Agaricus brunneofibrillosus

Agaricus brunneofibrillosus is a species of mushroom belonging to the genus Agaricus, within the family Agaricaceae. This species is part of the larger group of fungi known as basidiomycetes, which are characterized by producing spores on the surface of basidia. Agaricus brunneofibrillosus is notable for its distinctive physical characteristics and its ecological role in natural environments.

Description

Agaricus brunneofibrillosus features a cap that ranges from 5 to 10 cm in diameter, initially convex in shape, becoming more flattened as it matures. The cap surface is covered with fine, brown fibrils, giving the mushroom its name (brunneofibrillosus meaning "brown and fibrillose"). The gills are free from the stem, starting out pink in color and gradually turning chocolate brown as the spores mature. The stem is typically 4 to 8 cm in height, with a smooth surface and a ring. The flesh of the mushroom is white and does not change color upon cutting.

Habitat and Distribution

Agaricus brunneofibrillosus is primarily found in woodland areas, favoring environments rich in organic matter. It is a saprotrophic species, deriving nutrients from decomposing organic material, and plays a significant role in nutrient cycling within its ecosystem. The distribution of Agaricus brunneofibrillosus includes various temperate regions, although specific details on its geographic range are limited.

Edibility

The edibility of Agaricus brunneofibrillosus is not well-documented, and thus, it is recommended to exercise caution. Many species within the genus Agaricus are edible, but there are also species that contain toxins and can cause gastrointestinal distress. Proper identification by an experienced mycologist is essential before considering consumption.

Conservation

Information on the conservation status of Agaricus brunneofibrillosus is scarce. Like many fungi, its populations are influenced by factors such as habitat loss, pollution, and climate change. Efforts to document and understand its ecology are important for conservation planning.
