Looks it is too late. The white stuff between spines looks like a mold. If the body is soft - it is done.
The infection might be caused by artificial flowers attaching. And too much water, a cactus like this doesn't need any water winter time.

These are among my favourites. I have heard that Lophophora plants are forbidden for keeping in collections in some states, is that true?

Lol looked in on the garden webs thread davew. Sadly many of the people claiming they would never buy those painted plants, indeed have and i was one of the many to point that they were dyed and had glued flowers on them, pretty funny how they all act like they never did it then would chastise me f...

These are the risks of online shopping now. In good old times we use to go buying plants to a local grower and seller in person at home and with a real basket. Mostly winter time, and lot of cacti were stored there in cases, some bare-rooted. And beyond the prepared phone order you could always say ...

Actually it stopped in August till Dec., I don't push it blooming keeping it quite dry.

Sure, I meant E. platyacanthus, but even for an young E. polycephalus the spines are impressive...

Retuse they are called. I quite like retuse Haworthias. Your Haworthias look nice. But you cheat! Plants always look nicer when they are wet, like yours. Thanks, Aiko. Actually just the 1st one is little sprayed by an oily solution, kind of anti-bug preparation. For other pictures I just added more...

Nice pictures so far, lovely plants! Some of my plants: https://farm8.staticflickr.com/7520/16295839276_3325889499_c.jpg Haworthia cymbiformis https://farm8.staticflickr.com/7565/16134223108_35885bdb64_c.jpg Haworthia herbacea https://farm8.staticflickr.com/7563/16320920302_038fa24d46_c.jpg Haworthi...

Oh, those spines are really impressive, I would say "oversized"... knowing that the mature plants will go almost bare, spineless at some point. Talking about the cold, traditionally most of the Northern hemisphere cold is around here. Even this winter is moving kind of weak -- above 0 at d...

Very good, cactusgrower313. But I would not rush these plants to grow right now and better keep it dormant. The sun is still not strong enough, and behind glass or plastic walls the spines will be weak and the pads - slim and ugly. The same apply to other Opuntias more or less too. Expect some norma...

My Opuntia fragilis has smaller pads and roots easy in spring or summer, not now. They can feel the season somehow, I think. That time roots appeared so strong that pads were pushed out of the ground where I stuck it in before. No problems, pads can wait till spring or some sun will shine on. May be...

I see this topic is still active and nobody is saying "The spring is behind the corner". But my Rebutia minuscula is showing that, almost in bloom: https://farm8.staticflickr.com/7528/16112365847_e2f2895fe7_c.jpg Or I just failed to provide to it cool enough spot where it could wait till r...

I had a similar found at the west end of Anza Borrego Park. E. engelmannii & F. cylindraceus were growing in cracks of the same granite boulder. Who knows, might be spacey enough deep in the cracks...

I also saw sprayed Mammillaria in the local Walmart just today.

I hope so, one day. Those are not even 2 years old yet.
