What looks like bruising on Lc. Fire Dance Patricia :(

[butterfly_muse]

Evening, guys!

I can't figure out what is going on on my Lc. Fire Dance Patricia's leaf. It looks almost like a human bruise would, but on the leaf. But when you hold the leaf up and look through it, it has tons of little black dots inside of it.

I recently moved all of my plants underneath of two LED lights for the winter, and it has come up since then, so I am wondering if it's "sunburn"? The surrounding leaves also look to have some yellow mottling in them, but the larger leaves are fine. It has also put out one whole new growth which is growing a sheath now, and you can see the second, smaller growth it's pushing up.

I have attached pictures of the leaf in question, surrounding leaves, and the whole plant.

What is this and how can I fix it, if it can be fixed?

Go to www.staugorchids.com. Read on guignadia. Keep away from your other plants.

Are you sure it is that? The spots only appear when it's held up to the light there are no raised lesions on the leaf. I have neem oil is that a good enough fungicide or should I find something else? I also have physan 20 but as I understand it that's a disinfectant...

There are many many different ailments on orchids. The staugorchid site gives you a brief tour of orchid afflictions. I have lots of orchids with lots of blemishes and nothing comes of them. That's why I guided you to that site. It gives you an overview of things to look for. I thought it was better than saying x y z and having it be just blemishes like mine have. Bu8t remember that blemishes "are" something. Isolate it for a week and see what develops. Hopefully it will be benign. Orchids are very resilient and can fight off a number of problems.

I would watch the leaf. I am the paranoid type when I see this sort of thing. I have had had some spots that, like James said, don't seem to cause trouble but sometimes it can be caused by a fungus or bacteria. It can be difficult to tell in the early stages.
