Clavarias of the United States and Canada 53 



Illustration: Burt. Ann. Mo. Bot. Gard. 9: pi. 8, fig. 72 (as C. nebulosa). 

 1922. 



North Carolina: Camp Bragg. J. S. Holmes. (U. N. C. Herb.). No. 

 4860. On coarse sandy soil in pine forest in opening made by a dead 

 pine, April 14, 1921. 



Colorado: Dark Canyon. Clements. (N. Y. Bot. Gard. Herb.). Spores 

 3 x 8-9/x. These are labelled C. purpurea, but they are doubtfully that 

 species. A photograph accompanying the plants looks exactly like C. 

 fumosa and the spores are scarcely larger than the upper limit in that 

 species. 



Newfoundland: Sandy Point. Waghorne. (Albany Herb., as type of C. 

 nebulosa; also plants from the type locality in N. Y. Bot. Gard. Herb.). 



New Brunswick : Miss Home. (Albany Herb.). 



Utah: Uinta Mtns., alt. 10,000 ft. Watson. (N. Y. Bot. Gard. Herb.). 

 Spores about 3.5-4 x 8.5-9/x. 



Clavaria appalachiensis n. sp. 



Plates 10 and 91 



Plants simple, single or rarely cespitose in groups of 2-4, gre- 

 garious in small numbers ; height 3-9 cm., the stem very distinct 

 and sharply defined, 1-4 cm. long, terete, smooth and shining, 

 lemon yellow except for the whitened and subtomentose base. 

 Club 2-6 cm. long, 1.5-5 mm. thick, straight or bent, equal, terete 

 or less often compressed, delicately but very distinctly and regu- 

 larly ridged and furrowed longitudinally (as in C. nigrita) ; color 

 varying from pale fleshy yellow to light cream or creamy yellow, 

 the rounded tips concolorous, then fading brownish. Flesh of 

 club concolorous, very tender and brittle, snapping clean at an angle 

 of 45°, solid but usually soon hollowed by grubs; stem tough and 

 pliable, not breaking when bent on self, with a cartilaginous rind 

 and softer center. Taste and odor none. 



Spores (of No. 5650, type) white, smooth, subspherical, 

 4.8-6.5 x 5.5-7.2|i, with a large oil drop and a distinct mucro. Ba- 

 sidia 4-spored or (a few) 2-spored, 7.3-8. 5fi. thick. Threads of 

 flesh parallel, about 4.8[x thick under the hymenium, larger to- 

 wards the center, where they are about 14^ thick on an average. 



We have found the species only in frondose woods on very 

 rotten deciduous logs (probably chestnut) or on pure leaf mold and 

 at an elevation of about 4000 feet. Known at present only from 

 North Carolina and Pennsylvania. It is a well marked plant and
