to the best of my knowledge, SOD has not made it here, yet. It sure has some of the symptoms. Last year there were two small cankers with black fluid (in small quantities) coming out. I hope and pray that is not the problem. Any one know of other vascular fungus oaks might get. There are what I have identified as golden scale on the tree and I read that is associated with Anthracnose...I didn't think I would see the wet, stain like marks on the stem and branches. Thanks!
