Neon orange guck

I went out to check on my garden tonight after work and found this "stuff" on the backs of the leaves of one of my raspberry? Blackberry? plants (they are planted near each other and I have trouble identifying until the fruit comes on).

Is it a fungus? Bug eggs? spray paint? I looked on Ohioline, it could be orange rust http://ohioline.osu.edu/hyg-fact/3000/pdf/3010.pdf which does not infect red raspberries, (great! My Carolines and Autumn Brittens might be safe!) just black raspberries or blackberries - or possibly late leaf rust which ONLY affects red raspberries, according to MSU extension. http://www.canr.msu.edu/vanburen/e-1730.htm Question - how do I figure out which it is? Or does it really matter? I guess I just have to dig it up and "destroy" it. (How do I do that? Do I burn it or put it in the trash pickup?)
