The "ring" explained
"These rings are sometimes of very ancient date, and attain such enormous dimensions as to be distinctly visible on a hill-side for a great distance. It is believed that they originate from a single fungus whose growth renders the soil immediately beneath unfit for its reproduction. The spawn, however, spreads all around, and in the second year produces a crop, whose spawn spreads again, the exhausted soil behind forbidding its return in that direction. Thus the circle is continually increased, and extends indefinitely till some cause intervenes to destroy it. If the spawn does not spread on all sides at first, an arc of a circle only is produced. The manure arising from the dead fungi of former years makes the grass peculiarly vigorous around, so as to render the circle visible even when there is no external appearance of fungus, and the contrast is often stronger from that behind being killed by the old spawn. This mode of growth is far more common than is supposed, and may be observed constantly in our woods, where the spawn can spread only in the soil or among the leaves and decaying fragments which cover it."
