Figure 101.—Marasmius oreades. Two-thirds natural size.
Oreades, mountain nymphs. Pileus is fleshy, tough and pliable when moist, brittle when dry, convex, becoming flat, somewhat umbonate, brownish-buff at first, becoming cream-color; when old it is usually quite wrinkled.
The gills are broad and wide apart, creamy or yellowish, rounded at the stem end, unequal in length.
The stem is solid, equal, tough, fibrous, naked and smooth at base, everywhere with a downy surface. The spores are white, 8×5.
To my mind there is no more appetizing mushroom than the "Fairy Ring" mushroom. Figure 101 will give an accurate notion of the plant and Figure 102 will show how they grow in the grass. It is found in all parts of Ohio. Every old pasture field or lawn will be full of these rings. The plant is small but its plentifulness will make up for its size.
There are many conjectures why this and many other mushrooms grow in a circle. The explanation is quite obvious. The ring is started by a clump or an individual mushroom. The ground where the mushroom grew is rendered unfit for mushrooms again, the spores fall upon the ground and the mycelium spreads out from this point, consequently each year the ring is growing larger. Sometimes they appear only in a crescent form. One can tell, by looking over a lawn or pasture, where the rings are, because, from the decay of the mushroom, the grass is greener and more vigorous there.
Long ago, in England and Ireland, before the peasantry had begun to question the reality of the existence of the fairy folk and their beneficent interference in the affairs of life, these emerald-hued rings were firmly believed to be due to the fairy footsteps which nightly pressed their chosen haunts, and to mark the "little people's" favorite dancing ground. "They had always fine music among themselves, and danced in a moonshiny night around or in a ring, as one may see to this day upon every common in England where mushrooms grow," quaintly says one old writer. And the Rev. Gerard Smith still further voices the belief of the people as to the nature of these grassy rings:
"The nimble elves
That do by moonshine green sour ringlets make,
Whereof the ewe bites not; whose pastime 'tis
To make these midnight mushrooms."
