The =pileus= is fleshy, thick, firm, convex, umbilicate, and then depressed in the center, becoming finally more or less funnel-shaped by the elevation of the margin. It is white, smooth when young, in age sometimes becoming sordid and somewhat roughened. The =gills= are white, very narrow, very much crowded, and some of them forked, arcuate and then ascending because of the funnel-shaped pileus. The =spores= are _smooth_, oval, with a small point, 5--7 × 4--5 µ. The =stem= is equal or tapering below, short, solid. The milk is white, unchangeable, very acrid to the taste and abundant. The plant is reported as edible. A closely related species is _L. pergamenus_ (Swartz) Fr., which resembles it very closely, but has a longer, stuffed stem, and thinner, more pliant pileus, which is more frequently irregular and eccentric, and not at first umbilicate. Figure 122 is from plants (No. 3887, C. U. herbarium) collected at Blowing Rock, N. C., during September, 1899. [Illustration: FIGURE 123.--Lactarius resimus. Entire plant white, in age scales on cap dull ochraceous (natural size). Copyright.] =Lactarius resimus= Fr.?--This plant is very common in the woods bordering a sphagnum moor at Malloryville, N. Y., ten miles from Ithaca, during July to September. I have found it at this place every summer for the past three years. It occurs also in the woods of the damp ravines in the vicinity of Ithaca. It was also abundant in the Blue Ridge Mountains of North Carolina, during September, 1899. The plants are large, the caps 10--15 cm. broad, the stem 5--8 cm. long, and 2--3 cm. in thickness. The =pileus= is convex, umbilicate, then depressed and more or less funnel-shaped in age, white, in the center roughened with fibrous scales as the plant ages, the scales becoming quite stout in old plants. The scales are tinged with dull ochraceous or are light brownish in the older plants. The ochre colored scales are sometimes evident over the entire cap, even in young plants. In young plants the margin is strongly involute or inrolled, and a loose but thick veil of interwoven threads extends from the surface of the roll to the stem. This disappears as the margin of the cap unrolls with the expanding pileus. The margin of the pileus is often sterile, that is, it extends beyond the ends of the gills. The =gills= are white, stout, and broad, decurrent, some of them forked near the stem. When bruised, the gills after several hours become ochraceous brown. The spores are subglobose, minutely spiny, 8--12 µ. The =stem= is solid, cylindrical, minutely tomentose, spongy within when old. [Illustration: FIGURE 124.--Lactarius resimus.
