Kansas (Bartholomew). 
The usual host of this fungus is the red currant, but it is also 
found on other species of Rides and occasionally upon other shrubs 
growing near by. Specimens from Bartholomew were collected 
on living stems of Symphoricarpos occidentalis, July 24, 1895 ; and 
it has also been reported as attacking rose-bushes.

A number of specimens collected by C. L. Smith in Mexico 
and Nicaragua are in the New York Botanical Garden herbarium. 
Dr. Patouillard says they are typical P. senex. They are larger, 
thicker and more woody than plants from Florida and Louisiana 
that have been called P. senex.
