Lactaria sordida Peck, Ann. Rep. N. Y. State Cab. 23: 119. 1872. 
Pileus fleshy, thick, convex-umbilicate, then plane to depressed in the center, 6-12 cm. 
broad; surface yellowish-brown or umber, with olivaceous tinge, darker in the center, 
azonate, slimy-viscid in wet weather, glabrous or agglutinated-fibrous ; margin involute at 
first and yellow-villose, then glabrous: context firm, whitish, with slight odor; latex white, 
unchanging, acrid; lamellae cream-colored, then darker yellow, becoming nearly black 
where bruised, then ash-colored from the spores, many forking near the stem, close, some- 
what decurrent, 3-4 mm. broad; stipe of the same color as the pileus, equal or slightly 
smaller at the base, viscid when wet, glabrous, smooth or somewhat scrobiculate, or some- 
times merely spotted, firm, stuffed, occasionally becoming hollow when old, usually 34 
cm. long, 1.5-2.5 cm. thick: spores white, globose to subglobose, echinulate, 6.5-8 4 in 
diameter.

surface from yellowish-white to dull-yellow, zonate or azonate, viscid when young or wet, 
covered with rather long yellowish tomentum : context firm, thick ; latex white, becoming

in concentric lines corresponding to the zones; margin involute at first, at length spread- 
ing, tomentose : context firm, white, odorless; latex white, staining the flesh and lamellae 
heliotrope, mild to slightly acrid, abundant in young plants, scanty in old ones; lamellae 
white, becoming pale maize-yellow and pruinose with age, staining heliotrope where injured,
