Lichen

About this time of year I start to get hungry for green and when I can take my eyes away from the mushrooms and other fungi I enjoy the interesting green of the lichens that grow so well at this time of year. Actually even when I'm looking at lichens I'm looking at fungi because lichen are part fungi. They are actually two kinds of plant intimately joined together for mutual benefit - a mycobiont (the fungi part) and a phycobiont (the photosynthetic part - usually an alga of some kind).
