Identification Help

[greentree8]

Hello,

Can someone help me identify these cacti? I labeled them 'A, B, & C' for easier reference. Thanks for your help!

a some kind of parodia/ notocactus, mammulosus or similar
b-thelocactus hexaedrophorus
c thelocactus hexaedrophorus , older

I would say "A" is one of the "Gymnocalycioide" Notocacti which look similar to Gymnocalycium's = uebelmannianus, arachnites or crassigibbus. Now lumped into Parodia. However they had to change the name of uebelmannianus to Parodia werneri since a Parodia uebelmanniaianus already existed. However if placed under any other genus than Parodia the name reverts back to uebelmannianus.

Thank you! I'll have to do some research on those species to learn more about them.
