Brand new catasetums arrived with black spots on pseudobulbs... help!

[Kristaz]

I received this Catasetum expansum, along with many other orchids, from Ecuagenera on Monday, Feb 28th (so I've not yet had them a week) . This and the other Catasetum had leaves, (so assuming it's not dormant) and were shipped with moist spagh, so once I got them in their vanda boxes I watered them. I noticed these black spots so I spayed it with a fungicidal. (No other plants had the black spots). During this past week, both catesetums have lost al their leaves, which I'm sure is due to the colder weather here, and maybe a little shock, but one also formed the beginning of a new pseudo bulb today. I am not sure if I should cut off this large pseudobulbs with the black spots so the rest of the plant doesn't get it? I guess I am worried that could be too much, since I'm sure it travelled for quite a while. Any advice would be appreciated..thank you.
