The blue roundhead can be found in mixed forests, heaths, meadows, pastures, grassland areas, but also in roadsides, gardens, lawns, parks, and landscaping and waste areas. This fungus feeds on decaying organic matter, thus its substrates are leaf litter and other types of organic debris, including wood chip mulch.
