Agaricaceae 



Lactarius. Pa. Solitary and gregarious, moist woods and wooded places. July 

 to September. Mcllvaine. 



In my long experience with the plant I have not seen any change of 

 color, save that, like the white milk of other species, it darkens slightly 

 to a cream color. I have found it distinctly umbilicate and quite um- 

 bonate in the same patch. 



L. lignyotus is one of the best of Lactarii and quite equal to L. 

 volemus. 



L. COrru'gis Pk. having wrinkles or folds. Pileus 3~5 in. broad, 

 firm, convex, then nearly plane or centrally depressed, rugose reticulated, 

 covered with a velvety pruinosity or pubescence, dark reddish-brown or 

 cliestnut-color, fading with age to tawny-brown. Gills close, dark 

 cream-color or subcinnamon, becoming paler when old, sordid or brown- 

 ish where bruised or wounded. Stem 35 in. long, 612 lines thick, 

 equal, solid, glabrous or merely pruinose, paler than but similar in color 

 to the pileus. Spores subglobose, 1013^1. Milk copious, white, taste 

 mild. 



Thin woods. Sandlake, Gansevoort and Brewerton, N. Y. August 

 and September. 



This curious Lactarius is related to L. volemus, from which it may 

 be separated by its darker colors and its corrugated pileus. The flexu- 

 ous reticulated rugae present an appearance similar to that of the 

 hymenium of a Merulius. The pileus is everywhere pruinose-pubescent 

 and the gills bear numerous spine-like or acicular cystidia or spicules, 

 4 5/tx long. These are so numerous on and near the edges of the gills 

 that they give them a pubescent appearance. Peck, 38th Rep. N. Y. 

 State Bot. 



I found many at Mt. Gretna, Pa., up to 6K in. in diameter. Flesh 

 not so firm as L. volemus. Stem equal, rugulose, flattened in old 

 specimens. Milk very slightly acrid. 



Better in taste and quality than L. volemus. 



L. lute'olllS Pk. yellowish. PileilS 2-3 in. broad, fleshy, rather 

 thin, convex or nearly plane, commonly umbilicately depressed in the 

 center and somewhat rugulose, pruinose or subglabrous, buff-color. 

 Flesh white, taste mild. Milk copious, flowing easily, white or whitish. 

 Gills close, nearly plane, adnate or slightly rounded behind, whitish,
