242 ANNALS OF SCOTTISH NATURAL HISTORY 



P. nigra, from which it had undoubtedly spread. Saccardo 

 mentions its occurrence on several poplars, including P. alba 

 and P. candicans, both of which are common park-trees 

 near Aberdeen, but none of these are attacked. The follow- 

 ing diseases were also observed, but were not doing serious 

 damage. 



1. An Oidium on Cytisus laburnum, no ascigerous stage 



occurred. 



2. Erysiphe Martii (\A\.\ on Robinia pseudacada in a nursery 



near Aberdeen. In the same nursery the Peas were 

 severely attacked by this fungus. 



3. Hypo derma strobicola ( Hypoderma brachyspornui, Rostr.) 



on Finns Strobus in a nursery. In this case the trees 

 (about six years old) had been killed, but other factors 

 were also present which might have been accountable for 

 their death. The discomycetous fungus Peziza sub- 

 tilissima, Cke., was present, and had caused drying and 

 rupture of the bark. Of the two it seemed to be the more 

 serious agency and the primary cause of death.
