Perithecia gregarious or crowded, erumpen‘-superficial, globose- 
hemispherical, minutely roughened, 500-650 pin diameter, finally 
collapsing above; ostiolum black, conic-papilliform ; asci cla- 
vate-cylindrical, stipitate, paraphysate, 85-100 X 9-10 »:; sporidia 
overlapping, uniseriate, oblong-fusoid, sub-acute below, obtuse 
above, 3-septate, slightly constricted at the middle septum, hya- 
line at first, then pale yellow, generally with one cell (sometimes 
two cells) divided by a longitudinal septum, 15-20 X 6-8 4; 
stylospores in similar perithecia, oblong-elliptical, uniseptate, 
scarcely constricted, nearly hyaline, 6-8 X 3-3% p. 
MELANOMMA CUPULATA E. & E. 
On decorticated Salix, Mt. Paddo, Wash., alt. 7000 ft. 
(Suksdorf, no. 484.) - 
Perithecia scattered or gregarious, superficial, brownish-black, 
membranous, clothed with short (20-402) continuous 
spreading subundulate brown hairs, finally collapsing to cup- 
shaped, with a papilliform ostiolum. Where the perithecia stand 
close together the surface of the wood is often covered with a felt- 
like olive-black subiculum, formed of branching brown closely 
septate hyphae; asci clavate-cylindrical, 45-60 X 8», with in- 
distinct paraphyses ; sporidia biseriate, oblong-fusoid, pale brown, 
3-septate, not constricted, 10-12 X 3%4-4 p. : 
Closely allied to C. pilosel/a Karst., but perithecia collapsing 
and asci and sporidia somewhat smaller. 
LOPHIOTREMA FRAXINI E. & E. 
On decorticated Frazinus viridis, Rooks Co., Kansas, March 
30, 1896. (Bartholomew, no. 2101.) 
Perithecia scattered or gregarious, semi-emergent, depressed- 
spherical, brown, 400-500» in diameter; ostiolum variable, 
papilliform, compressed-conical, or extending % across the peri- 
thecium ; asci clavate-cylindrical, 85-90 10; sporidia biseri- 
ate, fusoid, acuminate, hyaline, 5- or more nucleate, becoming 
3- or more septate, scarcely constricted, 35-42 X 414-6 », mostly 
about 5 » thick. : 
L. Fontanesiae Pass. and L. Coryli H. Fabre have sporidia about 
the same as this, but differ otherwise. 
LopHIOTREMA OENOTHERAE E, & E. 
On dead stems of Ocnothera biennis, Newfield, N. J., Aug., 1895. 
Perithecia subgregarious or scattered, erumpent-superficial, 
minute (about 14 mm.), ovate-globose, with a narrow, but promi-
