Sick pole bean plants

My pole bean plants have dozens of white spots on their leaves. I've posted photos of both the top and bottom of the leaf. Anybody know what these are and what can be done about them? Thanks very much in advance!

 

I have never seen that before. I couldn't find anything like it in searches. Such neat little clusters. Insect eggs? The neat ring structure makes me think it might be a fungus or even viral growth. I would remove all infected leaves and dispose them as soon as possible.

 

Thanks Eric - I will do that.

 

This should be a pest. Can't recall the name.
It's not fungal nor bacterial nor viral problem.

 

Thank you Sulev. An interesting thing is that it was only the lower 2 leaves of each plant that were affected, very near ground level. The rest of the plant seems entirely unscathed. I picked off all the infected leaves, and am hoping for the best.

 

Fairly certain it is/was bean rust: Eddie’s Corner: Rust on Green Beans - North Georgia Master Gardeners

"The first symptoms of rust on the foliage are very small, white, slightly raised spots or pimples, which may be surrounded by a yellow halo. "
