Agaricaceee 



Eussuia. West Virginia. 1882; Pennsylvania, 1887-1894; New Jersey, 1892. 

 Solitary in pine and hemlock woods, generally on bare, compact ground. 

 August to October. Mcllvaine. 



This species is a sparse grower, but its good size and respectable num- 

 bers soon fill the basket. When fresh it is of good substance and flavor. 



K. del'ica Fr. deliciis, weaned. (Milkless, juiceless in gills.) 

 White. Pileus 3-5 in. broad, fleshy throughout, firm, umbilicate then 

 infundibuliform, regular, everywhere even, smooth with a whitish luster, 

 the involute margin without striae. Flesh firm, juiceless, not very 

 thick, white. Stem curt, 1-2 in. long, %. in. and more thick, solid, 

 even, smooth, white. Gills decurrent, thin, distant, very unequal, 

 white, exuding small watery drops in wet weather. Fries. 



Spores minutely echinulate, white, broadly elliptical, 8-iox6-7/A 

 Mas see. 



In appearance it resembles Lactarius vellereus and L. piperatus, but 

 its gills do not distill milk or juice. It differs, too, in its mild taste. It 

 is related to R. brevipes Pk. 



A large, coarse species, cup-shaped at maturity. I have found it in 

 several localities in Massachusetts in July and August. It is of fair 

 quality cooked, but much inferior to R. virescens, etc. Macadam. 



West Virginia, Pennsylvania, New Jersey, in mixed woods, August 

 to October. Mcllvaine. 



Edible. Taste mild. From the juiceless variety of L. vellereus its 

 mild taste alone furnishes a separate character. Peck. 



I have eaten it since 1882, but it is not a favorite. Its quality is fair. 



R. sor'dida Pk. dirty. (Plate XLIV, fig. 4, P . 184.) Pileus firm, 

 convex, centrally depressed, dry, sordid-white, sometimes clouded with 

 brown. Gills close, white, some of them forked. Stem equal, solid, 

 concolorous. Spores globose, 7- 5/*' Taste acrid. Flesh changing color 

 when wounded, becoming black or bluish-black. 



Plant 4-5 in. high. Pileus 3-5 in. broad. Stem 6-12 lines thick. 



Ground under hemlock trees. Worcester. July. 



It resembles L. piperatus in general appearance. The whole plant 

 turns black in drying. Peck, 26th Rep. N. Y. State Bot.
