Clavarias of the United States and Canada 181 



Spores of C. abietina from Bresadola (N. Y. Bot. Gard.) are 

 pip-shaped, 3.5-3.8 x 6.5-7[x, minutely papillate, ochraceous. The 

 plants are small, not over an inch high. Others in his own 

 herbarium are similar. Other European specimens under this 

 name in the New York Botanical Garden Herbarium vary much 

 in delicacy and some cannot be distinguished from the flaccida 

 form, which is supposed to be more delicate. A good collection 

 from Upsala sent us by Romell and determined by him as C. 

 abietina with C. ochracea von Post (not published) as a synonym 

 looks just like our plant of pines, and has the same spores, which 

 are dark colored, distinctly warted, 4 x 7-8.2[x. In regard to this 

 Romell writes: ''Clavaria abietina which von Post called 'ochra- 

 cea is to my eyes distinct from the 'forma minor, contrita 

 virens' which von Post called 'cyanescens' and which must be very 

 like to and perhaps is sometimes considered as 'flaccida ere the 

 color is changed." Plants received from Romell labelled "C. 

 cyanescens v. Post=C. abietina forma Fries, Stockholm, autumno, 

 1889" are indistinguishable from C. flaccida in the dried state, with 

 spores, 3.6-4.2 x 6-7.4^. We have received from Juel (Upsala) 

 as C. abietina typical plants which are distinctly green in the dried 

 state; spores pip-shaped, often narrowly so, distinctly rough, 

 3.4-4.2 x 7-9[x. Another collection from him looks more like our 

 form of pines. Clavaria testaccoflava Bres. may be distinguished 

 by larger spores, yellow tips and vinaceous color of flesh when 

 bruised. It is 3-5 cm. high and grows in fir woods in mountains. 

 Still another plant of the same size and habit as C. flaccida and C. 

 abietina and with stringy mycelium is C. Patouillardii Bres., 

 which see. 



Juel (cited under C. cristata) studied this species and finds the 

 basidia filled with yellow granules, short, the nuclear spindles 

 apical and transverse, the four spores elongated and spiny and 

 figured with one nucleus (pi. 3, figs. 67-69). 



The plant from Utah, entered below, is strongly olivaceous in 

 places, with densely crowded, thick, short branches, the spores as 

 in C. abietina except that they are larger. It may prove to be a 

 distinct varietv.
