Lichen

“On a lichen kick. Irresistible children’s book for budding mycologists. Reminder: “Lichens and mushrooms are distinct organisms; a mushroom is the temporary fruiting body of a fungus, while a lichen is a permanent, symbiotic colony combining fungi with algae or cyanobacteria. Mushrooms are typically short-lived, spore-producing structures, whereas lichens are long-lived, hardy organisms often found on rocks, soil, or trees.” .”
