Gymnosporangium

I was driving along today and saw a particularly striking example of Gymnosporangium juniperi-virginianae (cedar-apple rust) in action!  I saw at least three trees in the area with this amazing bright orange fungus, but one of them was completely covered!  Here are a few photos that I took:

  1. I just saw this for the first time in my mom's yard about a month ago. Very interesting.

  2. This was the first time I had actually seen it in the stage where it was bright orange. I had only seen the copper-colored galls before. Quite spectacular!
