I don’t think Scleroderma.

Scleroderma when fresh has extensive rhizomorphs extending into the soil at the base. I don’t see those here. The interior has split into 7 rays, which more closely resembles Geaster or Geastrum. Finally, the outer peridium (the underside of the rays) has small scales on it. While Scleroderma can have those (rarely), it resembles Geaster/Geastrum more in my opinion. I have found Geaster up to 8 inches deep in woody humus, when the peridium is pure white and the gleba has not yet differentiated into spore-bearing material. To me this looks like Geaster after the spore mass (gleba) has already dispersed, probably by rain. Finally, unless the area has been under a complete deluge recently, there should have been some spore residue on the inside of the rays.
