Radiigera has a capitate columella (interior stem-like structure), from which spore-bearing rays radiate outward in all directions. The peridium (exterior) is thick like Radiigera. This is an immature specimen. Not collected often enough to say how far away from maturity it is. NICE FIND!
Radiigera is in the Basidiomycota, and the Geastraceae. It is a generally underground (hypogeous) fungi that relies on animal mycophagy for dispersal.
According to my source, “Radiigera species are essentially earthstars (Geastrum spp.) that remain hypogeous and never open up, Small mammals dig them up to eat the thick peridium and discard the spores. Early collectors would find the discarded mass of spores and fibers lying loose on logs or tree limbs and misinterpret them as a slime mold. The black mass of spores and fibers would not excite the appetite of human diners.”
