=Entoloma strictius= Pk.--The plants grow in grassy places, pastures, etc. They are clustered, sometimes two or three joined at the base of the stem. They are 7--10 cm. high, the caps 2--4 cm. broad, and the stems 3--6 mm. in thickness. The =pileus= is convex, the disk expanded, and the margin incurved and more or less wavy or repand on the extreme edge. It is umbonate at the center with usually a slight depression around the umbo, smooth, watery (hygrophanous) in appearance, not viscid, of an umber color, shining, faintly and closely striate on the margin. In drying the surface of the pileus loses some of its dark umber color and presents a silvery sheen. The flesh is fibrous and umber color also. The =gills= are grayish white, then tinged with flesh color, slightly sinuate, the longer ones somewhat broader in the middle (ventricose), rather distant, and quite thick as seen in cross section, the center of the gill (trama) presenting parallel threads. The sub-hymenium is very thin and composed of small cells; the =basidia= are clavate, 25--30 × 9--10 µ, and four-spored. The =spores= are dull rose color on paper, subgloblose, 5--8 µ in diameter, angular with 5--6 angles as seen from one side. The =stem= is the same color as the pileus, but considerably lighter. It is hollow with white fibers within, fibrous striate on the surface, twisted, brittle, and somewhat cartilaginous, partly snapping, but holding by fibers in places, cylindrical, even, ascending, with delicate white fibers covering the lower end. [Illustration: FIGURE 141.--Entoloma strictius. Cap umber or smoky, stem paler, gills grayish, then flesh color (natural size). Copyright.] Figure 141 is from plants (No. 2461, C. U. herbarium) collected near Ithaca, October, 1898. LEPTONIA Fr. In _Leptonia_ the stem is cartilaginous, hollow or stuffed, smooth and somewhat shining. The pileus is thin, umbilicate or with the center darker, the surface hairy or scaly, and the margin at first incurved. The gills are adnate or adnexed at first, and easily separating from the stem in age. Many of the species are bright colored. [Illustration: FIGURE 142.--Leptonia asprella. Cap hair brown (mouse colored), minute dark scales at center, stem same color, but sometimes reddish brown, green or blue, gills flesh color.] =Leptonia asprella= Fr.--This species occurs on the ground in woods or in open grassy places. The plants are 3--5 cm. high, the cap 2--4 cm. broad, and the stem 2--3 mm. in thickness. The =pileus= is convex, then more or less expanded, umbilicate, rarely umbonate, hair brown (mouse colored), with dark scales on the center and minute scales over the surface, striate. The =gills= are sinuate to adnexed. The =spores= are strongly 5--6 angled, 10--12 × 8--10 µ. The =stem= is smooth, even, usually the same color as the cap, but sometimes it is reddish brown, green, or blue. Figure 142 is from plants (No. 3996, C. U. herbarium) collected at Blowing Rock, N. C., during September, 1899.
