Clavarias of the United States and Canada 121 



This plant is just like C. botrytis in form, texture, taste, and 

 odor, but differs distinctly in color and does not reach the large 

 size of the latter. Plants of C. botrytis with tips faded are a 

 pallid, dull, fleshy cream, while the pink young tips of C. botrytis 

 and the white tips of C. flava are an unfailing means of distinction. 



From C. aiirca var. australis and C. rufcsccns (No. 2845) this 

 plant differs in smaller, more quickly branched base, different 

 color, and in the very different spores. In fading some of the 

 tips may become colored like those of C. rufcsccns, but the spores 

 will easily distinguish them. From C. formosa which also has a 

 multiple, pointed base, it differs in color, greater brittleness, and 

 smaller, smoother spores. 



Clavaria flavobrwicsccns is the same. The species was de- 

 scribed by Atkinson from plants sent him by us from Chapel Hill. 



In the interpretation of this species there has been great con- 

 fusion. The plant taken for C. flava by Fries is doubtful, but is 

 probably this. Krombholz's figure to which Fries refers is not 

 good of our plant. Schaeffers plate (on which the species is 

 based) is much like our plant and not like our C. anrca, and the 

 same may be said of Persoon's description. In Persoon's her- 

 barium is a good plant of C. flava with spores 3.7-5 x 9-1 1[A. 

 There are several European mycologists who have made it quite 

 plain that they interpret the species as we do. Vittadini's figure 

 of C. flava is excellent of our plant with the pointed base and 

 right color and shape, and his figure of C. Intca (now accepted as 

 a synonym of C. flava) is equally as good of ours. Richon and 

 Roze also represent our plant well as C. flava, showing some of 

 the tips as brownish, a point not mentioned or shown by others. 

 Neither Gillet not Quelet illustrates C. flava, but the former's 

 good description (Champ. France 1: 764. 1878) makes it pretty 

 plain that he has in mind our plant. He mentions the pale spores, 

 fragile flesh and very agreeable taste. Quelet's description is in- 

 adequate, but does not exclude our plant. He refers to Barla's 

 figure which might pass but is not good. Bresadola's figure is 

 like ours in color but diverse in form and he describes C. flava as 

 staining red on the stem and having longer spores. This would 

 indicate a larger spored form of what we are considering C. 

 sanguined. Plants in his herbarium as C. flava look like ours in
