Catasetum Weirdness

[HighSeas]

I was wondering if you guys would take a look at this....It's my only Catesetum. (Tenebrosum) I bought it last summer and got it just as it was dropping it leaves. I parked him over my workstation in the orchid house to make sure he didn't get any water. There he roosted all winter long, all the while, my husband reminding me how ugly he is.

Towards the middle of January I noticed a "constriction" or narrowing toward the base of the larger pseudobulb. The other is unaffected. It's almost as if the pseudobulb dehydrated in that one spot and feels somewhat hollow when I gently squeeze it. No smell. No secretions and no visible sign of pathology. Have you ever seen this? What did I do wrong?





There are also two keiki's on the same pseudobulb. They emerged shortly after the new growth began to sprout.



I have virtually NO experience with Catesetums. Just ordered some sawdust to mix up with clay pellets and dolomite powder....Since their habitat does reflect that they like decay, I thought that idea sounded more to their liking than the orchiada I have them in.
