All along the trail, I saw huge white mushrooms. Where did these come from? They have suddenly appeared in the lawns, under the trees, next to the sidewalks. If they are disturbed, i.e. pulled up, they return in the same spot. When they emerge from the ground, they push the soil up above them leaving a dirt pile. My spouse asked me how mushrooms spread and I’m not sure. By their rhizomes? By spores? It warrants further attention. I thought they only grew in moist, dark places, neither of which describe Boulder. What other surprises do these fungi hold?
