=Lentinus lecomtei= Fr., is a very common and widely distributed species growing on wood. When it grows on the upper side of logs the pileus is sometimes regular and funnel-shaped (cyathiform), but it is often irregular and produced on one side, especially if it grows on the side of the substratum. In most cases, however, there is a funnel-shaped depression above the attachment of the stem. The =pileus= is tough, reddish or reddish brown or leather color, hairy or sometimes strigose, the margin incurved. The =stem= is usually short, hairy, or in age it may become more or less smooth. The =gills= are narrow, crowded, the spores small, ovate to elliptical 5--6 × 2--3 µ. According to Bresadola this is the same as _Panus rudis_ Fr. It resembles very closely also _Panus cyathiformis_ (Schaeff.) Fr., and _P. strigosus_ B. & C. =Lentinus lepideus= Fr., [_L. squamosus_ (Schaeff.) Schroet.] is another common and widely distributed species. It is much larger than _L. lecomtei_, whitish with coarse brown scales on the cap. It is 12--20 cm. high, and the cap is often as broad. The stem is 2--8 cm. long and 1--2 cm. in thickness. It grows on wood. [Illustration: FIGURE 132.--Lentinus vulpinus, front and under view (natural size). Copyright.] =Lentinus stipticus= (Bull.) Schroet. (_Panus stipticus_ Bull.) is a very small species compared with the three named above. It is, however, a very common and widely distributed one, growing on wood, and may be found the year around. The pileus is 1--3 cm. in diameter, whitish or grayish, very tough, expanded in wet weather, and curled up in dry weather. The stem is very short, and attached to one side of the cap. When freshly developed the plant is phosphorescent. SCHIZOPHYLLUM Fr. This is a very interesting genus, but the species are very few. The plants are tough, pliant when fresh, and dry. The gills are very characteristic, being split along the edge and generally strongly revolute, that is, the split edges curve around against the side of the gill. This character can be seen sometimes with the aid of a hand lens, but is very evident when a section of the cap and gills is made and then examined with a microscope. The spores are white.
