silver maple

i've noticed a flat, bright-red blotchy "rash" or discoloration on the underneath of several leaves of my silver maple. what is this and how do you treat it if necessary?

I don't know. People will ban me but, I'd simply spray with both an insecticide and a fungicide as directed on the label. Personally, I'd choose liquid copper for my fungicide and either a horticultural oil or pyrethren derivative, or an inorganic insecticide. In any event, all listed above would do the job. Continue as needed. Follow the label for application intervals.
