VERRUCARIEiE. 41 



Sussex ! Mr, Borrer. Bickley Coppice, near Shrews- 

 bury ! 



The apothecia, in both varieties, when viewed from 

 above, are oblong in their outline, and the rather large 

 iniperf oration partakes of the same shape. The spreading 

 base of the perithecium gives the appearance of a paler 

 black cloud or shading off around the apothecia. 



Verrucaria Cerasi, Schrad. and Ach. 276, which Fries 

 makes synonymous with V. epidermidis, Ach., has, in 

 specimens ! collected in the Pyrenees by Mr. Spruce, a 

 perithecium generally similar to that of epidermidis ; but 

 the sporidia are very narrow, linear-oblong, triseptate, 

 and the asci are of a very peculiar form, like the cartouche 

 in Egyptian inscriptions. 



7. V. puNCTiFORMis, Pers. Perithecium hemispherical, 

 spreading at the base; sporidia 8 in asci, very 

 minute, linear-oblong, uniseptate, pale-yellow. Plate

Sussex ! Mr. Borrer. 



The very minute apothecia viewed from above are 

 round in their outline, like those of V. cinerea, not oblong 

 as in epidermis and its variety analepta, and the imper- 

 foration is round and very large. V. punctiformis. Fries, 

 447, is not our plant, but rather our V. ciiierea.
