BURT — THE NORTH AMERICAN SPECIES OF CLAVARIA 25 



"Lignicola, 8 cm. alta, basi simplici, subtereti, 2 cm. alta; 

 ramis subdichotomis, supra dumosis, compressis, siccitate sul- 

 catis; planta tota carnea, dein cinnamomea, velutino-pruinosa ; 

 sporis ellipticis, echinulatis, flavido-brunneis, 6 mX8 p. 



"Growing in clumps on rotten wood, Prince Rupert's [Do- 

 minica, W. I.], March 1894. No. 917. 



"Among rotten leaves, St. Aroment, Aug. 1892. No. 419. 



"The flattened branches and the brownish echinulate spores 

 seem to indicate Thelephora rather than Clavaria for this species, 

 but the hymenium covers the whole surface of thel plant and 

 necessitates the placing of it in the latter genus." 



I have seen no specimen of this species ; the colored, echinulate 

 spores seem to show relationship with the C. cyanocephala group 

 of species, from all of which this differs in the subglobose spores 

 and occurrence on wood. 



29. C. pinicola Burt, n. sp. Plate 5, fig. 32. 



Type: in Mo. Bot. Gard. Herb. 



Fructifications rarely solitary, usually in clusters of 2-6 from 

 a common white mycelium, slender, of rather uniform diameter 

 throughout, sometimes simple but usually once to thrice dichoto- 

 mously forked, the branches cylindric, spreading, drying every- 

 where buf fy brown, the apices acute ; spores slightly colored under 

 the microscope, even, 7 1 / 4-9X4 1 / 4-5p. 



Fructifications 1-3 cm. long, trunk and main branches 1/3-3/4 

 mm. in diameter. 



On bark of log of Pinus contorta. Priest River, Idaho. Oct. 

 10, 1920. J. R. Weir, 169^6, type (in Mo. Bot. Gard. Herb., 



57689). 



C. pinicola is very distinct from any other American species; 

 it is related in aspect to C. delicata Fr., represented in Curtis Her- 

 barium by an authentic specimen from Fries, which has hyaline 

 spores 5-6 X 2% p. C. delicata is more fully described as No 



of 



C. byssiseda is of somewhat similar 



but has hyaline spores 12-16 p long 



30. C. brunneola Berk. <fc Curtis, Linn. Soc. Bot. Jour. 10: 338. 

 1868; Sacc. Syll. Fung. 6: 711. 1888. Plate 3, fig. 24. 



Type: in Curtis Herb, and probably in Kew Herb. — Also 

 distributed in Wright, Fungi Cubenses Wrightiani, 462.
