I've had two of my gymnocalyciums rot out on my. They simply stopped growing, after a month of no growth I unpotted one and the roots simply snapped off. The inside was rotted but not squishy? The outside of the plant was perfectly green and firm but the cactus was entirely rotted through.
Usually, in my experience, plants get squishy when rotted, but gymnocalyciums dont seem to rot the same way.

Dry rot perhaps?

I don’t know the cause, but I’ve seen it at a Mammilaria or two at the botanical garden. They look fine, but upon repotting them they’re hollow inside. A picture maybe?

Re: The Way Gymnocalyciums Rot
Didn't take one at the time. Was too frustrated at rot. I barely ever water, so idk. All my cacti grow outside so they do get nighttime humidity because i live near the ocean. Most cacti seem to be able to handle it, but I've had two gymnocalyciums dry rot on me.

Re: The Way Gymnocalyciums Rot
Yes, not all rots are mushy. My old Echinopsis ancitrophora (shown in my avatar picture) died a few years back during the winter when it was bone dry. It looked fine most of the winter, but just shriveled up when spring approached - dry and hard, not mushy. It looked like it was producing fruiting bodies of the rot organism, so I just got rid of it.
Fortunately, i had seed from it. Its daughters should be blooming size in a year or two.
