225 3 ; 
young conidiophorous, covered with needle-shaped basidia 35-40 
X 2-3 #, bearing oval or broadly fusoid conidia, 3.5-4 X 7-10 #. 
- When mature composed of three strata of different color, the inner 
whitish tinged with pink, intermediate layer light ochre, and outer 
layer cinnamon. The intermediate layer is less compact than the 
other two. Perithecia 1 mm. long by one-third millimeter in 
diameter, singly or in groups of 3-4 or 20, or crowded, sometimes 
branching below. Asci large, 450-750 X 14 #, tapering to a 
slender point at base, more gradually toward the somewhat 
enlarged, conoid, truncate apex. Spores pluriguttulate as well as 
pluriseptate, nearly as long asthe ascus. Onstems of Avuxdinania 
macrosperma var. suffruticosa, Ala. and S. C. 
Among the other material collected in Alabama is a gramini- 
colous fungus, which at the time of collection I took to be, from 
its external appearance, the same as Dothichloé Hypoxylon. Upon 
examination it proves to be very different, and is the type of a. 
new genus for which the name Myriogenospora is here proposed. 
Although the spores are not strictly linosporous and the species 
belongs plainly to the Dothideacez, it seems well to characterize 
_ it here. 
MYRIOGENOSPORA Atkinson. 
Stroma pulvinate, effused, carbonaceous. Perithecia im- 
Mersed, confluent with the stroma, crowded, apex not very prom- 
ment. Asci subcylindrical, many-spored. Spores slender, con- 
tinuous, hyaline. 
Myriocenospora PAspati n. sp. 
Stroma one to two centimeters long, seated upon one side of 
the young culm in the cases observed, and partly enclosed on the 
Sides by the equitant leaf blade. Perithecia large, 200-300 » in 
diameter, oval or obovate, projecting above the stroma but little 
y a small conical apex producing a slight unevenness of the sur- 
face. Ascj large, 200-250 X 15-20 #, tapering each way to slen- 
der ends, more strongly so at the base, so that they appear 
oblanceolate in side view. Spores very numerous, several hun- 
dred, narrowly apiculate, 15-25 X .5—.8 #, fusoid, straight or — 
slightly curved. On Paspalum leve. Auburn, Ala., collected by
