24. Lactarius delicatus Burl. 



This species is known only from Mount Pisgali, Xorth Carolina, 

 and the following is taken from Miss Burlingham's original descrip- 

 tion (Mem. Torr. B. C. 14:40, fig. 4. 1908) : 



"Pileus fleshy, firm, convex, umbilicate, at length nearly infundi- 

 buliform, maize-yellow (36 t. 3), tinted in the center with yellowish- 

 salmon (65), faintly but decidedly zonate, viscid and covered with 

 gluten when wet, glabrous, 8-12 cm. broad, margin involute at first 

 and covered with coarse short tomentum, then merely deflexed and 

 glabrous ; gills whitish, becoming maize-yellow with age, some forking 

 near the stem, close, slightly decurrent, 5-7 mm. broad ; stem whitish 

 to maize-yellow tinted wdth yellowish salmon, more or less scrobicu- 

 late-spotted, spots of the same color as the rest of the stem or duller, 

 equal or tapering downwards, glabrous, stuffed, becoming hollow, 

 4-5 cm. long, 1.5-2.5 cm. thick; flesh white, odor strong; spores tinted 

 yellowish-salmon in mass, subglobose, echinulate, 7-8m; latex white, 

 becoming sulphur-yellow, acrid, scanty. 



"Hab. : In sandy loam and dense shade, oak and chestnut woods. 

 July and August. 



"Distinguishing Field-Marks : The large size, the delicate yel- 

 lowish-salmon tint over nearly the whole pileus, the faint nearly con- 

 colorous zones, the short tomentum on the margin of the immature 

 pileus, the rather persistent viscidity, the lily shape of the mature 

 pileus, and the change in the color of the latex."

Plate 22. 



A good-sized plant that is not rare with us in pine woods in fall. 

 It varies considerably in color, but is marked by such distinctive 

 characters as to be easilv recoaiiized. 



Cap up to about 11 cm. broad, deeply depressed in center at ma- 

 turity and striate on the very margin, or not striate until old, surface 

 slightly viscid, smooth, but showing inherent fibers, sometimes not
