PHEAGMIDIUM. 



(Plate 45.J 



Figures have been executed of several species of Fhragmidium, 

 wbicli will be found on plate 45. Tbese are drawn by camera 

 lucida to the same scale as the figures of Peziza, about 400 diam., 

 but the accurate scale will be found at the bottom of plate 28, by 

 means of which the figures may be measured.

All the above are British, with the exception of Phragmidium 

 speciosum, Fr., which is North American. Phragmidium granula- 

 tum, Rabh., on leaves of Potentilla alba, would seem to be a good 

 species, although most of the continental names are merely syno- 

 nyms of one or other of the species which we have figured. 



We have just received from Professor Passerini a species of 

 Triphragviium on Spircea filipendula which differs from Triphrag- 

 mium Ulmarice in the spores having a smooth and more delicate 

 epispore. It should, perhaps, be regarded as a distinct species.
