Lentinus lepideus is a sort of commercial traveler. It is common wherever railroads are. It is partial to oak ties and its mycelium is injurious to them. It is found upon pine and other timbers. The writer has collected large clusters of it from oak sawdust. The European plant is noted as “almost always solitary.” In the United States it is seldom so. It is noted as growing in damp, dark places, but it loves the sun. As a food it is about on a par with P. ulmarius, not as tough, but harder when old. It is a reliable species from spring until late autumn, is persistent and dries well. It is neat, handsome, prolific. When young it makes a good dish, and when old can be used to advantage in soups. =L. cochlea´tus= Fr.—_cochlea_, a snail. =Pileus= 2–3 in. broad, flesh-color, but becoming pale, somewhat tan, fleshy-pliant, thin, commonly excentric, imbricated, very unequal, somewhat lobed or contorted, sometimes plane, sometimes funnel-shaped-umbilicate, but not pervious, _smooth_. =Stem= solid, firm, sometimes central, most frequently excentric, sometimes wholly lateral, _always sulcate, smooth_, flesh-colored upward, reddish-brown downward. =Gills= decurrent, crowded, serrated, white-flesh-color. _Fries._ Pliant, tough, flaccid, very changeable in form, sometimes solitary, sometimes cespitose, imbricated, growing into each other. From very small forms which are commonly solitary, with the stem and pileus scarcely 1 in. it ranges to 3 in. On stumps. Frequent. August to October. According to Fries the odor is weak, of anise; but it is generally strong and very pleasant. _Stevenson._ =Spores= nearly globular, 4µ diameter _Morgan_; spheroid or ellipsoid-spheroid, uniguttate, 4–6µ _K._; almost globular, 4µ _W.G.S._ The dense clusters of all sized members are usually plenty in favored localities. It is inviting in appearance, taste and spicy odor. It retains a suspicion of the latter when cooked which gives the dish a flavor pleasant to many. It must be young to be tender. When dry—like others of its kind—it can be grated and used in many ways. =L. Un´derwoodii= Pk. =Pileus= fleshy, tough, convex or nearly plane, the glabrous surface cracking into areola-like scales which are indistinct or wanting toward the margin, whitish or slightly tinged with buff or pale ochraceous. =Flesh= white. =Gills= moderately close, decurrent, slightly connecting or anastomosing at the base, somewhat notched on the edge, whitish, becoming discolored in drying. =Stem= stout, hard, solid, eccentric, squamose, colored like the pileus. =Spores= oblong, 13–15×5–6.5µ. =Plant= cespitose. =Pileus= 3–6 in. broad. =Stem= 1.5–3 in. long, about 1 in. thick. This differs from L. magnus in its cespitose habit, eccentric stem, longer spores, less distinctly areolate-squamose pileus and in its habitat. The gills are connected at the base very much like those of Pleurotus ostreatus. _Peck_, Torr. Bull. Vol. 23, No. 10. North Carolina, Pennsylvania, _McIlvaine_.
