I don't believe this is 'Scarlet Ball.' I think it might be a Parodia (not certain), but I believe it's another species of Parodia.
@zuzu, I don't believe Orsola has been on here since 2016 (well, at least posting). There are three other images that Orsola posted that I don't believe fit this species of Parodia. I was just tagging you in case Orsola doesn't respond at some point. I'm unsure where to place the pictures as I'm unsure if they are that of a Parodia (is there a generic "cactus" entry?
).
