aphysate, 80-105x10-12 pi. Sporidia biseriate, fusiform, slightly 

 curved, hyaline, 22-30x4-6 fi, sometimes Avith a short, hyaliue 

 appendage at each end. 



On dead herbaceous stems, Louisiana (Langlois, 1437). 



The sporidia are for some time only 1-septate, but finally become 

 3-5-septate and yellowish hyaline. The figs. 7-9, tab. Ill, Berlese 

 Icoues, represent the sporidia very accurately. 



Of the two Nos. in Sydow's Mycotheca Marchica issued as L. 

 preemorsum, 25 7is a Diplodia and 985 a brown-spored Lophiostoma, 

 (at least in our copy).

Perithecia scattered, prominent, rounded, subdepressed, black. 

 Ostiolum narrow, compressed, small, sometimes subconical. Sporidia 

 elongated-oblong, 6-7-septate, with one or more cells divided by a 

 longitudinal septum. 



On branches of CratcBgus, Cornus, &c., (Europe), Carolina and 

 Pennsylvania (Schweinitz). 



There is no black spot. The perithecia on decorticated branches 

 are bare : on limbs with the bark on, emergent, unequal, soon empty, 

 and the ostiolum broken, truncate, sometimes conical.

 erumpent, spherical or somewhat compressed and elliptical. Asci
