This one seems to lead to Couplet 35 of the Key to Genera of Perlodidae Nymphs and the genus Isoperla, but I'm skeptical that's correct based on the general look. I need to get it under the microscope to review several choices in the key, and it'll probably end up a different Perlodidae.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

I would like to thank you for taking the time to photograph and post these beautiful pictures. I'm 64 years old, and an avid fly fisherman. My new hobbie is taking pics of mayflies, and I'm getting excited. I've got a new tripod on order, and an excellent camera. I would find it a pleasure to share my photo's with everyone.
