slightly sunk in the surface of the wood; ostiolum papilliform ; 
asci cylindrical, short-stipitate, paraphysate, 8-spored; sporidia 
uniseriate, elliptical, compressed, 6-9X 5—6y and about 3%y thick. 
The sporidia are obtusely rounded at the ends when viewed in 
front, but subacute when seen edgewise. 
AAMPHISPHAERIA MELANTERA E. & E. 
On bark of Quercus undulata, Deansbury, Colo., Apr., 1897. 
(E. Bethel, no. 230.) 
Perithecia erumpent-superficial, ovate-globose, black, 14-34 
mm. diam., scattered; ostiolum obscure, at length perforated ; 
asci oblong-cylindrical, subsessile, 100-110 20-22y, with abun- 
dant filiform paraphyses; sporidia biseriate, oblong, uniseptate, 
strongly constricted at the septum so that the two cells easily sepa- 
rate, the lower cell mostly narrower, brown, 20-35 X 12-15. 
A. Querceti Cke. & Mass., has larger perithecia and unise- 
riate smaller sporidia only slightly constricted. 
TEICHOSPORA POPULINA E. & E. 
On decorticated weather-beaten limbs of Populus monilifera, 
Rooks Co., Kansas. (Bartholomew, 2388.) 
Perithecia scattered, semierumpent, subglobose, about 4% mm. 
diam., partly covered by the loosened fibers of the wood ; ostio- 
lum papilliform ; asci cylindrical, subsessile, paraphysate, 8-spored, 
I110-120X8-10; ‘sporidia uniseriate, ovate-elliptical, 3-5-sep- 
tate, constricted at the septa, more strongly so at the middle one, 
brown, 15-22X7-8y, the inner cells divided by a longitudinal 
septum. 
LOPHIOSPHAERA RHODOSPORA E. & E. 
On the inner surface of cast-off bark, Ohio. (Morgan, no. 
1162.) 
Perithecia erumpent-superficial, gregarious, ovate-conical, later- 
ally compressed, 200-250 diam., submembranous, ostiolum nar- 
row, subcompressed or simply papillate, soon perforated; asci 
clavate-cylindrical, 70-75 X 10-12 (paraphysate) ? 8-spored, short- 
stipitate; sporidia uniseriate and oblique or biseriate, ovoid- 
elliptical, rosy-hyaline, uniseptate, scarcely constricted, 12- 
14X%5-6p. 
The mass of sporidia is distinctly rose-colored, giving by trans- 
lucence the same color to the young perithecia which, however, 
soon beccme black. On account of the slightly compressed 
ostiolum this might be referred to Melanopsamma. The material 
was too scanty to decide conclusively. —
