Clavarias of the United States and Canada 23 



New York: Ithaca, etc. (Cornell Herb.). 



Long Island. Cold Spring Harbor, October 27, 1912. Harper. (N. Y. 

 Bot. Card. Herb., as C. vermicitlata). "Nearly white, solitary, obtuse, 

 4.5 cm. high." We find the spores to be smooth, elliptic, about 5 x 10.5p 



Clavaria gracillima Pk. Rept. N. Y. St. Mus. 28: 53, pi. 1, fig. 

 9. 1876. (NotC. gracillima Wakker. De Ziekten van het 

 Suikerriet op Java, p. 195. 1898.)

Peck's description follows: 



"Simple, very slender, smooth, about V high, rather tough; 

 club acute or acuminate, pale yellow, a little thicker than the long 

 slender distinct bright yellow shining stem. 



"In this species, as in C. argillacea, the hymenium is quite dis- 

 tinct from the stem." 



The types at Albany look exactly like C. subfalcata in general 

 appearance, size, etc., but we find the spores to be distinctly nar- 

 rower and of somewhat different shape from the latter. They 

 are smooth, subelliptic to pip-shaped, with somewhat curved 

 apical mucro, 3.6-4 x 7.4-lOf/.. The basidia are club-shaped, 

 4-spored, about 6 x 30\x. While this difference does not seem 

 great, it has proved consistent in all collections of C. subfalcata 

 examined, and we therefore hesitate to combine them. It would 

 probably be best to consider the difference only varietal.

New York: Northville. Among moss in a pasture. (Albany Herb., type). 



Clavaria fuscata Oud. Arch. Neerl. 2: 35, pi. 1, fig. 1. 1867. 

 C. foetida Atk. Ann. Myc. 6 : 56. 1908. 



Plate 81 



Plant 1.5-2.1 cm. high (up to 6 cm. in C. foetida), the color- 

 less, translucent stalk as long as or longer than the opaque white 

 or pale yellow, blunt club, with which it contrasts strongly but 

 into which it fades gradually. Stalk about 0.9 mm. thick; club 

 1.4 mm. thick, larger and more yellowish upward. Base of stem 

 smooth but springing from a more or less obvious mycelial film. 

 Texture of club brittle, snapping clean at 45°, stem not brittle,
