Plate 40. 



Cap 6.3 cm. broad, depressed in center, the margin rounded and 

 revoiute until full maturity, quite smooth all over and decidedly 

 viscid, when wet faintly many zonate, the zones not conspicuously 

 spotted; color a rather light orange yellow. Flesh firm, rather brit- 

 tle, about 6 mm. thick near stem and turning slowly to reddish yellow 

 when wounded. Milk quite sparse, very acrid, most so after several 

 minutes, white, its change of color not noticeable at once, but after a 

 time the cut surfaces become a deep reddish yellow. 



Gills moderately distant, a few forked or anastomosing, about 

 5.5 mm. wide beyond the middle, rounded at stem and attached, 

 color creamy on side view, deeper on edge view, turning deep reddish 

 yellow when bruished. 



Stem 3.5 cm. long, 14 mm. thick at top, tapering downward, 

 smooth, lighter than cap, a few scrobiculatc spots which in this case 

 were not deeper colored, surface becoming darker when handled; 

 flesh firm, stuffed. 



Spores light ocliraceous, short-elliptic, tuberculate, 5. 5-6.2x7. 5-8. 2fi. 



This species may be distinguished from L. clirysurheus by the dis- 

 tant gills, darker and more viscid cap, and absence of fishy taste ; from 

 L. theiogalus by the much more acrid taste, distant gills, etc. It was 

 found by IMiss Burlingham in the Pink Bed Valley, North Carolina 

 (elevation about 1,000 meters). For nn illustration of the species 

 see Mem. T. B. C. 14: fig. 3. 1908.
