Clavarias of the United States and Canada 41 



sented in the Fries Herbarium. The only simple pink or rosy 

 plants which we have seen from America are those from Colorado 

 distributed by Clements as C. rosea and a collection from Vaughns, 

 N. Y., sent us by Burnham. It is from the last that we have 

 drawn up the above rather inadequate description. 



It will be noticed that these spores cannot be distinguished 

 from those of C. helveola, and except for color no other difference 

 can be made out. Clement's plants are small, cespitose, clavate 

 and have spores just like the above, smooth, long-elliptic, clear, 

 2.5-3.4 x 5-8{jl. Our pale flesh colored plant (No. 2788) that we 

 are considering a form of C. helveola is intermediate and has the 

 same spores. Plants received from Romell (Sweden) determined 

 as C. rosea are accompanied by colored drawings which are clear 

 pink to reddish pink. The spores of one collection (Helsingland) 

 are noted as 5-7.5 x 2.5-3 [x, in agreement with the American col- 

 lection. At the Kew Herbarium there is no authentic material of 

 C. rosea. A collection by Crossland from Hebden Bridge, deter- 

 mined as C. rosea, also has spores like the American plants. It is 

 obvious, however, that the plant interpreted as C. rosea by Cotton 

 and Wakefield (I.e., p. 188) is different from those above men- 

 tioned, and with their interpretation plants so named in the Bresa- 

 dola Herbarium seem to agree. Bresadola's plants are from Nice 

 (Barla, coll. 1889). The spores are not like those of C. helveola, 

 but are distinctly more plump, 4-5.5 x 6-8.5 (*. These measure- 

 ments agree with those given by Cotton and Wakefield. In the 

 Persoon Herbarium there are three plants that in the dry state 

 look like C. fragilis. The spores are like those of C. rosea from 

 Bresadola, large and plump, 4-6 x 5-8[x. Persoon (Myc. Europ., 

 p. 185) refers to Fries's statement that the apex in drying becomes 

 yellowish (Obs. Myc. 2 : 290. 1818). Of C. rubella, Persoon says, 

 "dilute to watery red, 2-4 plants together, but not cespitose or 

 fascicled." There is no plant under this name in his herbarium. 

 If C. rosea is to be accepted as a good species, we think it best 

 to accept at present the interpretation of Romell, whose plants 

 are from the same country as those of Dalman and Fries. 



For convenience we give below Cotton and Wakefield's inter- 

 pretation of the species :
