144 Clavarias of the United States and Canada 



pi. 102), but there is no reason to think that it is not the plant so 

 labelled in his herbarium. We have two good collections from 

 Romell labelled C. aurea, one of which we take to be correct and 

 like the above (spores rough, 4.5-5 x 11-14^). The other is C. 

 flava. 



Persoon did not recognize C. aurea, nor did Fries in his earlier 

 works, but in his Epicrisis and in Hym. Europ. the latter includes 

 it and refers to plates which agree very well with the plant de- 

 scribed above. Particularly good is Bulliard's plate 222 (as C. 

 coralloides) and only a little less good is the lower figure in 

 Schaeffer's plate 287. A plant from Fries (Upsala) in the Curtis 

 Herbarium labelled C. aurea is not unlike our plants and has 

 spores slightly rough, 4.5-6.5 x 9.3-1 1{jl, just like those of the 

 Bresadola specimens referred to above. In addition to the above, 

 one of the few plates that really look like the American species is 

 that of Venturi (Studi Micol., pi. 12, fig. 112, as C. aurea). 



The species has not been recognized in the south except as 

 our Chapel Hill variety, but seems to be common in the northern 

 states. 



Juel (cited under C. cristata) finds the basidium of a plant he 

 determines as C. aurea to contain four nuclei, resulting from two 

 apical transverse spindles, the number of chromosomes probably 

 four. The spores are larger and rougher than in C. flava, and 

 contain one nucleus (pi. 3, figs. 56-66).

New York: Albany. Peck. (Albany Herb.). The spores are slightly 

 rough, 4.2-4.6 x 9.5-1 1/x. A colored drawing shows the color a pale 

 brownish yellow and the plants quite upright.

Plates 53-55, and 87 



Plants up to 11 cm. high and broad, compound from a small 

 pointed base, and at times cespitose; delicate and soft, more or 

 less rugose, branching quickly in an irregular way into a dense 

 mass, the tips ending in bluntish cusps ; color a rich buffy orange 

 (between capucine-orange and orange-buff of Ridgway) all over
