Thanks be to the Internet. Well, the notion I was harboring all along...that this coloration was fungal, is true. Chlorociboria aeruginascens or C. aeruginosa. Bless those who study fungus and organic chemistry. My phthalocyanine (blue-green pigment) was not so wrong-in fact led me in the right direction. Napthalocyanine is a derivative of the former and somehow the pigment of these fungi are connected to napthaquinone. Both naptha and now I am thoroughly out of my league. Apparently Green Stain oak is a commodity and is used for green colored wood projects. Check out the links to see:

Very cool! Thanks for the edification. Oh, and now I'm craving mushrooms....
