1918} The Lactaeias of North Caeolixa 53 



"Distinguishing Field-Maeks : This species is closely related 

 to Lactaria ligniota Ft., but can be distinguished from it by the white 

 spores, the unchanging color of the broken flesh or gills, and the more 

 distant gills."

Cap generally more or less infundibuliform with various irregu- 

 larities of the edges, surface smooth, not velvety, often with decided 

 corrtigations, particularly near the edge, and not rarely with cracks on 

 the margin, color brownish-orange, or a much deeper browmish-red 

 (Sanford's brown or cinnamon-rufous, Ridgway), sometimes very 

 much lighter, not darker than light cream color. Flesh firm, white 

 at first, changing when cut to a brownish-red. Milk very abundant, 

 sticky, mild, white, and remaining white. 



Gills at first creamy-white, turning a pretty creamy-yellow, and 

 when bruised a dark, sordid brown, about 4-5 mm. wide, pointed at 

 the stem, more or less decurrent, varying greatly in number, and so 

 quite crowded or decidedly distant. 



Stem 1.5-5 cm., usually 3-4 cm., long and about 1 cm. thick, very 

 irregular, stuffed, surface pruinose except at base, where it is finely 

 white velvety, colored about like the cap and lightest at the top. 



Spores (of No. 104) white, globular, warted, 7.4-8. 2m in diameter. 



This plant is nearest L. corrugis, but has not the fine tomentum of 

 that species or the deeply colored gills when young. It is a good- 

 sized, attractive, and rather common plant that is recorded among tlie 

 best to eat. For an illustration in color see N, Y. St. ^In. Ko]t. 48:
