Hello,
I have two Mammillarias and I am not sure about their species names. They are blooming at the moment which should make it easier to identify.
I have thought of M. fraileana (left cactus) and M. albicans (right).
It would be nice, if someone could help me with their ID!

Flower of the right cactus:
Kind regards,
Michaela
