Overview

Geastrum coronatum is an inedible species of mushroom belonging to the genus Geastrum, or earthstar fungi. Christian Hendrik Persoon published the first description of Geastrum coronatum in 1801.

The Crowned Earthstar faces severe population decline primarily due to habitat loss from agricultural expansion and urban development in its limited range. Climate change and altered precipitation patterns further threaten this fungus by disrupting the specific soil and moisture conditions it requires for reproduction and survival.
