While it is considered by some that this Accidium belongs with Puc- 

 cinia Physalidis Peck, there is no definite proof to tliat effect either by 

 cultures or otlierwise. However, the fact that the two forms are largely 

 co-regional and also that they resemble each other in general habit might 

 be taken to reinforce the above supposition, but cultures are necessarj' to 

 pi-ove or disprove it definitely. No doubt the better way to make the cul- 

 ture is to sow fresh aeciospores on a sterile plant of their own host. The 

 species is distinguishable from Accidium Solani Mont, by its sniall aecio- 

 spores and its revolute and more coarsely lacerate peridium.
