DIDY3IELLA PROMTNENS, E. & E.—Oil dead herbaceous stems of 
Ambi'osia trifida. Langlois, No. 336. Perithecia erumpent-superficial, 
scattered, ovate-hemispheric, i millim. in diam., black, rough, except the 
prominent, tubercular-conic or short-cylindrical ostiolum ; asci clavate- 
cylindrical, subsessile, 40—45 x 6—7 with filiform paraphyses and eight 
subfusoid or subcymbiform, 1-septate, hyaline sporidia, 10—12 x 3—4 /^, 
slightly constricted at the septum. 
Diaporthe Gladioli, E. & E.—On dead stems of Gladiolus, Louis¬ 
iana, February, 1886. Langlois, No. 390. Perithecia sunk in the sub¬ 
stance of the stem just below the epidermis, which is blackened above 
them, forming elliptical, definitely limited spots 2—3 millim. long or, by 
confluence, 1 cm. or more; perithecia about i millim. in diam., tew, 
often only one or two in a spot, sometimes 6—8; asci (spore-bearing 
part) about 40 x 6—7 /^-, with a substipitate base ; sporidia biseriate, sub¬ 
fusoid, 7—10 X 2i/^, 2-nucleate, becoming 1-septate, hyaline. The osti- 
ola project like slender, black bristles about 1 millim. long, but are easily 
broken off. This is very different from Sphcerella minimcepiincta^ Ck., 
also on Gladiolus. 
Spu^rella Sapindi, E. & E.—On living leaves of Sapindus mar- 
ginatus, Missouri, July, 1886. B. T. Galloway. Perithecia epiphyllous, 
globose, prominent (i millim.), scattered, on roundish, definitely mar¬ 
gined, white spots, 3—4 millim. in diam.; asci oblong-cylindrical, 60 x 12 
p -; sporidia biseriate, subelliptical (a little narrower at one end), 1-septate 
and slightly constricted, 16 x 4 p. The conidial stage is a macrosporium 
on the same spots, with long, stipitate conidia and slender, septate hyphie. 
Spii^rella sabaligena, E & E.—On dead tips of leaves of Sabal 
Palmetto, April, 1886. Langlois, No. 426. Perithecia gregarious, 100—125/^ 
in diam., covered by the cinereous cuticle, which is scarcely ruptured, over 
them ; asci subovate. 22—25 x 12—15 P ; sporidia crowded, oblong-clav- 
ate, 1-septate, constricted at the septum, subhyaline, 10—12 x 3i—4 P. 
Sph^rella subcongregata, E. & E.—On peduncles of Erigeron 
salsiiginosiis, Mt. Paddo, Wash. Terr., alt., 6,000 to 7,000 ft., August, 
1885. VV. N. Suksdorf, No. 234. Perithecia gregarious or occasionally 
3— 6 collected in a cluster, erumpent and subsuperficial, ovate-globose, 
about i millim in diam., ostiolum acute ; asci oblong, 40—45 x 12—15 p, 
without paraphyses ; sporidia biseriate, oblong-cylindrical or clavate- 
oblong, subhyaline (yellowish), 18—23 x 3—4 p, or, in the clavate form, 
4— 5 P wide. Pleospora permunda, Ck., which appears to be common in 
the Rocky Mt. region, occurred on the same stem. 
Sph^rella smilacina, E. & E.—On dead stems of Smilax, New- 
field,N. J., May, 1886. Scattered, depres.sed, globose, one sixth millim. in 
diam., covered by the cuticle, which is blackened directly over the perithe¬ 
cia and barely pierced by the minute ostiolum ; asci oblong, sessile, about 
35 X 7 !>■; sporidia biseriate or crowded, hyaline, fusiform-oblong or clav- 
ate-oblong, 1-septate, 9—11 x2i ; perithecia entirely similar to theasciger- 
ous perithecia, only a little more prominent and mostly on bleached stems, 
contain stylospores, oblong or elliptical-oblong, hyaline, 2-nucleate, 1-sep¬ 
tate and slightly constricted, 7—8 x 3—34 p. Di2)lodina Smilacis, E. & E.
