Default Dark spot on the leaf...

What do you think about this spot? I hope is not a virus.

I am ready to cut it, but I am not sure...

I think it is some sort of burn.

It is not a virus.

Good news?

But, the black area is spreading? Should I cut it and put some cinnamon?

Thanks a lot!

I would cut that entire leaf off before it reached the crown, it's rot.

I've seen this sort of thing happen when a leave is touching something hot or wet. Another plant or a pot.
Sometimes it is trauma.
Definitely cut it before it affects the rest of the plant.

I agree with the others. Sure looks like rot. If you only cut out the rot, the leaf will be abnormal so I would cut the whole leaf and use cinamon.

I don't do most Dendros or large, "floofy orchids". For me it's minis (like Angraecoides), Paphs, and others that crept in somewhere along the line. See my orchid list for complete collection (usually not current.)

I did this. Something in between cutting out the leaf and the area, because only 3 leaves remain...

Thanks for the advices.

Actually, that should work just fine. I did this with a Bulbo a had problems with and it worked just fine. You did treat the cut edge, right?
