Does anyone else think this plant is a compot that never got separated when it was large enough to do so? That would explain why a plant this size hasn't bloomed even though it's large and getting plenty of sun. Its not one large mature plant, but rather lots and lots of small immature plants.

isurus79 do you suggest to divide the plant? Actually accidentally a small part got broken from it and I planted it separately( 3 years back), that plant is also growing( only growing). I don't even see any root coming out of the pot so I don't think it is root bound either..I have stopped buying Cattleyas for this reason!

Fungal black spot. It will spread very slowly but eventually kill the plant. But it is easy to stop. Take a razor blade and carefully cut off the black part into green leaf tissue. Leave none of the black on the leaf. Dab some cinnamon powder onto the cut edges. It will survive. No problem. I don't have any pics that I can find but as I do mostly rescues I get this condition all the time. It's not a concern unless you are growing a very nice collection or growing for sale.

Are the black spots squishy? Does anything ooze out if you squeeze the spots or does the "skin" peel back easily if touched?

Same consistency, no ooze or peeling easily.

Probably sunburn then.

Interesting supposition Steve. It would be interesting to repot this and see. I agree mainly because I see no older pbulbs or leaves. They are all the same size and age from what I can see.
