Clavarias of the United States and Canada 159 



That this is C. apiculata Fr. does not seem open to doubt. 

 Fries's description does not disagree in any point (except that he 

 describes the tip color as sometimes greenish.) We have three col- 

 lections of C. apiculata from Stockholm sent us by Romell and so 

 determined by him. They occur on coniferous wood and agree in 

 every respect with the American plants. For example, the spores 

 in one case are 4-5 x 7.5-9.3(jl, faintly rough; hymenium complex, 

 containing embedded spores. The threads of the flesh in many 

 cases have very thick walls, in places closing the lumen. One col- 

 lection is noted as having the tips green, and this occasional varia- 

 tion to green tips is the only difference that is to be made out in the 

 European plant. At Kew is a collection in poor condition of C. 

 apiculata from E. P. Fries (Upsala, October, 1856), which has the 

 same dark tips well shown; spores 3.8-4.5 x 6-9.7[a. This is also 

 the plant called C. apiculata by Schweinitz, as evidenced by a col- 

 lection in his herbarium which is similar in appearance and spores 

 (4-5 x 8-9.2[x). There is also a specimen from Schweinitz in the 

 Curtis Herbarium (no locality given) labelled C. apiculata which is 

 the same. Its spores are minutely rough, elliptic, 3.7-4.4 x 

 6.7-8. \\x. From a collection labelled C. abictiua from Schweinitz 

 in the Curtis Herbarium, it appears that his conception of that 

 species was incorrect. The spores, which are short-elliptic, min- 

 utely rough, 4.8-5.5 x 7.5-9.3^, show the plant to be C. apiculata. 

 It is to be noted further that the plants early referred by Peck to 

 C. apiculata ( Rept. N. Y. St. Mus. 24: 82. 1872) are the same as 

 his C. Tsugina. After examining carefully the type of C. Tsugina 

 as well as numerous other collections determined by Peck at Al- 

 bany, we find no difference between it and our plants described 

 above. In a good plant of C. Tsugina from Piseco determined by 

 Peck, spores are minutely rough, 4 x 8.5-9.5(j.. In Albany there are 

 several collections of small plants on coniferous wood that were 

 determined by Peck as C. byssiscda. They are almost certainly 

 young plants of C. apiculata, and look just like our No. 2962. No 

 spores could be found on them. 



Clavaria virgata Fr. may also be this species. A fragment so 

 labelled by Schweinitz from New York State now in the Curtis 

 Herbarium looks much like C. apiculata, but we could find no 

 spores on it. Fries gives it as growing on rotten pine wood, and
