Good morning Kam,
We had some extensive discussions a while back regarding galls, cysts, tumors. (mostly my big mouth ;-)
I believe they are all the same, although containing different organisms. Plants have galls that contain pathogens in early stages, as do cysts and tumors in humans, (which are galls in human form) Dr. Simoncini, the oncologist from Italy says all cancer is fungus and I believe it. At least for sure the tumor, which he kills within hours. Either way, I believe fungus is involved one way or another. Here's one of the links to discussions we've had.
CYSTS
Also want to mention that while I may not have the same black specks as anyone else, when I put my 'poppy seed' under the scope, it was coiled up fibers, same as the white 'salt' specks. Those suckers sure can be hard and compact, I tell ya.
