Typically found in soil, Astraeus species are part of natural ecosystems, helping decompose organic matter. They are also prized in some regions for culinary use. Overall, Astraeus fungi play a vital role in nutrient cycling and display unique, striking appearances that make them interesting both ecologically and aesthetically.
