Interestingly, one of my specimens seems to have overcome it's 'crestata' deformity in one area and one 3" finger of regular M. Elongata growth with a few normal offsets is growing on the edge of one of my brains.
I will attempt to graft a piece of this to a hardy base, I believe it's problems with rot are due to the convoluted areas adjacent to the moist soil. I try to avoid pouring water directly in the 'brain' because it's likely there are areas in there where it could pool and give the poor thing an aneurism.

This is a low, twisted yellow cactus that forms a mound that looks just like half a brain, complete with all the convolutions. Spines abbreviated making this a user friendly plant- hard to actually poke yourself with this one. Tends to rot and very slow to grow. I have never seen one actually get much larger myself.
