Recognized by sight: 2nd photo nearly defines Scleroderma polyrhizum. So this proposed name applies only to that photo. Top photo to me looks more like S. areolatum. Spore size reported by Darvin could apply to either species. I’m not convinced these are photos of the same species. The peridium of S. polyrhizum splits and elevates the spore mass (gleba) similar to both Geastrum and Astraeus earth stars.
