Stephanie, I couldn't sleep so I was looking (just on wikipedia) into your question. Its seems that Magnolias and tulip trees are not effected by this fungus, so that gives you another option. Its really too bad, the photo is so striking! I love the color even if it does signify a bad thing!
Originally I was thinking maybe eastern redbud, but it is listed as a 'Eudicot' and therefor susceptible.
