The Grey Falsebolete (Boletopsis grisea) is an important fungus species because it can serve as a biomonitor of air pollution with heavy metals. It absorbs heavy metals from the atmosphere and concentrates them in its fruiting body, allowing scientists to sample its edible portion to measure the levels of heavy metals in the surrounding environment. This fungus is also an important source of antioxidants, which can help ward off diseases like cardiovascular disease and cancer. Additionally, Boletopsis grisea is a valuable food source for many species of animals, including humans.
