Woodland garden fungal outbreak! Maybe I can better remove it if I know what I'm dealing with. What is this white fluff on the young shoots of the tree? The surrounding bark and ground have a black powder, in addition to the moss now browned under the infected area.

Can you post a photo of it? That would help us to give you an ID.

I hope someone knows what this is. Sort of resembles powdery mildew, but what I've seen usually gets on the leaves as much on the stems and your photo doesn't indicate that.

I'm replying to my own thread for the sake of education! This isn't a fungus at all! It's the waxy fluff of the Woolly Alder Aphid on Alnus glutinosa. The branches were removed and the trunk blasted with water, though this tree is soon to be cut down due to invasive potential.

Thanks for posting this. I was really curious. I had tried to make it whiteflies, but that didn't really look right. But it didn't quite look like powdery mildew, either Smiling . .
