Russula nobilis
Russula nobilis, commonly known as the Beechwood Sickener, is a species of mushroom belonging to the genus Russula, which is part of the large family Russulaceae. This mushroom is notable for its striking appearance and its association with beech trees (Fagus spp.), from which its common name is derived. It is found primarily in Europe and parts of Asia, thriving in both deciduous and mixed woodlands.
Description[edit | edit source]
The cap of Russula nobilis can reach a diameter of 5 to 15 cm, starting with a convex shape before flattening out with age, often developing a central depression. The cap's color ranges from bright red to purple, with the intensity fading towards the margin. The gills are white to cream, attached to the stem, and can be quite crowded. The stem is white, robust, and measures 4 to 10 cm in height and 1 to 2.5 cm in diameter. This species does not have a ring or a volva.
The flesh of Russula nobilis is white and known for its acrid taste, which can be a distinguishing feature from other similar-looking species. The spore print is cream to pale yellow.
Habitat and Distribution[edit | edit source]
Russula nobilis is mycorrhizal, forming symbiotic relationships with beech trees, although it can also associate with other hardwoods. It is found in beech forests across Europe and Asia, preferring acidic to neutral soils. The fruiting season extends from late summer to autumn.
Edibility[edit | edit source]
Despite its attractive appearance, Russula nobilis is considered inedible due to its acrid taste and potential for causing gastrointestinal upset if consumed. Mushroom foragers are advised to exercise caution and avoid consumption of this species.
Similar Species[edit | edit source]
Russula nobilis can be confused with other red-capped members of the Russula genus, such as Russula emetica (the Sickener), which is also inedible. Careful attention to the taste, habitat, and association with specific tree species can aid in correct identification.
Conservation[edit | edit source]
Currently, there are no known significant threats to Russula nobilis, and it is not listed on any conservation red lists. However, maintaining healthy beech forests is crucial for the preservation of its habitat.
