Diaporthe tecta (Cooke) Sacc. 
(Valsa tecta Cooke) 
Sand’s point, Long Island, on dead twigs of Myrica caro- 
fmemsis Mill. “Ho. 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.

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.
