98 Clavarias of the United States and Canada 



Kunzei. The spores of the specimen are subspherical, asperulate, 

 about 3[u in diameter. We have examined plants of C. asperula in 

 the Cornell Herbarium from Ithaca and from North Carolina, and 

 find them identical in appearance and spores with our Chapel Hill 

 plants. There is also an authentic specimen from Ithaca in the 

 Farlow Herbarium. We have not been able to find the type of C. 

 asperulans at Ithaca, but from the description it is probably the 

 same as C. asperula. Clavaria velutina is shown by the type from 

 Newfield, N. J., to be this species, with spores minutely warted, 

 subspherical, about 2.5-3.2[x thick. A letter from Dr. Farlow to 

 Ellis at the New York Botanical Garden shows that he had com- 

 pared specimens of C. velutina from Ellis with L. subsimile in the 

 Curtis Herbarium and thought them the same. In Bresadola's 

 herbarium a collection from Atkinson of typical C. Kunzei is 

 labelled "C. velutina E. & E.=L. semivcstitum B. & C", but we 

 find the spores of the latter species quite different. Clavaria 

 dealbata Berk. (Hooker's Journ. Bot. 8: 275. 1856. Lachnocla- 

 dium dealbatum (Berk.) Cooke. Grevillea 20: 10. 1901) is very 

 near this species. The spores of the type at Kew (Spruce, No. 

 159) are almost identically like those of the present species, 

 spherical, minutely asperulate, 3-3.4;x thick (pi. 91, fig. 10) ; but 

 the dried plants look more like C. angulispora. From the types 

 at Kew and in the Curtis Herbarium C. pallida B. & C. (Journ. 

 Linn. Soc. 10: 338 [1868] 1869) does not seem separable from C. 

 dealbata. The spores are the same in both the Kew and Curtis 

 specimens, minutely warted, spherical, about 3-3. 7\x thick. 



It is apparently this species that Oudemans had in mind in re- 

 porting C. subtilis (Kruidk. Arch., 3rd ser., 2: 674. 1902). He 

 says: "Species growing on the ground, small, simple or branched 

 (once or twice forked) at the stem, branches slender, white or 

 pale gray, reaching about the same level. Spores colorless, 

 2 x 3.5[x in diameter. Height of our examples 1-2 cm. ; thickness, 

 0.5-1.5 mm. On earth in shady places." 



Our microscopic study of sections of a number of specimens 

 that we are referring to C. Kunzei, while agreeing rather closely 

 in the size and appearance of the plant as well as in the size and 

 form of the spores and basidia, and size and arrangement of con- 

 text threads, show on the other hand certain differences that may
