The order Russulales is a diverse group of basidiomycete fungi, primarily known for their ecological roles as ectomycorrhizal partners with trees, aiding in nutrient exchange, as well as some saprotrophic species that decompose organic matter. Members of this order often produce brightly colored, brittle-fleshed fruiting bodies, including the well-known genera Russula and Lactarius. They exhibit a wide range of morphological features, including gilled or coral-like structures, and typically have amyloid or ornamented spores. Russulales fungi are widely distributed across forests worldwide and play a crucial role in forest ecosystems by supporting tree health and contributing to nutrient cycling.
