and urban development. Conservation of grassland habitats is essential for the preservation of this species and the broader biodiversity of meadow ecosystems.
