looks like some dank to me... it would be called ASH if that nug crossed my path and unless your gettin weed directly from the grower or a medical supplier its more than likely gonna be mislabeled or have some made up name anyways... my boy always has like 4 different kinds of VERY high quality bud and i know half the time he has no idea what the exact strain is...but he still labels them just for reference...

dont get me wrong...some strains are easily identified by their appearance..i can always spot some sour diesel just by lookin at it and smellin it...but there are SOOO many strains now that its almost impossible for a street dealer to keep up with all of them...if he calls it blue dream then i guess thats what it is
