Clavarias of the United States and Canada 105 



Clavaria arborea Atk. Ann. Myc. 6 : 56. 1908. 



The following is the original description : 



"Plants very much branched dichotomously, curved and some- 

 times deformed, white to alutaceous, terminal branches rose-pink, 

 or yellowish brown probably when old. Basidia 4-spored. 

 Spores obovate, asperulate, white, 3-4 x 2-3[*." 



We have examined the type and also another collection in 

 Ithaca from the same place. The former consists of one plant 

 and pieces. It is repeatedly but not abundantly branched and 

 rather tall and narrow. No spores could be found on it. The 

 second collection is smaller and only slightly branched, the 

 branches spreading. 



As the spores and basidia do not differ much in the description 

 from those of C. Kunsei and C. subcaespitosa it may be a color 

 form of one of them.

This is known only from Mt. Mitchell. The type consists 

 of one tall, narrow plant with very numerous tips ; the spores as 

 described. Atkinson's description is as follows : 



"Plants ochraceous, 5-7 cm. high. Trunk short, primary 

 branches open, bases divaricate, axils rounded, upper branches 

 fastigiate. Plants soft, flexible. Spores small, white, oboval, in- 

 equilateral in side view, with an oil drop, 4-5 x 2.5-3[x, with a few 

 scattered short spines."
