170 Clavarias of the United States and Canada 



rather numerous and crowded, the numerous tips pointed and 

 upright, or at times open and spreading; color when young 

 whitish, then delicate flesh color towards maturity with the tips 

 remaining white, the base shading to pale ochraceous; in drying 

 becoming pallid burl. Flesh delicate, but not very brittle, not 

 changing color when bruised; odor distinct, a rather medicinal 

 fragrance, lost on drying ; taste none. 



Spores (of C. & B. No. 107) rather light yellowish ochraceous, 

 much lighter than in C. abietina, varying from smooth to very 

 minutely rough, 3-3.3 x 4.8-6;/.. Basidia 4.4-5. 5[a thick, 4-spored; 

 hymenium 40-5 5 y. thick ; threads of flesh very variable in diameter, 

 up to 8[x thick. Just under the hymenium the threads are parallel 

 and fairly regular, but in the center of the plant they are very 

 irregular and much intertwined. The walls of the hyphae vary 

 from thin to thicker than the diameter of the space inside them, 

 the hymenium arising from the thin-walled threads; clamp con- 

 nections present. 



Not rare among rotting leaves and twigs under pine in the 

 northern states and in the mountains of North Carolina and col- 

 lected several times in Chapel Hill ; also found in Dismal Swamp, 

 Va., under junipers {Chamaecyparis). Easily distinguished from 

 all others by the combined characters of color, odor, spores, and 

 place of growth. 



The determination of this species is fortunately made certain 

 by the presence of a good plant of the type in Persoon's herbarium. 

 The appearance and the characteristic spores which are very 

 minutely rough, oval, 3-3.6 x 5-6[x, are conclusive. Persoon's 

 original description also agrees perfectly, and our plants are evi- 

 dently the same as those interpreted as C. gracilis by Karsten who 

 says they are slightly fragrant, with elliptic, ochraceous spores 

 3 x 5-6a ( Bidr. Finl. Nat. Folk 37 : 188. 1882). Fries says that the 

 plant has a slight anise odor, and our plants from Chapel Hill had 

 this fragrance to a distinct though faint degree. 



A plant from Bresadola in the New York Botanical Garden 



Herbarium, labelled C. gracilis, looks in the dried state like the 



plant we are calling C. Kunzei, and has the same minute spores ; 



other collections in the Bresadola Herbarium at Stockholm labelled 



„ Cijjracilis are also C. Kunzei, as one from Atkinson with asperu-
