Agaricus Procerus.
Hygrometric properties
This species is especially free from the swarming grubs too commonly found in mushrooms. It is highly hygrometric, dries naturally even while standing in the pasture, in which condition it is decidedly aromatic in fragrance and nutty sweet to the taste, as described. Indeed, it is sometimes called "the nut mushroom." Absorbing moisture from the dews and rains, it again becomes pulpy and enlarged, thus alternating for days between its juicy and dry condition, in which latter state it may be gathered and kept for winter use. It is a palatable morsel at all times, but especially in the prime of its first expansion, each successive alternation, with its gradual loss of spores, affecting its full flavor.
THE RUSSULA GROUP
Generic characters
Among the wild species of mushrooms which the novice might possibly mistake for the common "mushroom" of the markets—which is popularly supposed to be the only edible variety, as distinguished from "toadstools"—is the Russula group. They are extremely frequent in our woods from spring to late autumn, and have many features in common. Their caps vary in color from a gray-green, suggesting cheese-mould, to olive-red, scarlet-red, and purplish. The gills are generally of the same length, or practically so, occasionally double-branched, beginning at the stem and usually extending to the rim of the cap, at which portion they are covered by the mere skin of the pileus, a slightly fluted appearance being observable from above, which indicates the location of the radiating laminæ below (Plate 12, fig. 6).
The stem may be white or cream-colored, or perhaps stained or mottled with the color of the cap.
