BURT — THE NORTH AMERICAN SPECIES OF CLAVARIA 33 



also a little smaller in the American gatherings than the dimen- 

 sions given above. 



43. C. rufipes Atkinson, Ann. Myc. 6 : 57. 1908 ; Sacc. Syll. 



Plate 6, fig. 43. 



Fung. 21: 430. 1912. 



Type: in Cornell Univ. Herb. 



"Plants entirely white, base of stem tinged rufous, about 2 cm. 

 high, branched like Clavaria muscoides, tips blunt and slightly 

 enlarged. Basidia 4-spored. Spores oboval, granular then with 

 an oil drop, smooth, 4-6x2,5-3 p.— C. U. Herb., No. 14037, 

 ground, Six Mile Creek, Ithaca, N. Y. Whetzel, Oct. 10, 1902." 



Stem branched at apex into filiform branches which are now 

 resinous (nearly Sayal brown), the stem tapering downward, now 

 paler than the branches; spores hyaline, even, 4-6X3^4 m- 



C. rufipes is sharply distinct from the other white species by 

 its small size, form suggestive of the fresh water hydra, and small 

 spores. C. exigua, our other small species, was described as 

 having a white stem and branches somewhat lavender. 



44. C. asperula Atkinson, Ann. Myc. 6: 54. 1908; Sacc. Syll. 



Plate 6, fig. 44. 



Fung. 21: 430. 1912. 



Type: in Cornell Univ. Herb. 



"Plants branched from the base often forming broad tufts, 

 1-4 cm. high, tufts 1-4 cm. broad, entirely white, sometimes 

 after drying becoming more or less discolored, brownish etc., axils 

 of branches rounded, branches more or less divergent or arcuate ; 

 tips divergent or arcuate, acute; base of trunk often tomentose. 

 Spores minute, oboval, granular or with a small oil drop, as- 

 perulate, 3-5x2-4 u. — Ground, woods, rather common at Ithaca, 

 N. Y. Some of the collections in the C. U. herb, are as follows 

 No. 13550, Beebe Lake woods, Whetzel, Aug. 13, 1902; No. 15216, 

 Buttermilk Gorge, July 15, 1903, Kauffman; No. 13284, Coy 

 Glen, C. O. Smith, Aug. 4, 1902. Ithaca, N. Y." 



My notes on C. asperulans apply also to this species. In C. 

 asperula the fructifications are a little larger and fewer spores 

 are even than in C. asperulans but of the same form, dimensions, 

 and rough wall. The gathering of C. asperulans is probably a 

 little less mature than those of C. asperula. 



I have collected this species in Vermont. It has been dis- 

 tributed from New Hampshirel in Reliquiae Farlowianae, 305, 

 under the name Clavaria corniculata.
