Bright orange spots (fungi?) on Blue Flax

Question

I have blue flax from High Country Gardens and the entire lower half of both my 3+ year old plants are covered with fine orange dots. It seems to be making the plants wilt. I am thinking fungus. What could it be? How would I identify it and treat it? Thanks so much!
