Cortinarius camphoratus, commonly known as the Girdled Webcap, is a species of mushroom belonging to the large genus Cortinarius within the family Cortinariaceae. This mushroom is notable for its distinctive camphor-like smell, from which its name is derived. It is found in various parts of the world, primarily in temperate forests, where it forms mycorrhizal associations with a wide range of trees. This symbiotic relationship is crucial for the nutrient exchange between the soil and the trees, playing a vital role in forest ecosystems.

Description

Cortinarius camphoratus features a cap that ranges from 4 to 10 cm in diameter, initially convex before flattening out with age, often with a slight umbo at the center. The cap's color can vary from brown to reddish-brown, with a slightly paler margin. The gills are adnate to emarginate, crowded, and initially pale before turning a rusty brown as the spores mature. The stipe (stem) is 4 to 8 cm long and 1 to 2 cm thick, cylindrical, and bears the same color as the cap but may lighten towards the base. A distinctive feature of this species is the presence of a cortina (a web-like veil) in young specimens, which disintegrates as the mushroom matures, leaving behind a ring zone on the stipe.

The spore print of Cortinarius camphoratus is rusty brown, typical of the Cortinarius genus. Its spores are broadly ellipsoid, smooth, and possess a dextrinoid reaction when stained with Melzer's reagent.

Habitat and Distribution

Cortinarius camphoratus is predominantly found in temperate forests across North America, Europe, and Asia. It forms ectomycorrhizal relationships with a variety of trees, including both deciduous and coniferous species. This mushroom prefers moist, well-drained soils rich in organic matter and is typically found growing in small groups.

Edibility

The edibility of Cortinarius camphoratus is questionable. While not considered toxic, its strong camphor-like odor may be off-putting to some, and it is not generally regarded as a choice edible mushroom. As with all wild mushrooms, caution is advised when identifying and consuming them, due to the risk of confusion with potentially toxic species.

Conservation

As of now, Cortinarius camphoratus does not appear to be under any immediate threat. However, like many fungi, it could be susceptible to changes in its habitat, such as deforestation, pollution, and climate change. Conservation of its natural habitat is essential for the preservation of this species.
