Do you have a photo? It would help with advice.

The water advice is pretty useless. Besides it doesn't any of my original questions.

Lot of SPAM on the forums recently. Just ignore. I can't tell anything from your pictures. Post a shot of the whole plant. The roots look fine to me. I can see new root growth and a bunch of old roots. Normal.

I can't see the plant. What makes you think it has a fungal problem? I doubt you do, my guess is overwatering and not enough light.

The main problem here is the positive id as an Odontoglossum. Maybe it is one of Intergenerics that will tolerate warmer summer temperatures? Intergeneric = Odontoglossum with one or more other Genera.
In any case the pics posted indicate that it needs repotting but maybe that has to be left till spring....depends on your growing conditions.

Sorry this is the best that I can do picture wise.

I received this after it had flowered so pictures of the flowers are useless to me.

Just trying to help......there are some culture notes in the link.
Cannot say what you have by just looking at the pseudobulbs, there are thousands upon thousands of orchid hybrids in the "oncidium" sub-tribe, the point about some of the species in the Genera Odontoglossum is that they are cloud forest orchids and do not like high temperatures (over about 90F) and like to be kept evenly moist. Anyway the notes i found might assist.

Thanks
I actually came across that site when I found out what type of orchid I had. However, the reddish brownish spots concerned me. I assumed it was the fungus that they can get.

These plants get spots. Usually when exposed to high light. Its normal. The plant looks dry. If you want to repot, you can do it now.

Looks like a new growth starting. Otherwise, water when almost dry and follow the good link from Arthur.

It is not a fungus. While some discoloration may be due to sun burn or even from excesss salts in the water the spots especially at the leaf base just above the pseudobulb look like they are lesions while there are spots on the bulbs.
These may be two separate issues. The lesions could be viral in nature and I would think so if they turn black over the course of time.
In these types of orchids viral infections are rather commonplace.
What concerns me most about your plants is that they are very dried out and need to be watered more often. And repotting into a larger pot using a bark product wouldn't hurt either! For this type I would use a net pot as they like to dry out between waterings that should occur at least daily when they are growing new pseudobulbs. As they are done flowering and look like no new growths are beginning yet now is the time to repot.

Okay, I'll water it a little more. I don't use tap water but the bottle stuff. There are no black spots. I think I'll wait until the new growth is taller to repot it. Since I already broke one of the new growth off trying to put in back into the metal pot the first time I watered. BTW what is a net pot?

Net pots are plastic baskets, taller than wide, with holes all over the pot. I use net pots for anything that needs constant moisture but also wants "air" to the roots.

If you have a hydroponics store in your area they carry them.
