Agree about white spines in mature specimens and also in karwinskiana ssp.nejapensis. Spines on younger ones usually have brownish tips. white hairs also better develop in older karwinskiana plants imho.

Re: 3 Mammillaria cacti IDs request
For the first one I could suggest M.karwinskiana, for the second - check M.rhodantha, M.pringlei or nivosa. When it blooms the flowers will help to narrow down the species.

Mammillaria bocasana would be my guess

Re: columnar identification
Thank you for your suggestion, Tom! it was indeed bought from a retail nursery, no tag. Alensis is a possibility, I am considering gaumeri as well. Guess I need to wait some more and see how it grows and possibly blooms..

Re: columnar identification
Thank you Anttisepp! it does remind of pachycladus, but at that age it should be already blue/bluish. Mine is as green as a cucumber.. Will keep growing it and observing if anything changes. I like the plant, name or no name

columnar identification
Hi, I have a columnar cactus that I cannot identify for some time. Guessing it might be one of the Pilosocereus species. Any help will be appreciated.

Re: 8 little cacti
Agree with anttisepp about M.haageana. Both perbella and formosa at that age are globose with flattened apex. Your plant is elongated, which is more often with young haageana (yours could be M.haageana ssp.elegans). Flowers could help to narrow it down.

Re: Pilosocereus
You are right, it is difficult to say at that age. P. pachycladus is possible, but I would also consider P. languinosus or P. glaucochrous.

Re: Matucana?
@nachtkrabb I am curious about Matucana fruits you mentioned. Have you seen seeds inside them? Did you have a chance to sow those seeds? From my experience, sometimes cacti produce fruits after being pollinated with other unrelated random cacti species that bloom nearby at the same time. The process...
