make this E. muricatus group. E. granulatus has no spores within the peridium.

… suggests that these were the host for your collection of Cordyceps capatata, or at least are parasitized by another fungus.

I cannot see spore clumps in the peridium, and the external warts are consistent with the E. granulatus group. Which one I cannot say. I suspect, but cannot prove, that you have parasitized specimens, perhaps B. parasiticus or other parasitic mushroom is colonizing them.
