…have a look at the conversation from the other thread, http://mushroomobserver.org/146086

This was my last post in said conversation:

I looked through those links, and I didn’t find anything that swayed me one way or the other…….

However I now think IF these are indeed black knot, those cankers would be considered Fusicladium, an asexual form of black knot fungus.

“The anamorph, or asexual, stage of the black knot fungus (Figure 8a) is a species of Fusicladium, that produces abundant olive-green conidia during the summer on the surfaces of one-year-old knots (Figure 9). It appears that the infection capabilities of the conidia are quite limited. Therefore, management strategies are focused on ascospore development and infection processes”

Those things are definitely one year old, it would be interesting to see if conidia or ascospores are found on these large old conks."
