My Jane Magnolia has a dark black fungus from the ground 1/2 up one of the main branches. Also, there are white bump like growths that look kind of like small mushrooms all over my plant. I cleaned some of it off and it has a pinkish liquid inside. I've seen lots of fungus on plants and trees but nothing like this. I just noticed it today and hope you can give me some idea of what it is and how to get rid of it before it kills my plant. Thanks
