Thanks to you both for the information. Looks like mine will need to be
removed. :-(

They are definitely dead. Will it harm the plant to leave them and let
"nature take it's course"? It's the rot angle I'm afraid of. Could it
hurt the rest of the plant, or is my cure worse than the problem.

Thanks to you for your response and everyone else here who has answered my
questions in the past.

Let me amend my answer. If the old bulbs are healthy and have leaves and
you want to remove them, just pot them up as a division. If there are no
leaves but the bulbs are healthy, then you may need to treat them
differently in order to produce the new plant.

The answer to this depends on the condition of the pseudobulbs. You say
they turn yellow. Are they shrivelled? Do they still have leaves? A
healthy bulb doesn't necessarily need to be removed. In many cases,
healthy pseudobulbs can be developed into new plants. If they are
shrivelled up or soft then they should be excised and discarded.

You mentioned damage that occurs when you remove old pseudobulbs. Many
times the plant will tell you where it wants to be divided, pulling
apart easily. If that doesn't work, take care to cut between the old and
new pbulbs without damaging eyes on the new ones. If you are removing a
pbulb that has any sign of rot, be sure to cut away tissue until you see
no more evidence of disease. When you cut something from an orchid, you
need to seal the wound. My personal preference for this is a compound of
Elmer's Glue and cinnamon.

Hope this helps.

What do you do with the old pseudo-bulbs, as the plant moves outward
and develops new growth? As they grow turn I'm always tempted to
remove them, but I seem to find I cause more damage than help. I'm
facing this with a liparis grossa currently. Thanks once again for
your help.
