singly or arranged in short series and covered by the blackened 
epidermis, then more or less confluent. Asci cylindrical, sessile, 
obscurely paraphysate, 60-75 x 6-7 v -, mostly curved; sporidia 
biseriate, fusoid, curved, faintly 1-3-septate, not constricted, yel¬ 
lowish-hyaline, 30-35 X 2^-3 fX . 
In the species examined most of the sporidia showed only 
one septum across the middle, but in some two additional septa 
were visible. 
Melanconis (Melanconiella) nyssaegena E. & E.— On 
dead limbs of Nyssa multiflora, Newfield, N. J., October 23, 
1900. 
Stroma cortical, formed of the scarcely altered substance of 
the bark, circular, depressed-globose, about 2 mm. diam., rais¬ 
ing the bark into little pustules which are ruptured at the apex 
by the fascicle of black, smooth, rounded ostiola. Perithecia 
circinate, globose, black and shining inside, about \ mm. diam., 
sporidia uniseriate, elliptical or oblong-elliptical, uniseptate and 
constricted, becoming olive-brown, 30-40x12-20 tx (mostly 
12-15 '“)• 
Phyllachora serialis E. & E.— On Spartina stricta. Pa¬ 
cific Grove, Cal. July, 1900. (Robt. M. Horner, 1487). 
Stroma seriate between the nerves of the leaf, punctiform 
and buried at first, then suberumpent and more or less confluent 
for 2-3 mm. The separate stromata are about \ mm. in diam., 
and the ascigerous cells remain sunk in the parenchyma of the 
leaf. Asci densely fasciculate, clavate-cylindrical, short-stipi- 
tate, 75-80x12-15 jx . Sporidia obliquely uniseriate or subbise- 
riate, ovate, hyaline, continuous, 10-12x5-6 fx. 
Botryosphasria hysterioides E. & E.— On leaves of Hes- 
peraloe dayi, Peyotes, Mexico. April 27, 1900. (Dr. Wm. Tre- 
lease). 
Spots oblong-elliptical, soon confluent for 10 or more cm., 
reddish-brown, becoming greyish-white with a reddish-brown 
border. Perithecia globose 200-300 ft diam., lying 2-4 together 
in a narrow hysteriform stroma acute at each end, and -J-f mm. 
long, covered by the thin, whitened epidermis which is soon rup¬ 
tured by the obscurely papilliform ostiolum. Asci broad clavate 
oblong, 75-100 x 25-30 fx, contracted below into a short stipe¬ 
like base; paraphyses inconspicuous and obscure. Sporidia ob¬ 
long, slightly narrowed at the ends, with granular contents, with 
or without a large vacuole, hyaline with a slight yellowish tinge, 
25-30 x 8-12 fX. 
On the same spots are scattered perithecia with sporules of 
the Diplodia type, 5-7 x 4-5 jx (Diplodia hesperaloes E. & E.) ; 
Others with globose, brown, continuous, 6-7 [x sporules (Conio- 
thyrium sp.), others again with oblong or subcylindrical, hyaline, 
3-5 (mostly 3-) septate sporules 60-80x8-12 n (Phleospora
