Potinara-New shoot is white?

[Helen]

Hi all,
Some of you may be following the story of my Potinara Red Crab....the new shoot had to be cut off part way due to some type of virus or root.....it has stopped growing (of course). I decided to repot because the pot was way too big for it...in doing so, I noticed a 3/4 inch white pseudobulb growing from way underneath the bark....I decided to not cover it up with bark when I repotted yesterday...

Has anyone else had this happen to them? where the pseudobulb is white? Probably from no light??

Did I do the right thing?

This poor thing has been trying it's best to survive....it tried to bloom (blasted when rec'd in March07), pseudobulb went bad, original roots in very bad shape, pot too big...etc.. now a little white pseudobulb

Thanks again everyone..
