Clavarias of the United States and Canada 97 



Krombholzii Fr. with spherical spores about 6\u in diameter. A 

 collection at Albany from Finland by Karsten shows that Karsten's 

 idea of the species is entirely different. The plant is on pine bark 

 and does not look at all like ours (no spores could be found). 



Cotton has recently referred an English species to C. Kunzei, 

 and has, it seems to us, interpreted the species correctly (Trans. 

 Brit. Myc. Soc. 3 : 180. 1909). He does not associate it with our 

 American names, but a plant from Chelsea, England, sent us by 

 him is like ours and has similar spores, about 3[/. thick and minutely 

 warted. Fries's original description and Cotton's description also 

 agree well with our plant. 



Our species is certainly C. chionea, as shown by the well pre- 

 served type specimens in Persoon's herbarium. They are just 

 like our plants and have spores minutely rough, subspherical, 3.7|j. 

 in diameter. One of the typical plants sent from Persoon may 

 now be found at Kew. Fries himself later asserted the identity 

 of his and Persoon's plant. The type of C. subtilis is not repre- 

 sented in the Persoon Herbarium and its identity is very doubtful. 

 A plant labelled C. subtilis in the Bresadola collection at the New 

 York Botanical Garden (Sontagberg, Strasser) is exactly like our 

 Maine plant in appearance and spores. The tips are translucent 

 and tend to split up into fibers in both this and ours. Another 

 from him (Trentino) labelled C. gracilis is not our C. gracilis but 

 the above, with the same appearance and spores (4x4.8;/., min- 

 utely warted), and this is true of several collections labelled C. 

 gracilis in the Bresadola Herbarium at Stockholm. The interpre- 

 tation by Bourdot and Galzin of C. subtilis differs from that of 

 Bresadola. They give the spores as "finely rugose, 5-6 x 7-8[x." 

 (Bull. Soc. Myc. Fr. 26: 216. 1910). We have received several 

 collections of C. Kunzei from Romell: one (Stockholm, Sept. 4, 

 1898) labelled with a question has spores subspherical, minutely 

 rough, 3.4-3.8 x 3.8-4. 8[/.; another (Aug. 8, 1912), spores about 

 3x3.7[x; and a third (Sept., 1915) labelled C. gracilis has spores 

 subspherical, about 4[x thick. For another collection of C. Kunzei 

 see so-called C. flaccida in the Fries Herbarium. 



In the Schweinitz Herbarium is part of a plant of his C. snb- 

 corticalis in good condition which proves his species to be C.
