Plants about 2-6 cm. high and 0.4-4 cm. broad, distinctly 

 stalked, the few main branches upright and usually rather long, 

 rebranching from one to three times into more or less numerous 

 rather closely pressed branches of about the same height, which 

 form a very brush-like mass, with pointed tips. Stem smooth, 

 the base somewhat incrassated by and expanding into the fibrous 

 white mycelium ; color of stem pale whitish flesh-color when young, 

 the color deepening upward to deeper flesh, the very tips concol- 

 orous or often whitish ; in age becoming tan or pale cinnamon-buff, 

 especially below; flesh pliable, toughish, nearly white or pinkish, 

 odorless, bitterish ; in drying becoming very soft, brittle and 

 chalky, and remaining light colored and quite bitter (by these 

 characters when dry easily separated from C. apiculata). 



Spores (of Burnham, No. 57) rather light buffy ochraceous, 

 elliptic with an eccentric mucro, covered with very minute warts, 

 3-4 x 7.8-8f/.. Basidia (of No. 19) 6-7 A\x thick,' with 4 slender 

 sterigmata; hymenium 50-70[x thick, not layered and not so dark 

 as in C. apiculata; threads of flesh loosely woven, much branched, 

 3-6[j. thick, irregular, walls thin, clamp connections conspicuous. 



In troops and often in lines under conifers in the northern 

 states. 



A plant at Kew from E. P. Fries (Upsala, 1850) determined 

 as C. suecica is like our plants and has similar spores, slightly 

 rough, 3.8-4.2 x 7-%. 



Clavaria circinans Pk. is certainly the same as C. suecica, as 

 shown by spores and appearance of the type plants. There are in 

 Albany plants of this species labelled by Peck C. pinca, but we can- 

 not find that he ever published this name. Clavaria flavula is also 

 the same, as shown by the type at Ithaca. Atkinson gives the 

 spores as 9-12 x 3-3. 5[x, but we find the spores, which are abundant 

 on the type, to be 3.4-4 x 7-9. 3^., in every respect like those of 

 C. suecica, and Atkinson's description does not disagree in any
