Aecidium in the latter case is acicoluus and not like the corresponding 

 European form corticolous. 



We have arranged the following references under three heads: those 

 where the Aecidium is reported on hark, those on leaves and lastly miscella- 

 nea. Probably some of the references properly belong to certain of the species 

 already given here as cross references.
