The only reference? to the existence of the hollyhock fungus in 
this country is in the catalogue of Pacific coast fungi by Hark- 
ness and Moore, where it is said to have been found on Malva, 
near San Francisco. A fungus related to the hollyhock fungus 
has been observed on species of Malvastrum in the western states 
and California. It was first seen by Mr. D. Cleveland, near San 
Diego, in 1875, and has been seen several times since. By some 
the fungus on Malvastrum has been considered distinct, and even 
those who have considered it a variety of P. Malvacearum have 
regarded it as distinctly unlike the form found on hollyhocks. 
When in California I examined with care the different Malvacee, 
to which order the hollyhock belongs, to see whether the true 
other hand, if the Malvastrum fungus is really a distinct p sei 
then the hollyhock disease of Europe is not the hollyhock diseas 
of this country, although both are caused by nearly related Pue- 
cinie of the sub-genus Leptopuceinia. A detailed account of the 
differences recognized in the two forms mentioned is only of inter- 
est to mycologists, and a discussion of the subject will come up 
ee 
to be apprehended from Puecinia heterospora B : 
its different forms is widely distributed on different Malvacex 12
