You know, now that there are several examples of edema photos on Catasetum leaves, I have definitely had this happen occasionally to some of my collection. I never paid much attention to it since the plant kept growing without any problems. Thanks for bringing this up! I definitely learned something here!

Not quite! That article explicitly states to stop watering during dormancy in several places.
This species is considered tricky to grow and many experienced growers can't keep them alive. I remember when I first tried (maybe 12 years ago? I think the thread is buried somewhere on OB), I ended up killing several because I grew them wet during dormancy. When Facebook became the gathering place for orchid growers, I started asking my Brazilian friends how they successfully grew theirs. They all said the same thing: they treat denticulatum just like all the other Catasetums and give them a dry rest. I've had success growing this one ever since and have even gotten female flowers!
