Re: ID request N° 14
thats definetly NOT any kind of mammilaria. Im getting a mediolobivia haeferniana vibe.
Re: ID request N° 14
Could also potentially be a sulcorebutia species?
Re: ID request N° 14
No it's not a Sulcorebutia. Sulcorebutia gets it's name from a sulcus = groove on top of the tubercle and Sulcorebutia is also now usually placed in Weingartia.
It is definitely an Aylostera I would say rather than Rebutia sensu stricto. Aylostera is now separated from Rebutia again since DNA Sequencing has proved they arise from different lines and the visual similarity which placed them together in morphological classifications like The New Cactus Lexicon is merely convergence from inhabiting similar habitats.
The links below explain why morphological classifications lumped Rebutia and Aylostera together in the past, but DNA Sequencing now separates them.

And if you wish to go into the subject in even more depth. As you can see from this first link below there are now far more Aylostera's than Rebutia's though most were lumped under Rebutia in the past.

Re: ID request N° 14
Don't Aylosteras have wooly flower tubes?
My understaing is rebutia= naked tubes, aylostera= wooly tubes

I think the amount of wool or bristles is a matter of degree. The main visual difference is in Rebutia the style is free on the top of the ovary, whist in the Aylostera/Mediolobivia group it is fused solid to the tube at the bottom.
This old book by Brian Fearn and Les Percy from the days when they were all called Rebutia shows flower sections (scroll down to change pages).

Note the difference to the free style on the top of the ovary on the Rebutia marsoneri internal flower section on p.10, to the style fused to the bottom part of the tube on p.11 in Aylostera muscula (then named a Rebutia).

Aylostera deminuta ?
J. Lode lists 30 species and possible subspecies of this genus.
