P. hadriani - purplish volva.
Mutinus caninus - the head not wider than the stem.
What the egg looks like inside before one hatches.

You thought those two were rare, these three are extremely rare.
Dictyophora duplicata - like Phallus but with a bridal-like veil!
Lysurus cruciatus - the head is ribbed like a withered claw that had a Harry Potter spell performed on it.
L. periphragmoides - pinkish stem, top more of a lattice than a claw.
Clathrus ruber - a red lattice work. Not really club shaped, but what would you call it?
Pseudocolus fusiformis - orange tentacles fused at the tips.
There should be a specialized book on this group, I would buy it.
