but these do not differ in other respects from stromata in which 

 the contents of the hyphse are colourless ; the former, which 

 are the more highly coloured internally, give no coloiu" with 

 potash. 



The glaucous " bloom " on the surface of the young stroma is 

 due, as remarked by Parkin, to the development of a svuface 

 layer of scattered conidiophores and conidia ; the conidiophores 

 are about 12 jjl long, and the conidia smaller (5-8 x 1-1 • 5 ^,) than 

 those in the normal pycnidia.
