2299. Cucurbitaria Lauro-cerasi Phill. & Plow. Grevilha, 

 Vol. X. p. 72. PL 158,/ 8, (a) the plant enlarged, (b) 

 ascus, (c) sporidia. 



Perithecia crumpent, 1 to 4 in a group, globose, 

 smooth, small ; ostiola inconspicuous ; asci cylindrical,. 

 •I2--I25 x *2 mm. ; sporidia- uniseriate, dark brown, 

 oblong, ovate, slightly constricted about the middle, 

 muriform, '02--02 5 x -'02 mm. 



This species comes near Fuckel's C. coryli (Nach. 

 I. p. 20), as far as the size of the sporidia, but differs 

 in other characters. The sporidia have often seven 

 primary transverse septa — four in upper half of the 

 sporidia and three in the lower.
