I Talk to the Trees
Man, that was a stretch, but you try figuring out a rock lyric with the word “lichen” in it. The tree trimmers were kind enough to leave all of the oak tree trimmings with “green stuff” on them in my yard, cut to manageable lengths and neatly piled. When harvested, I had a quart mason jar filled with (primarily) Parmotrema Praesorediosum (I looked it up.) I have a pint jar with about a quarter cup of it marinading in my bathroom, despite it failing the bleach test. (You look it up.) Hope springs eternal and all that.
Today I am about to boil up the rest of it and see what happens.
