become generally accepted in Europe, is followed here except 

 that I have referred to this species effused fructifications with 

 tuberculate surface, thick and zonate within, as well as fructi- 

 fications consisting of aggregations of small, round masses. The 

 specimen received from Bresadola has the latter form and is on 

 Prunus Cerasus; one from Romell on Salix, the substratum first 

 cited for the species, has a similar zonate structure within and a 

 tubercular surface but is more effused than that from Bresadola.
