Cyanescens

This mushroom prefers to grow on wood chips especially in and along the perimeter of mulched plant beds in urban areas. In the wild, they grow on lignin-rich substrates. Lignin is found in wood and bark, and in other rigid parts of the plant which do not rot easily.

Fortunately for fans, Cyanescens is rapidly growing and expanding even in areas where it is not native because of the rising number of people who use mulch to control weeds. In the United States, Cyanescens occurs mainly in the Pacific Northwest, south of the San Francisco Bay Area. It can also be found in areas such as Western Europe, Central Europe, New Zealand, and parts of West Asia (Iran).
