BURT — THE NORTH AMERICAN SPECIES OF CLAVARIA 71 



though more transparent. At first sight it had somewhat the 

 appearance of T. dissecta, Lev., a very differently constructed 



species." 



Fructifications now pinkish buff with whitish mycelium at 

 the base; spores hyaline, even, globose, 4-5 \i in diameter. 



106. C. delicate Fries, Syst. Myc. 1 : 475. 1821 ; Hym. Eur. 

 670. 1874; Sacc. Syll. Fung. 6:699. 1888. Plate 11, fig. 111. 



Type: authentic specimen from Fries, collected at Upsala, 

 Sweden, in Curtis Herb. 



"Tenella, e basi ramosa, Candida, deorsum villosa, ramis gra- 



cilibus, elongatis, teretibus, aequalibus, erectis, acutis 



Ad ligna mucida Fagi. Eximia." 



Fructification now sorghum-brown to Rood's brown, somewhat 

 rugose, attached to the wood by a whitish mycelial base; spores 

 hyaline, even, somewhat curved, 5-6 X 2 1 /2 M- This fructification 

 is not on Fagus but on coniferous wood, for the wood substra- 

 tum consists of tracheids with bordered pits. 





107- C. scabra Berkeley, Hooker's Jour. Bot. 8: 277. 1856; 

 Sacc. Syll. Fung. 6: 728. 1888. Plate 11, fig. 112. 



Type: probably in Kew Herb., a specimen from the type 

 collection in Curtis Herb. 



"Simplex umbrina acuminata pusilla scabra; basi tuberosa, 

 setis erectis strigosa. Spruce, n. 157. 



"Hab. On the ground. Panure. [Brazil]. 



"About 1/3 of an inch high, gregarious, subcaespitose, pale 

 umber, simple, erect, acuminate, scabrous with little rough gran- 

 ules; base tuberose, clothed with white or pallid, erect bristles. 



"This is in many respects like Calocera tuberosa, but it ap- 

 pears to be a true Clavaria, and is distinguished by its smaller 

 size, scabrous hymenium, and the erect or slightly divergent, 

 not deflexed, bristles at the base. — There is another simple 

 Clavaria in the collection, growing on a green substance, which 

 appears to be an anamorphosis of some Lichen. The specimens 

 are however too imperfect to afford much information." 



The fructifications have dried resin color (somewhat cin- 

 namon) with the base whitish; spores not certainly made out 

 in my preparation, possibly minute, even, subglobose, 1^-2 m 

 in diameter.
