Collared Earthstar (Geastrum triplex)

            Fascinating species: "The fruiting bodies of several earthstars are hygroscopic: in dry weather the "petals" will dry and curl up around the soft spore sac, protecting it. In this state, often the whole fungus becomes detached from the ground and may roll around like a tumbleweed. Once mature, their exoperidium splits into a variable number of rays, which give Geastrum their visible star shape. The exoperidial rays are there to protect the endoperidial body and orchestrate spore dispersal. In wetter weather, the "petals" moisten and uncurl; some even curl backward lifting the spore sac up. This allows rain or animals to hit the spore sac so, emitting spores when enough moisture is present for them to germinate and establish."
