Distribution: Earthstars are not particularly abundant in forested areas of the PNW. Many species are more characteristic of drier woodlands and even deserts, so the diversity of earthstars and many other gasteromycetes is much higher in the southwestern U.S. G. saccatum is widely distributed in the Northern Hemisphere and we have seen it, or a dead-ringer for it, in Tasmania, Australia.
Geastrum triplexcollared earthstar, saucered earthstar
