yellow color deepening upward. Flesh not very brittle and thus differ- 

 ing distinctly from C. flava as well as in color and other ways. These 

 had faded when found to a pinkish cinnamon upwards. Spores nearly 

 smooth, 3.1-3.6x6.6-8/*. 



New York: Lake George. Coker, Nos. 13 and 14. (U. N. C. Herb.). In 

 oak and maple woods, Prospect Mountain trail, September 3, 1917. 

 Color deep chrome yellow above, shading to a clearer yellow in middle 

 and white at the pointed base ; very delicate, divaricating ; flesh yellow,

Clavaria flava var. subtilis n. var. 



Plate 85 



A clear rather pale yellow upward (near apricot yellow), pale 

 fleshy cream elsewhere except the white, glabrous base, which 

 tapers to a point; in most cases distinctly rugose upwards; odor 

 very slight. When dry hard and not chalky or very fragile. 



Spores (of No. 2843) elliptic, distinctly rough, but not so 

 much so as in C. formosa, 4-4.5 x 10-lljx. Basidia 4-spored, about 

 9(j. thick. Hymenium 55-7CV thick; basidia 7.4-8.% thick with 4 

 long, straight sterigmata. Hyphae of flesh about 7.5-1 If/, thick, 

 nearly parallel, not densely packed. 



Differs from C. formosa in the texture when dry, which is 

 not chalky or very fragile, in absence of bitter taste when dry, in 

 decidedly thicker and nearly parallel hyphae, and in more nar- 

 row and less rough spores. Differs from C. flava var. aurea 

 (No. 2893) in thicker hymenium, thicker basidia and larger and 

 rougher spores. Differs from C. subbotrytis (No. 2847) as fol- 

 lows: less brittle; much less flesh color and more yellow; base 

 more slender ; flesh nearly or quite white ; taste mildly acid-bitter 

 (C. subbotrytis is nearly tasteless). The flesh is dry and fibrous 

 and softer than in the firmer, more brittle and less fibrous C. 

 botrytis, C. flava and C. subbotrytis.
