Mislabeled cactus, another ID please?
Ok, so I posted this elsewhere as I feel like I keep asking you all to ID things for me once a month, and I feel bad about that because every other post here is an ID request. However, it seems as if this is the only place my plants get IDs that are correct and not just a bunch of wrong guesses. Those that ID things around here are a bunch of pros, so this won't be my last request I'm sure. Seriously, thank you for being so helpful here.
So onto my request. I got this labeled as Rebutia krainziana. It isn't, but I can't figure out what it is. I got some Parodia and Notocactus guesses so maybe it's one of those genus's. It's blooming from the top and pushes out a fuzzy areole before the petals are visible.
