Sap from an insect? What could this be? No pic

brass_tacks(8b/GA)June 26, 2010

Sure hope someone will know what is causing what I'll describe -- a shiny, dark area on a branch catches the eye and the area looks like it would be sticky, but pressing it, it is hard. One branch I discovered today actually had a drip of the substance that had solidified. The drip had a rosin color -- like the color of violin rosin -- an orangy brown. I've only seen this on the limbs.

What kind of tree? If a conifer of some kind, it could be resin.
