Info
Lactarius acerrimus is a species of mushroom belonging to the family Russulaceae. This fungus is notable for its association with specific tree species and its distinctive features.
Taxonomy:
- Kingdom: Fungi
- Division: Basidiomycota
- Class: Agaricomycetes
- Order: Russulales
- Family: Russulaceae
- Genus: Lactarius
- Species: Lactarius acerrimus
Description:
Lactarius acerrimus can be identified by its unique morphological characteristics:
-
Cap: The cap typically measures between 5 to 15 cm in diameter and has a convex shape that may become more flattened with age. The surface is smooth and can be somewhat sticky when wet, exhibiting a color that ranges from pale yellow to ochre or reddish-brown.
-
Gills: This species possesses crowded, adnate to slightly decurrent gills that are closely spaced and can vary in color from pale yellow to light beige. The gills may have a slight staining tendency when bruised.
-
Stem: The stem is cylindrical and solid, measuring around 2 to 4 cm in thickness and can be up to 10 cm tall. Its color is typically lighter than that of the cap and can exhibit a slight fibrous texture.
-
Milk (Lactation): A defining characteristic of Lactarius species is their ability to exude a milky latex when cut or damaged. In the case of Lactarius acerrimus, the latex is often white and may have a slightly acrid taste, which is a key feature for identification.
Habitat and Distribution:
Lactarius acerrimus primarily forms mycorrhizal associations with certain tree species, particularly those in the family Aceraceae (maples), hence the name "acerrimus." It prefers deciduous forests and is typically found in leaf litter or under trees during the late summer to early autumn months. This species is distributed across temperate regions, with occurrences noted primarily in North America and parts of Europe.
Edibility:
Lactarius acerrimus is not widely regarded as an edible mushroom due to its acrid taste, which may cause gastrointestinal discomfort if consumed. Caution is advised for those interested in foraging, as several species in the Lactarius genus can be toxic or unpalatable.
Ecological Role:
As a mycorrhizal fungus, Lactarius acerrimus plays a significant role in forest ecosystems by enhancing nutrient uptake for host trees, particularly in forming symbiotic relationships with the roots. This symbiosis is vital for tree health and soil ecology, contributing to nutrient cycling and overall forest biodiversity.
Research and Uses:
While not extensively studied in terms of medicinal properties, Lactarius species are of interest in mycological research for their ecological roles and potential uses. Some Lactarius mushrooms are examined for their potential in bioremediation or as sources of natural compounds.
Conclusion:
Lactarius acerrimus is an interesting species within the diverse Lactarius genus, characterized by its unique features, ecological importance, and specific tree associations. As with many fungi, further research could uncover more about its role in ecosystems and potential applications. Foragers should exercise caution and ensure proper identification before considering any wild mushrooms for consumption.
