19 IS] The Lactakias of JSTorth Carolina 57 



Gills very distant, some short marginal ones and a few branched 

 near the stem, about 4-5 mm. wide, very thick, firm and tough, nar- 

 rowly attached, not decurrent, not brown when bruised. 



Stem 3 cm. long, 11 mm. thick at top, tapering downward, light 

 and smooth above, somewhat scurfy cracked like the cap margin 

 below and of the same color, texture quite firm, tough and solid. 



Spores pure white, broad elliptic, minutelv warted under hidi 

 power, 3.7-4.8 x 5.5-7 Afi. 



This is evidently in the Lactiflua group, but differs from related 

 species in the very tough and tenacious texture of all parts, the quite 

 different spores, which are much smaller and smoother than in L. liy- 

 grophoroides B. & C. as it is represented in Chapel Hill and in Miss 

 Burlingham's exsiccati.

We have not recognized this species at Chapel Hill, but it has been 

 reported from North Carolina, and we include the following descrip- 

 tion, adapted from Miss Burlingham (Mem. Torr. Bot. Club 14:98. 

 1908): 



"Pileus fleshy, firm, rather thin, convex, often umbonate, at length 

 expanded, depressed in the center, but the margin still arching, ful- 

 vous (308) to madder-brown (334), azonate, dry, glabrous, 1-4 em. 

 1)road, margin inrolled and pruinose at first, not striate; gills whitish 

 or flesh-colored (G7), becoming reddish-brown, sometimes a few fork- 

 ing next the stem, close, adnate to slightly decurrent, rather narrow; 

 stem of the same color as the pileus or paler, nearly equal, sometimes 

 flexuous, glabrous, pruinose, smooth, fii-m to sjiougy, 1-3 cm. long, 

 3-8 mm. thick ; flesh of about the color of the gills, unchanging, odor 

 aromatic, becoming more pronounced in drying; spores white, glo- 

 bose, echinulate, G-7/^; latex white, unchanging, niihl, abundant.
