Blue stain on Spruce tree
Another white day, but as you see i found some color.
What i call a white day, you maybe call a grey day. But out here in the woods it's white, it's light.
About the photo; as i was marking the trail towards the meadow, Which i marked with yellow ticker tape, I came upon this healthy looking big Spruce tree.
I had never seen this blue color on bark. The yellowish white is Spruce sap (pitch). and the orange is the inside of the tree.
That the bark is coming of, maybe means that the tree is not so healthy.
I wonder if the blue is; blue stain fungi (Ophiostoma sp.)
which is mentioned with the occurrence of the Spruce Bark Beetle.
If you know for sure, what this Blue is, please let me know. Thanks
