July 1905 ] Notes on Some North American Phyllachoras 161 
It corresponds quite well with Fuckel’s description in Symbolae 
Mycologicae, 219, except that the ascospores are larger. This 
does not seem to be sufficient reason for putting it anywhere else; 
Winter, in Die Pilze, gives the limitations such that it will include 
this. It has been found that different grasses show quite a varia¬ 
tion in the character of the stroma and the size of the ascospores. 
This species is one of the most common ones and is quite 
generally figured. 
Phyllachora lespedeza (Schw.) Sacc. Fig. 17-19. — This 
is found occurring on different species of Lespedeza, although fre¬ 
quently immature. On Lespedeza repens, collected by W. A. 
Kellerman on the Gauley Mountains, W. Va., and Lespedeza capi- 
tata, collected by same at Manhattan, Kansas, were found mature 
asci and ascospores. The asci were clavate to cylindrical and 
4-spored. Ascospores ellipical, uniseriate to biseriate, hyaline, 12 
x 7/i. 
Cooke, in Grev. 13:63, 1884, reports “ascis clavitit, sporidiis, 
ellipticis, continuis, hyalinis, .02 x .01 mm.” Nowhere have I 
found any statement as to the number of ascospores in an ascus. 
The character of the stroma would place it in the genus Phylla¬ 
chora. 
The only difference in the stroma on the two host-species 
were: on Lespedeza capitata they were in circular patches; while 
those on Lespedeza repens were scattered over the leaf. 
Phyllachora cornuospora Atk. Fig. 21-24. — This species 
was named and described by Geo. F. Atkinson, Bull. Cornell 
Univ. 3:1897. He kindly sent some of the material to me and 
I found that it corresponded with his description, but I also found 
(which he does not mention) paraphyses present. This is in¬ 
cluded here because it shows a curved appendage at the large end 
of the ascospore representing a peculiarity which is not common. 
Besides, this species has not been figured before. 
Phyllachora junci (Fr.) Fckl. Fig. 26-31. — This is 
found on Juncus effusa quite frequently, but is usually immature 
or sterile. Fuckel, Syhbolae Mycologicae, 216, states “sporidiis 
oblique monostichis, simplicibus, ovatis, biguttulatis, hyalinis, 12 
mik. long., 6 mik. crass.” Dr. Winter, Die Pilze, 900, gives 
“sporen schrag 1- oder 1-1J reihig, oblong, mit undeutlichen sep¬ 
tum (?) gelblich- oder grundlich-hyalin, 9-10 /x lang, 3—5.5 /x 
dick.” Ellis and Everhart, North American Pyrenomycetes, 600, 
state the same thing as is found in Die Pilze. This was originally 
described as a Sphaeria by E. M. Fries in Systerna Mycologicum, 
2:428, as a Dothidea in Summa, 387. On Juncus effusa, collected 
by W. G. Farlow at Campbella, N. B., July, 1902, the general con¬ 
ditions in the material examined were found to be the same, while 
some of the details were very different. In only one instance did 
I find the specimen in good condition for study. Fig. 27 shows an
