Copiapoa cinerea?

Lobivia/Echinopsis winteriana?

Nope. And nope. The mystery continues.

Cereus halloweeneespinus? ;)

Ha ha, good one Joyce!

How about Copiapoa dura?

I suspect it is time to put a stop to some rumours ... not a Copiapoa ... not a Lobivia ... not a non-Lobivia Echinopsis.

And it is a live cactus, not a Halloween decoration :)

Is it South American?

Al

A mamm.?

Rather than answer the twenty questions just yet, I'll offer a slightly wider shot as a clue. I hope this doesn't make it too easy.

Here is a link that might be useful: Matucana madisoniorum

I *knew* the wider shot would be too easy for you guys :)

nice pic .ihave one of these cacti too ..... but the one i have has no spines...just wondering if that is normal or not , i've seen some that are really spiney and some that are sparse
wish mine has those colors though .bought the one i ahve because it was spineless thought it looked sorta neat , but after seeing this one i think i'd prefer some colored spines LoL

(Sub)Matucana madisoniorum can appear largely spineless but even the spineless ones will often have a few spines on some areoles or a tuft of spines at the top.

Mine has one or two grey spines on the lowest areoles, then a band of areoles with no spines, then the newest areoles have these dark spines weith orange bases.
