Photographer David Reid takes these pictures with his iPhone as he walks around a local field.
Hannes Bergthaller and I were talking about how when you find one mushroom, you suddenly start seeing loads. We wondered whether there was some hard wiring in the brain that makes this so, mushrooms being a rich source of many good things. What Hannes and I have both experienced, and I wonder whether David agrees, is that when you find one mushroom, it appears as if the field in which they appear seems to recede into the background and the mushrooms stand out, as if they're calling you.
