 trantibus ; contextu atro-fusco pai'enchymatico. Sporulis oblongis,

The pycnidia and spores closely resemble those of D. Hyoscyavii 

 Vest., though the latter are not quite so large ; but the creeping 

 hyphse assigned to that species wei'e not present. Unless carefully 

 examined this species may easily be mistaken for a Fhoma.

JPhoma hyalina (B. & 0.) Sacc. in Vihurno. 



Pycnidia gregarious, globose with a papillate ostiole, black, about 

 \ mm. diam., sometimes two together, long covered by the bark, the 

 ostiole then piercing it by a short slit, and at length circumscissile, 

 falling off and leaving a wide circular opening ; texture thick, paren- 

 chymatous, dark brown with an underlying purplish tinge. Spores 

 oblong-ellipsoid, obtusely rounded at both ends, thick-walled, for a 

 long time hyaline, continuous, very granular within, 21-27 x 8-10/7, 

 [" at length 1-septate, dingy-yellowish, not constricted, 20 x 10-12 /u," 

 Pass.] ; sporophores stout, nearly as long. 



On dead twigs of Viburnum Opulus. Hunt's Cross, Cheshire 

 (Ellis). April. 



Although these specimens yielded no septate spores, yet the 

 character of the spore and pedicel (the latter showing a faint 

 yellowish -brown tinge in mass) indicated that they were probably a 

 young state of a Diplodia. Moreover, the pycnidia were almost 

 exactly in accord with the description, except that there was no 

 trace of " blue," but only a distinct purplish tinge beneath the 

 brown ; they belong therefore no doiibt to Passerini's species. Plioma 

 lii/alina (B. & C.) is certainly nothing but an early stage of a species 

 of Diplodia, according to its host.
