One of the characteristics is whether it has a pseudo-stipe attached to rhizomorphs, or not. To see this feature is it necessary to dig the sporocarp, and often to slice it through the center of the pseudo-stipe. If there is yellow or reddish staining, it is oe group of Sclerodermas. If not it is another group.

The cracks in your obs. are typical of rapid dehydration, especially in very dry conditions. I would guess that peridium, that looks grayisih in your photos, is actually a blue-purple or purple-black color. The peridium should change color… or not. A photo of the cut sporocarp is necessary for identification purposes.
