This research investigated the relationship between soil bacteria and an economically valuable wild mushroom (Russula griseocarnosa) that cannot be artificially cultivated. The study found that specific bacterial communities and soil conditions are essential for the mushroom’s growth. This has important real-world implications: • Better understanding of these relationships could help develop methods to cultivate this valuable mushroom species • The findings can guide conservation efforts to protect natural habitats where these mushrooms grow • Knowledge of beneficial bacteria could lead to development of specialized fertilizers to promote mushroom growth • The research provides insights into sustainable harvesting practices for wild mushrooms • The findings contribute to understanding complex ecological relationships in forest soils
