What's this on my 'chid's leaf?

[butterfly_muse]

Evening, guys! I was going over my orchids this evening and I noticed some bumpies on a new acquisition. As you will notice in the pictures, there's a split in that leaf (it came to me that way), which may or may not have something to do with it.

I have isolated the orchid and sprayed everyone with some neem oil. Any idea what it might be?

I have posted pictures of two separate leaves.

Thanks!
