GYMNOSPORANGIUM 307 
Aicidia on leaves, branches and fruits of Crataegus Oxy- 
acantha, C. monogyna, Mespilus ger- 
manica, Cydoma vulgaris, June— 
August; teleutospores on Juniperus 
Sabina, April and May; uncommon. 
(Fig. 232.) 
The course of the life history of this 
species is identical with that of the pre- 
ceding. It is distinguished by its shorter 
and broader teleutospores, which resemble 
those of G. Sabinae, but the ecidia are 
quite different from those of that species 
and resemble those of G. clavariaeforme., 
The ecidia of G. confusum are reported 
also doubtfully on Pyrus communis and 
Cotoneaster integerrimus. The cells of the 
peridium have their side-walls marked 
with elongated obliquely placed ridges, 
while those of @. clavariaeforme have them 
coarsely warted. This description is taken 
from Fischer and Plowright, both of whom 
give long accounts of its peculiarities. In 
all Plowright’s specimens of G. confusum 
(produced artificially on Hawthorn, Quince, 
Medlar) the peridia were smaller, shorter,
