130 Thiety-eighth Report ox the State Museum. 



pubescence or tomentum, dry, sometimes rugose-wrinkled and often 

 becoming rimose-areolate, yellowish-tawny or brownish-orange; lamellae 

 distant, adnate or subdecurrent, white or cream-color, the interspaces 

 uneven or venose; stem short, equal or tapering downward, solid, glabrous 

 or merely pruinose, colored like the pileus ; spores subglobose or broadly 

 elliptical, nearly smooth, .00035 t0 - 000 45 m -> milk white, taste mild. 



Pileus 1 to 4 in. broad, stem .5 to 1 in. long, 4 to 8 lines thick. 



Grassy ground and borders of woods. Albany, Greenbush and Sand- 

 lake. July and August. 



This plant has almost exactly the color of L. volemus, but differs 

 from it in its distant lamellae, short stem, less copious milk and less 

 globose spores. Its flesh is white, with a thickness about e^ual to the 

 breadth of the lamellae. It is probably edible, but has not yet been 

 tested. The typical L. hygrophoroides is described as havitg the pileus 

 yellowish-red and pulverulent, and the lamellae luteous. It is also repre- 

 sented as a small plant; but our specimens, while not fully agreeing 

 with this description, approach so closely to it in some of their forms 

 that they doubtless belong to the same species. We have therefore 

 extended the description so that it may include our plant. In wet 

 weather the pileus sometimes becomes funnel-form by the elevation of 

 the margin. 



Lactarius volemus, Fr. 



Orange Lactarius. Orange-brown Lactarius. 

 Agaricus testaceus, A. & S. A. ruber, Seer. 



Pileus firm, convex nearly plane or centrally depressed, rarely inf un- 

 dibuliform, sometimes with a small umbo, generally even, glabrous, dry, 

 golden-tawny or brownish-orange, sometimes darker in the center, often 

 becoming rimose-areolate ; lamellae close, adnate or subdecurrent, white 

 or yellowish, becoming sordid or brownish where bruised or wounded ; 

 stem subequal, variable in length, firm, solid, glabrous or merely prui- 

 nose, colored like the pileus, sometimes a little paler ; spores globose, 

 white, .00035 to .00045 m '1 milk copious, white, taste acrid. 



Var. subrugosus. Pileus rugose-reticulated on the margin. 



Pileus 2 to 5 in. broad, stem 1 to 4 in. long, 4 to 10 lines thick. 



Thin woods and open places. Common. July to September. Edible. 



The color of the pileus is a peculiar mixture of red and yellow, some- 

 times shaded with brown. It is generally free from the attacks of in- 

 sects, and this, with its beautiful and nearly uniform color 2 makes it an 

 attractive species. It is nearly as celebrated as L. deliciosiis for its edi- 

 ble qualities. Cordier says " it is one of the most agreeable fungi to 

 eat." Its flesh is firm but brittle, white or yellowish. Its milk is very 

 abundant and its taste mild or slightly astringent. In drying, the speci- 

 mens sometimes emit a disagreeable odor. We have followed Fries and 

 other continental mycologists in writing the specific name " volemus." 

 Some English authors have it "volemum." The variety connects this 

 species with the next. 



Lactarius corrugis. Peck. 

 Corrugated Lactarius. 

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

 reticulated, covered with a velvety pruinosity or pubescence, dark
