Nobody has seen these?

Maybe warasii for the Parodia,

Im actually most conflicted about that one. Ive issues telling warasii and magnifica apart, but the general rule was: warasii was bright green, magnifica was glauscent and darker green. Having said that , i still have my doubts, since id like to think ive owned both plants at a certain point of time.

Now , my issue is, doubting the ID due the spination because knowing its a juvenile specimen, and somehow less dense then either of those 2 species.

Some know of any (eriocactus or notocactus) hybrids between these plants?
