Harknessia rhoina E. & E.— On dead leaves of Rhus in- 
tegrifolia, still hanging on the tree. Claremont, Calif. Nov. 1903. 
(C. F. Baker, 3948). 
Perithecia epiphyllous, scattered, medium size, ovate, base 
sunk in the substance of the leaf, upper half projecting with a 
round formation at the apex. Sporules elliptical, brown, subine- 
quilateral, about 20 x 10 fx, on filiform hyaline basidia, about 25 fx 
long. 
Diplodia fairmani E. & E.— On dead limbs of Menisper- 
mum canadense. Lyndonville, N. Y. Oct. 1900. 
Perithecia scattered, small (-J mm.), covered by the epidermis 
which is raised into little pustules and tardily ruptured. Sporules 
elliptical, uniseptate, constricted, brown, 20 x 10 fx. 
D. hypoxyloides E. & E. on the same host, has perithecia 
twice as large and sporules 12-16x4-5^^ and differs otherwise. 
Dothiorella toxica E. & E.— On dead limbs of Rhus tox¬ 
icodendron, Riverside, Ill. March 1903. (E. T. & S. A. Har- 
per 795)- 
Stroma acutely elliptical, 1 mm.-J cm. long, bursting out 
through longitudinal fissures in the bark. Perithecia 2-6 in a 
stroma, ■£-£ mm. diam., white inside, with a papilliform 
ostiolum, basidia as long or longer than the sporules, which are 
broadly elliptical, 1-3 guttulate, hyaline, 12-20 x 10-12/x, or sub- 
globose, IO-I2 }X. 
This differs from D. rhoina E. & E. in its much larger spo¬ 
rules and acutely elliptical stroma. 
Ceuthospora abietina E. & E.— On dead limbs of Abies 
balsamea. Harraby, Lake Rousseau, Ontario, Canada, Sept. 
1902. (E. T. & S. A. Harper, 792). 
Stroma cortical, valsiform, circular, about 1 mm. diam., 
raising the bark into flattish pustules crowned with the small, 
black, papilliform ostiolum. Perithecia ovate, 2-6 in a stroma, 
membranaceous. Sporules cylindrical, straight, or nearly so, 
6-7 x 1J ix, on filiform basidia longer than the spores. The peri¬ 
thecia have their ostiola all united into a central one. 
Ascochyta confusa E. & E.— On leaves of Smilax hispida. 
Yates, New York. Oct. 1900. (Dr. C. E. Fairman, 1512) ; and 
on leaves of Smilax, Harpers Ferry, W. Va. (E. T. & S. A. 
Harper, 926). 
Spots amphigenous, round or irregular, 2-5 mm. diam., white, 
thin, almost transparent, with a narrow, dark-brown, raised bor¬ 
der. Sporules ovate or elliptical, smoky-hyaline, 7-12 x 3J-4-I ^ 
Ascochyta smilacis E. & M. Am. Nat. Dec. 1882, p. 1002, 
has sporules 11-22 x 6-7 / x .
