So looking at the photo of the Crispa example, am I right in saying that Crispas have bumps (not sure of the technical term) down the column? Do they go all the way down or just around the underside of the disc?

The technical term is "verrucae". No, they don't go all the way down. Doreensis verrucae and arranged in obvious rows. Crispa verrucae are more random in placement.
Great shot Todd. Kinda hard to ignore the hole in the foot though. It looks like a rabbit.
