What I found, in abundance, were lichens — in more shapes, sizes, and colors than I’d ever seen in my life. “Lichens” was later published in a literary magazine and in my first book, a collection of mostly environmental poems. I started by poring over two mushroom guides that had long sat on my shelves. I bought Merlin Sheldrake’s best-selling book “Entangled Life,” about the ecology, biology, economics, gastronomy, and spiritual aspects of kingdom fungi. My encounters with spaces and species, including fungi, have allowed me to gauge the passage of time differently.
