ends rounded (fiisoid-oblong), often with a distinct j^ellow-brown shade. 
The wood just below the surface assumes a uniform purplish-red color. 
This might, perhaps, be considered a var. of Lophiostoma pulveraceum, 
Sacc., but differs in the stained matrix, larger perithecia and deciduous 
ostiola. 
Lophiostoma subcollapsa, E. & E. — On outer bark of living 
Nyssa multijiora, Newfield, N. J. June, 1886. Perithecia cartilagino- 
membranaceous, black, globose, f—1 millim. in diam., buried in the sub¬ 
stance of bark, the epidermis slightly elevated and blackened over them 
and pierced by the papilliform ostiolum, which finally collapses; 
asci clavate-cylindrical, about loO x 12 /^, with abundant paraphyses; 
sporidia obliquely 1-seriate or more or less distinctly biseriate above, ob¬ 
long-elliptical, 20—26 X 8—10 y or regularly elliptical, 20—22 x 12—15 
hyaline at first becoming brown and 3—7-septate, but not constricted at 
the septa. The sporidia are sometimes a little curved, or at least more 
prominent on one side. Apparently allied to L. obtectum, Pk., and ap¬ 
proaching Massaria. The ostiolum is quite inconspicuous and only 
slightly prominent. Sometimes one or two of the cells of the sporidia is 
divided by a longitudinal septum. 
Diaporthe Kellermanniama, Winter.—On decaying culms of 
Zea Mays. June. Langlois, 494. Stroma extending continuously tor 
several inches, or in narrow strips and irregular patches, circumscribed 
by a black line and surface of the matrix also blackened; perithecia 
scattered or subcsespitose, sunk in the substance of the culm, i—^ millim. 
in diam., their long (1 millim.), rather crooked black ostiola projecting ; 
asci lanceolate, about 40 x 7—8 ; sporidia biseriate, oblong-fusoid, 
4-nucleate and yellowish, becoming constricted and uniseptate, ends 
rather obtusely pointed, 7—10 x 3 h-.

In the published description o| this species in Bull. Torr. Bot. Club, 
X, p. 49. There is nothing said of any ostiolum, and there is said to be 
no stroma (stroma nullum ” ), but we believe this is, nevertheless, the 
species there meant. / 
Sph^ria (Zigncella) suBvisTiTA, E. & E.—On dry, bleached roots 
of Faccmewni, Newfield, X. J., May, 1886. Perithecia seated on the bare 
wood or on the bark, with the base sunk in the matrix, ovate-conic, one 
sixth to one fourth millim. in diam. and one half millim. or more high, 
black, rough, except the smooth, sub-shining, short-cylindrical or sub- 
conical, broadly perforated, sub-truncate ostiolum ; asci clavate-cylin¬ 
drical, 50 X 6—7 /^, with filiform paraphyses and a slender, stipitate base ; 
sporidia fusiform, yellowish-hfaline, slightly curved, 3-septate and con¬ 
stricted slightly at the middle septum, 12—15 x 2i—3 /^, crowded-biseri- 
ate. The sporidia are much tlie same as in Sphceria llendersoni, Ell., ex¬ 
cept in having the ends slightly curved, but in that species the perithecia 
are depressed and subcuticular and subastomous. Melanomma conica^ 
Fckl., has much larger sporid/a (28 x 4 y).
