Diaporthe tecta (Cooke) Sacc. 

 (Valsa tecta Cooke) 



Sand's point. Long Island, on dead twigs of M y r i c a c a r o - 

 linensis Mill. H. D. House, September 8, 1915. Professor 

 Dearness, who examined these specimens, states that Cooke does not 

 mention that the sporidia are appendiculate ; otherwise the descrip- 

 tion agrees with the specimens. 



The species is based upon Ravenel's. N. Am. F. no. 747. J. B. 

 Ellis redescribed the species from a copy of no. 747, and states that 

 the discrepancy (in part) between the two descriptions is remark- 

 able. Cooke & Ellis may have had two different species in hand. 



The same collection contains a little Calosphaera 

 myricae C. &E. 



Diaporthe tuberculosa (Ell.) Sac-c. var. pruni Dearness & House, 



var. nov. 



The perithecia, asci and sporidia are quite similar to those of the 

 typical form of this species on Amelanchier, although the perithecia 

 penetrate to or slightly into the wood on this host. The black 

 stromatic boundary also penetrates more deeply and rises distinctly 

 to the surface of the bark, elevating it into a narrow blackened cir- 

 cular ridge with a diameter of from 2 to 5 mm.

 son county, N. Y. H. D. House, May 15, 191 5.
