134 Clavarias of the United States and Canada 



C. subspinulosa the upper part in youth is whitish pink, with a tint 

 of lavender or heliotrope with concolorous tips, the deeper colored 

 cinnamon base contrasting strongly. 



A plant at the New York Botanical Garden from Italy de- 

 termined by Bresadola as C. spinulosa Pers. (Obs. Myc. 2 : 59, pi. 

 3, fig. 1. 1796) is somewhat like our plants and has similar spores. 

 There is also a collection from Blowing Rock, N. C, at Ithaca, 

 determined by Bresadola as C. spinulosa which is like our plants 

 and has spores which are identical, 4.8-5 x 9.3-1 Ijj.. Another 

 plant from Ithaca, N. Y., (Kauffman) in the Bresadola Her- 

 barium, determined by the latter as C. spinulosa, is the same ; spores 

 short-elliptic, with bent mucro, rough, 4.2-5 x 8.5-1 \.2\t.. Two 

 other collections from Italy in his herbarium so determined have 

 similar spores, and from the looks of the plants may easily be the 

 same. Bresadola is not consistent, however, in his determinations, 

 as he has quite a different plant so labelled which looks very like 

 our C. secunda or C. obtusissima. Another collection in his her- 

 barium from Ithaca, N. Y., (Fitzpatrick) labelled C. spinulosa 

 with a question is a slender form of C. stricta. Bresadola has 

 kindly reported on a typical plant of our species sent by us and says, 

 "according to the dried specimen and spores seems indeed C. 

 spinulosa, but the diagnosis does not agree." We do not see how 

 our plants can be the real C. spinulosa of Persoon, as the stem is 

 not at all like Persoon's figure, nor have the tips the peculiar in- 

 equality he emphasizes in his species. The species is not repre- 

 sented in his herbarium. It is possible that C. spinulosa is really 

 C. fennica. A fragmentary collection in the Curtis Herbarium 

 from Schweinitz labelled C. spinulosa has hard flesh and is not 

 this. The plant referred to C. pallida by Maire ( Bull. Soc. Myc. 

 Fr. 27: 451. 1911) has lilac tips in youth, similar spores, apparent- 

 ly, and grows in pine woods, but the figures referred to by Maire 

 as representing it are very unlike our plant.
