Plant Diseases/Willow tree fungus?

I recently discovered the same type of growth on my willow tree. Please note that I have very little experience or expertise with anything green, so this is not an expert opinion. This was the first article I found, but I love my willow so I did a lot of additional research. Everything else I found describes these as "adventitious roots" which may be triggered by excessive wet weather. That fits my situation because we have had constant rain for several weeks. Here is one of the articles. https://uconnladybug.wordpress.com/2009/07/
