a better name for this would be Elaphomyces muricatus complex, since spores are not provided. This obs. has tiny clumps of spores embedded in the peridium.

There are many Elaphomyces in the world, and it is difficult to separate them without microscopy. I think it safe to call this obs. and your other obs. (200087?) different species, based only on the size of the spore clusters within the peridium. Tsuga heterophylla may have a different cluster of species than Picea does, but it would be difficult to separate them based solely on host species.
