Myrmaecium fraxineum E. & E. On dead limbs of Frax- 
inus viridis (?). River Forest, Ill. Oct. 1902. (E. T. & S. A. 
Harper, 599.) Com. E. Bartholomew. 
Perithecia ovate-elliptical, 100-125// diam., slightly sunk at 
first in a soft, whitish stroma, soon erumpent in densely crowded 
clusters, 3-1^ mm. across, flattened above and erumpent through 
the epidermis, black outside, white within. Asci cylindrical, p. 
sp. about 75x8-10 u , paraphyses, if any, very evanescent. Spo- 
ridia uniseriate or biseriate above, ovoid, hyaline with a distinct 
olivaceous tint, uniseptate and more or less constricted at the 
septum, 12-14x5-6/*. 
This comes very near M. endoleucum Sacc. and may not be 
distinct from that species, the only difiference being in the suboli- 
vaceous, constricted sporidia. 
Diatrypella vetusta E. & E. On a decorticated, partly de¬ 
cayed stick lying on the ground, River Forest, Ill. Oct. 1902. 
(E. T. & S. A. Harper, No. 596.) Comm. E. Bartholomew. 
Stromata thickly scattered, erumpent-superficial, j-i-J mm. 
diam., black, uneven above from the slightly prominent, obtuse, 
smooth ostiola. Asci clavate-cylindrical, 75-80x8-10/*, para¬ 
physes obscure. Sporidia allantoid, yellowish, crowded in the 
asci, slightly curved ends obtuse. 
A faint but deeply penetrating black line surrounds the part 
occupied by the fungus. 
Melanopsamma utahensis E. & E. On dead stems of 
Actaea rubra, Salt Lake, Utah. Aug. 1903. (A. O. Garnett, No. 
287.) 
Perithecia gregarious, at first covered by the cuticle, soon 
superficial, subglobose, becoming slightly depressed or flattened 
at the top, about \ mm. diam. Asci clavate cylindrical, narrowed 
at the base into a short stipe, 75 x 12 \,u , Paraphyses evanescent. 
Sporidia subbiseriate, clavate oblong, hyaline, uniseptate, con¬ 
stricted near the middle, slightly curved, 25-30 x 6-7/*, lower cell 
narrower. 
M. caulicola Rehm on Salvia is the (only ?) other caulico- 
lous species described. The conic-papilliform ostiolum with a 
round opening will separate it from Lophiosphaeria. 
Cercospora platanicola E. & E., Jour. Mycol. 3:17. Feb. 
1887. 
Well matured specimens of this species collected at Mingo, 
W. Va., Sept. 1903, have the conidia larger, 30-55x4-5/*. and 
smoky hyaline. The spots become confluent and the entire leaf 
becomes brown and dead.
