Clavarias of the United States and Canada 201 



acute, equal throughout the club, pale yellowish to leather color, 

 even or crumpled, glabrous or at times finely pubescent all over, 

 with a small clean-cut hollow, the base attenuated, attached by 

 fibrous mycelium and strigose-hairy where protected ; texture deli- 

 cate and soon withering but not fragile or brittle even when dry. 

 Flesh of densely compacted, parallel cells of parenchyma-like 

 appearance in cross section. 



Spores of plants from Vaughns, N. Y., white, smooth, oblong 

 to pip-shaped, with a large mucro, 3.8-4.8 x 6-9.3[a (a few up to 

 10.5;/.). Basidia 4-spored, about 6.5(ji thick. 



Growing among leaves of deciduous trees during very wet 

 weather in northern latitudes. The tomentose form occurs with 

 the smooth and is what is called var. vivipara by Fries. Bulliard's 

 figure shows both forms on the same leaves. Harper (Mycologia 

 10: 56. 1918) gives the spores of his Michigan plants as 4-5 x 

 9-12[a, while Schroeter says they are 4-5 x 8-9[x. Clavaria juncea 

 is well represented in the Persoon Herbarium by plants of the usual 

 appearance. The type specimens of C. virgultornm in the same 

 herbarium show clearly that it is the same as C. juncea, but we 

 could get no spores from them. Clavaria filata Pers., which is 

 considered a synonym of Typhula incarnata Lasch ex Fries by 

 Fries and others, looks in the dry state exactly like this species, 

 but we could find no spores other than small spherical ones that 

 appeared to be those of a mold. A tuber is not mentioned by 

 Persoon. Others have noted the close kinship of this group, and 

 Gillot and Lucand (Cat. Rais. Champ. Sup., p. 439. 1891) treat 

 T. phacorrhiza as a variety of Clavaria juncea.
