placed with equal propriety in Atractium or Harpographium. 
Atractium differs from Arthrosporium in the shape of the spores; 
Harpographium differs in the colored hyphae and in the simple 
spores. 
The type specimens are in the Carnegie Museum, Pittsburgh,

Phyllosticta Atriplicis Desm. 
From published descriptions, Phyllosticta Atriplicis Desm. and 
Septoria Atriplicis (West.) Fuckl. may be the same species. I 
have not seen the type specimens of either species and therefore 
cannot say definitely that such is the case, but specimens collected 
on leaves of Atriplex hastata L. during the summers of 1909. 
1910, 1911, and 1912 may throw some light on the matter. The 
specimens were collected at different places in Wilkinsburg and 
always showed remarkable uniformity in growth and develop- 
ment. 
The examination of fresh specimens showed pycnidia with 
long, guttulate, and apparently non-septate spores. The spores in 
old dry specimens appeared to be distinctly septate. This peculiar 
condition in spore character made the determination of the plants 
difficult. The long non-septate spores indicated the genus Phoma 
or Macrophoma; the older septate spores pointed to the genus 
Septoria. 
It is probable that the septation in the older spores is due to the 
contraction of the protoplasmic mass in drying and therefore the 
septa are not true but only apparent. 
Three species of Phoma are reported as growing on Atriplex: 
Phoma longissima, Atriplicis, Westendorpii. The spore measure- 
ments for these three species range from 4-10 p in length. The 
spores in my specimens are more than twice that length and,, 
consequently, cannot be referred to any of these species. 
Phyllosticta Atriplicis Desm. is described as having spores 
cylindric, ovate, straight or curved, 3-6-guttulate. The length of 
the spores is not given. Septoria Atriplicis (West.) Fuckl. has 
cylindric or subfusoid spores, 4.5-5 X 25-35 4, spuriously 1-2-3- 
septate. The spores in this latter species agree fairly well with 
the spores in my specimens. lit may be possible, then, that these
