A mushroom-based lunch at the class on mushroom cultivation that I attended. The main dish is based on Pleurotus and I can tell you that it was absolutely delicious. Gaia is wise and benevolent in many of her manifestations!
I took a 2-day full-immersion class on mushroom cultivation. I am not sure that I can engage in this activity myself, it is a full-time job, not really suitable as a hobby. But it is surely a welcome respite from the daily, horrible news we are receiving from all over the world. It is fortunate that there are still people who spend their time doing something good and useful, and may Gaia bless them for what they are doing!
Mushrooms are not holobionts themselves, but they are part
of many holobionts, not least forming the "rhizosphere," the
all-important layer that keeps Earth's "skin", its fertile soil alive. And you
may know that fungi are symbionts of the human organism, even
though their role is still largely unknown.
