Pseudobulb with no leaf

Just curious, what should I do... I have a nice and healty Bulbophyllum growing in my terrarium. Everything is nice and dandy, except one leaf dropped long time ago and all that's left is a nice and healty pseudobulb. Should I just leave it alone or cut it off and put a bit of sulphur on it?

Here's a pic, but it's a poor one. The leafless pseudobulb is at the top, sticking straight up, hidden behind the leaf. There is a 2nd one at 7 o'clock too. Suggestions would be appreciated!



EDIT: oops...I posted this from Admin account, sorry, this is Marty

Leave it alone. Old pseudobulbs serve as nutrient and water storage vessels connected to the rest of the "colony" via the rhizome. Besides, if it's still green, it can still photosynthsize and create nutrition!

Fair enough. Thanks. I suspected that it's still practically behaving like a leaf. It's quite big and green, so really all it lost was the flat photosynthetic part, but since it's so close to the light, it's managing, without it !

Thanks
