On base of stems of Antirrhinum, Birmingham, May. The 

 oily contents of the cells of the spore assume different appearances 

 according to age, and may even look, at first sight, as if there 

 were more than one septmn.

Pycnidiis confertis, plerumque in series secus fibras culmi 

 digestis, tectis, minutis, depresso-sphcericis, atris, ca. 150 fj. diam. ; 

 ostiolo epidermidem laceratam vix perforante ; contextu parenchy- 

 matico, atro-olivaceo. Sporulis fusoideis, a fronte visis ferme 

 rectis, a latere lunatis v. arcuatis v. flexuosis, deorsum acutioribus, 

 granulosis, guttulis paucis irregularibus praeditis, 13-19 x 3 /x ; 

 sporophoris vix conspicuis. (Tab. 542, fig. 9.)

 theciis quibusdam PJiysalosjJoram simulantibus (an Leptosphceria 

 eadem junior?). The pycnidia are seated on a sparse creeping 

 dark-olive articulated mycelium. Distinguished from the type 

 chiefly by its smaller and narrower spores, its habitat, and the 

 absence of the spots. The spores frequently have the exact 

 shape of a boomerang.

There can be little doubt that this is a form of D. Saccardiana 

 Speg, (Splicdropsis Sacc. Syll. iii, 292). It differs from that species 

 in its larger pycnidia, which are not arranged in lines, in the 

 larger and at length septate spores, and the total absence of the 

 described "striae." If it is a variety, then Spegazzini's species 

 must be a Diplodia, not a Sphoiropsis. Many pycnidia were 

 examined that showed none but colourless spores, reminding one 

 of a Macrophoma, but a faint suspicion of colour in some of the 

 spores induced further investigation, until at last in a few of the 

 largest pycnida the mature spores were discovered. The septa are 

 variable ; usually there is one septum in the middle, but occa- 

 sionally it is nearer to one end, and in a few cases there were two
