Clavarias of the United States and Canada 29 



almost pseudo-parenchymatous in transverse section, even when 

 old; cells regular, 10-14(x in diameter, with small narrow filaments 

 (4-5jjl in diameter) between; segments 50-70[/. long towards the 

 margin, but up to 200-300[x in the center. Basidia conspicuous, 

 about 70\l long, contents granular, sterigmata 4. Spores smooth, 

 hyaline, cylindric to elliptic with a minute lateral basal apiculus, 

 10-11 x 5-6[/. (or sometimes 10-14 x 6-7f/.), contents granular. 

 "Habitat. In heathy places. Not uncommon." 



Peck describes C. pallescens as follows (adapted) : 



Club simple, loosely cespitose or sometimes gregarious, about 

 1 inch tall, clavate, obtuse, generally terete, soft, fragile, stuffed 

 or hollow, pale buff fading to whitish, more persistent lemon-yel- 

 low within ; stem distinct, short, glabrous, 2-4 mm. long, pale yel- 

 low ; spores white, oblong or ellipsoid, 6.3-7 x 8.9-12. 7\x. [We find 

 them to be rod-elliptic with a small eccentric mucro, 4.2-5.4 x 9.3- 

 12.2[x]. Dry gravelly soil near clumps of lambkill, Kalmia angus- 

 ti folia L., South Acton, Mass., October. 



Peck adds that the species is allied to C. ligula, but in this he 

 seems to be wrong. A cespitose habit is not mentioned by Cotton 

 and Wakefield, but among the examples sent us by the latter are 

 several close groups of three or four. The obtuse, club-shaped 

 form is a marked character of the species. In the dried state the 

 plants are spatulate and taper downward from a broad tip. 



Patouillard's idea of the species seems to agree very well with 

 the above, except that his fig. 587 shows the spores as pip-shaped. 

 He describes the plant (Tab. Fung., p. 34) as fascicled, obtuse, 

 attenuated at the base, cylindrical, pale clay color. Spores ovoid, 

 8 x 5(jl; basidia 4-spored. He recognizes as distinct both C. cricc- 

 torum and C. flavipes. For the former he shows compressed, 

 twisted plants forked at tip, two touching at base, about 12.5 cm. 

 high; spores 10x5[x (fig. 585). For the latter he shows (fig. 

 586) simple clubs, scattered or fascicled, cylindrical or flattened, 

 attenuated to a "citron yellow stalk." Spores ovoid or subglo- 

 bose (no dimensions given) ; basidia 4-spored. The stalk does 

 not appear distinct. 



Clavaria obtusata as represented in the herbarium of the Uni- 

 versity of Paris (Savigne, November, 1913) is to all appearances
