I noticed these mushrooms growing under the redwood tree in front of the office on Monday. The cluster of cute little mushrooms has since morphed into these rather large fungi which seem to be fighting each other for space and sunlight.
Our resident doctor, cub scout leader, master of the outdoors tells me that they are called agaricus. He breaks one off and inspects the brown colored underside. Then he crushes the stem to show me the yellow hue deep within. Although eating them would not kill you, he remarks, they are part of the “lose your lunch bunch.”
