One of the best controls for fungal growth is to prune off the affected plant parts. Unfortunately azaleas spend the summer months developing flower buds for the following spring's floral display. If you prune now, you'll lose next season's flowers. But, pruning will remove the fungus so I'd vote for pruning now and removing the debris from the garden. Wish I had more solutions for you!
