Maxillaria tenuifolia shriveled pseudobulbs

[SydneyH]

Two or three months ago I bought a bagged Maxillaria tenuifolia on the clearance bench at Lowe's. I have no idea why it was on clearance because it seemed to be in great shape. It came planted in spagnum. It started putting out a bunch of new pseudobulbs and roots so I eddidn't change the media.

In the last couple of weeks, though, the pseudobulbs started getting more wrinkled. The spagnum makes me nervous and the humidity here means it never dries out some weeks. I decided to change it to a bark and spagnum mix where it could get more air. When I changed it yesterday, I was expecting to see a bunch of rotted roots. Instead I saw some of the most beautiful orchid roots I've seen in a while with some new growth at the tips. So my question is, why are the pseudobulbs getting shriveled and should I worry about it? I've now inspected the plant from head to toe and it looks pretty darned healthy otherwise.
