Clavarias of the United States and Canada 185 



In the Fries Herbarium (Upsala) are two collections labelled 

 C. flaccida, which have been kindly sent us by Dr. Juel. One of 

 these is true C. flaccida (Christian Blyth, coll.) with the usual 

 appearance and spores minutely rough, 3-3.7 x 5.5-7[/.; the other, 

 labelled in Fries's own hand, is not this species but typical C. 

 Kunsei except that the spores which are spherical (3.7-4.5(/. thick) 

 are apparently quite smooth, a character found also in the spores 

 of some American plants of C. Kunsei. As this collection could 

 not possibly be C. flaccida as described by Fries, it must be ignored 

 as evidence and added to the long list of Fries's mistakes in this 

 genus. 



In the Curtis Herbarium is a specimen from Fries (Upsala) 

 labelled C. flaccida, a small plant about 2 cm. high that looks like 

 ours and has the same spores, which are minutely warted, 

 2.8-3.7 x 5-6fx. Another collection from Fries (Upsala) in the 

 Kew Herbarium is the same thing with spores pip-shaped, minutely 

 rough, 3.4-3.7 x S-7\x. Plants from Finland at the New York 

 Botanical Garden determined as C. flaccida by Karsten are ochra- 

 ceous in the dried state and look like our plants described above, 

 except that they are a little taller. The spores are the same, being: 

 pip-shaped, minutely tuberculate, 2.6-3.3 x 5.5-6.6[a.
