1918^ The Lactaeias of North Carolina 17 



changing or (in a Chapel Hill form) turning when cut (if not too 

 old) to light pink with or without a light tint of lavender ; odor very 

 slight, pleasant. Milk abundant, light creamy white, not changing, 

 very acrid, but not otherwise disagreeable. 



Gills crowded, narrow, only 3-4 mm. wide, nearly equal, the whole 

 wavy, attached, some forking at the stem, nearly white, then creamy, 

 then maize yellow with a distinct flesh tint, turning sordid brown 

 when bruised. 



Stem short, stout, 2.5-3 cm. long, and 1.6-2.2 cm. thick, usually 

 equal, minutely pruinose-felted or somewhat smoothish, nearly white 

 with more or less distinct yellowish scrobiculate spots, and sometimes 

 with lavender-pink tints, firm and brittle, becoming hollow, the flesh 

 at times becoming pink when cut. 



Spores yellowish, elliptic, strongly tuberculate, 5.5-7.4 x 7.4-9. 2/i. 



Easily recognized by the large size, felted margin, and unchanging- 

 acrid milk. Distinguished from L. cilicioides by zoned cap with 

 center smooth and less bright color of the gills when dry. It is poi- 

 sonous, but the poison is said to disappear on cooking (Ford. Jour. 

 Phar. and Exp. Ther. 2:21)6. 1911). The species is described as 

 having unchanging flesh, and this was true of our No. 764. In Nos. 

 2361 and 2393, on the other hand, the flesh turned pinkish when cut, 

 though in other respects the plants were just like the typical form. 

 The colored figure, given in Mycologia 8: PI. 87. 1916, would give a 

 very misleading idea of our plant. Dried plants of this species at 

 the New York Botanical Gardens appear exactly like ours. 



764. Woods near Battle's Brook, Chapel Hill, September 14, 1913. Milk 

 white, unchanging, decidedly acrid; pock-marks on stem, small and 

 faint; no forked gills; flesh and gills not turning lilac or pink when 

 cut or bruished; spores warted and ridged, 6.6-7.5x7.5-8.5^. This is 

 typical L. torminosus.

 No. 2361. representing numerous plants, the flesh turned light pink 

 when cut.
