Cercospora euonymi Ellis. On Evonymus atropurpureus. Dur¬ 
and. 
In this collection the conidiophores are hyaline, 35-50x3/ji the 
hyaline conidia cylindrical to obclavate-cylindrical, 30--50x3-4i/2/x. 
Despite the Mucedinous character and the smaller conidiophores 
and conidia it is unquestionably the parasite described under this 
name by Ellis and issued in Fungi Columhiani, 2211. The white 
spots with the broad dark purple border are conspicuous.

Entyloma linariae Schroet. var., gratiolae n. var. Causing spots 
which are orbicular, yellowish white, 1mm. or less in diameter 
or larger and indefinite; spores broadly elliptical to globose with 
epispore varying from nearly smooth to verrucose, 13-18/i, long. In 
leaves of Gratiola virginiana. Cadott, Wisconsin, July 22, 1920. 
The epispore in Entyloma linariae Schroet. is variously described 
by authors as being smooth, irregularly angularly thickened or 
as having a wavy outline because of low projections. In the col¬ 
lection referred to here some of the spores are studded with pale 
verrucosities which are perhaps the remains of the gelatinized 
hyphae. The form on this host is probably physiologically distinct 
from the var. veronicae Wint. (E. veronicae Lagh.) as well as from 
the type.

Notes on Distribution and Abundance 
It is purposed to supplement the list of parasitic fungi occur¬ 
ring in Wisconsin with some notes on the distribution and fre¬ 
quency of the species in the state based upon the specimens pre¬ 
served in the Davis and the University of Wisconsin herbaria 
and field observation. In attempting this one meets the fact that 
infection is dependent on variables and hence a parasitic flora is 
far from uniform. This seems to be especially true of those forms 
which infect by means of zoospores.
