Mammillaria easoi

I bought a mammillaria at a club meeting, part of a deceased member's collection. The label shows M. easoi with the number 953 (which could be the member's collection number). I am unable to find this species on any of the usual websites or on Google. Does anyone have an alternative name? See photos below.

I think you have a misspelling of M. casoi which is a Synonym of M. mystax. M.mystax should have bristles in the axils. The plants originally referred to M. casoi are found with very long central spines.

That looks about right. Many thanks Amante.

i think that here we have not a m.mystax.
your plant could be m.mammillaris.
look at here...
is possible?

But M. mammillaris has wool between the tubercles, the one shown by rodsmith hasn't. Its tubercles are more angular and the spines are different.

is correct your suggestion amante.
tobercules in m.mammillaris are conical, while in m.mystax are four- six angled.
this photo from mammillarias.net cuold be agree with you....

Thanks for all your help & suggestions. Taking everything into account I believe M. mystax is the correct identification.
