Clavarias of the United States and Canada 21 



22[l. Hymenium about 35[x thick, densely set with large and small 

 crystals; threads of flesh variable in diameter, up to 9^ thick, 

 closely packed, parallel in longitudinal section, clamp connections 

 present. 



On comparison of the type of C. filipes at Kew, we have no 

 doubt our plants are the same. There are three plants preserved 

 in good condition, all with long, slender stalks very distinct from 

 the club and the little mycelial boot is obvious; spores few but 

 apparently similar, 3.7-4.2 x 5.5-7 Ay.. The original description 

 (adapted) is: Pale rufous; stem filiform, distinct, fistulose, about 

 one inch long, springing from a white mycelium ; club long, cylin- 

 dric, curved, about as long as the stem. On the ground, South 

 Carolina, Ravenel, No. 1488. [The words "pale rufous" almost 

 certainly refer to the dried plants. ] 



The types of C. tenuipes B. & Br. at Kew are unlike our 

 plants and are certainly a different species (see Cotton and 

 Wakefield in Trans. Brit. Myc. Soc. 6: 186. 1919). 



From solitary plants of C. fragilis and C. helveola the present 

 species is distinguished by the longer, tougher, and more distinct 

 stem, the different spores, and the usually different color.

 glabrous except for the faintly fibrous base, pale yellow to pale 

 lemon yellow, varying in some of the younger or more delicate to 

 translucent white. Club cylindric, often curved, 0.7-2.6 mm. 

 thick, terete or compressed, not rugose, pale creamy white in 

 youth, becoming slightly more yellowish, some with a faint wine 

 tint above, drying dull ochraceous or buff; tips rounded, concol-
