Geastrum pectinatum is an inedible species of mushroom belonging to the earthstar family of fungi. Although young specimens are spherical, fruit body development involves the outer layer of tissue splitting open like a star into 7-10 pointed rays that eventually bend back to point downward, revealing a small broad spore sac. There is a distinct conical opening (peristome) at the top of the spore sac that is up to 8 mm long. It is commonly known as the beaked earthstar or the beret earthstar, in reference to the shape of the spore sac and its prominent, protruding peristome ?Credit: BSpragg
