Top Of Norway Spruce Tree Has Black Growth That Looks Like Swollen Pine Cones

Question From: c. Alpaugh - Bethlehem, Pennsylvania, United States
Q: We have a tall tree which may be a Norway spruce, its about 30 feet. The top of the tree has some black looking "growth" which could look like swollen black pine cones. I doubt thats what it is, but have no idea what to think. Is this a bug,or a disease Problem?

A: If it were my tree I would have an onsite inspection from a certified arborist, which I am not. To find one in your area go to and enter your zip code. Best And Happy Yardening, Nancy
