Help ID Mammillaria

Hello,

I would like to get some help to ID these 2 little Mammillaria :

Thank you very much.

It would be better if these photos were in focus. I for one can't identify them like this. Please retake the photos and look at them before you post them here.

Well, the trouble is that these pictures are totally clean but by posting them throughout the first icon so as to post a picture, the quality become bad.
However, I can not use external links with my pictures of better quality because I need to wait 7 days before doing this...

Thank you

OK, now that we have better images, I think that the first is a cristate form of M. crinita. I'll come back to you on the second, I know it but can't put a name to it, I need to get to my greenhouse, but its a bit too cold at the moment!

Thank you very much, so you think so Mammillaria zeilmanniana fma. cristata ?

To be sure of it being zeilmanniana you really need to see the flowers. M. crinita as defined in the New Cactus Lexicon, includes a wide variety of forms, some previously called species. I find it difficult to understand sometimes the logic of such lumping, but it is true that even in a single location the plants can be very variable.

The first one seems to have quite conical tubercles and the centrals are fairly long. I would say it's not Zeilmanniana which has short centrals and rounded tubercles, and certainly Crinita forms confuse me. I would have called it for Rekoi ( Pullihamata form possibly ). I stand to be corrected though, i'm nowhere new as knowledgable as many on this forum.

I think that the radial spines on the first plant are too long and "whispy" to be of the rekoi affiliation. Looking at it again,, I wonder if it might be what is now called M. bocasana ssp. eschauzieri or previousy M. hirsuta, cristate obviously. The second looks close to M. matudae, maybe what is named as M. compacticaulis? Not entirely sure, but I am by no means certain.
