Pleurotus salignus. Fr.

The Willow Pleurotus. Edible.

Salignus, from salix, a willow. Pileus is compact, nearly halved, horizontal, at first cushion-shaped, even, then with the disk depressed, substrigose, white or fuliginous. The stem, eccentric or lateral, sometimes obsolete, short, white-tomentose. The gills are decurrent, somewhat branched, eroded, distinct at the base, nearly of the same color. Spores .00036 by .00015 inch. Fries.

I found this species near Bowling Green on willow stumps. About every ten days the stumps offered me a very excellent dish, better than any meat market could afford. September to November.

Pleurotus ulmarius. Bull.

The Elm Pleurotus. Edible.

Figure 119.—Pleurotus ulmarius. One-third natural size.

Ulmarius, from ulmus, an elm. It takes its name from its habit of growing on elm trees and logs. It appears in the fall and may be found in company with the Oyster mushroom, late in December, frozen solid. This species is frequently seen on elm trees, both dead and alive, on live trees where they have been trimmed or injured in some way. It is often seen on elms in the cities, where the elm is a common shade tree. Its cap is large, thick and firm, smooth and broadly convex, sometimes pale yellow or buff. Frequently the epidermis in the center of the cap cracks, giving the surface a tessellated appearance as in Figure 119. The flesh is very white and quite compact. The gills are white or often becoming tawny at maturity, broad, rounded or notched, not closely placed, sometimes nearly decurrent. The stem is firm and solid, various in length, occasionally very short, inclined to be thick at the base and curved so that the plant will be upright, as will be seen in Figure 119.
