118. Byssonectria rosella, Ck. Hark, (fi’ev. 1. c. On dead 
grass, California. Harkness, No. 2441. 
Delicate, effused, with a rose-colored tint; liyplne creeping, inter¬ 
woven, with the minute, obscure perithecia scattered on it; conidia 
lunate, like those of Fusarium, acute at each end, 5-septate, mostly nod¬ 
ulose and hyaline, 40x 5—6 /^-. Unfortunately, in an immature condition. 
Gen. IX, Dialonectria, Sacc. (in part).— Perithecia free, super¬ 
ficial, gregarious or scattered, carnose, glabrous, bright-colored. 
A. Sporidia continuous. {JSfectriella.) 
119. Dialonectria vulpina, Ck. Grev. XII, p. 83. Ell. N. Am. 
Fungi, 774. On rotten wood of maple and apple tree. New Jersey and 
Pennsylvania. 
Perithecia gregarious or scattered, light yellow, about one half 
millim. in diam., globose at first and thinly clothed with short, erect, 
subglandular hairs and subfurfuraceous, finally collapsing so as to be 
easily mistaken for a Peziza; asci clavate-cylindrical, 35—45 x 6—7 !>-, 
8-spored ; sporidia either biseriate, 8—11 x 3—3^ p- or obliquely imiseri- 
ate, 8—12 x 4—44, elliptical or oblong-elliptical, 2—4-nucleate, with some 
sporidia in old specimens, becoming uniseptate. 
120. Dialonectria mycetophila, Pk. 26th Rep. N. Y. State 
Mus., p. 85. On decaying fungi. New Scotland, N. Y. (Peck). 
Perithecia crowded or scattered, minute, smooth, subglobose, pale 
yellow when young, then pinkish-ochre; ostiola minute, papillate, 
distinct, darker-colored; asci siibclavate; sporidia oblong, simple, 
12—13 X 4 pP 
B. Sporidia uniseptate. [Eu-Dialonectria.) 
(a.) Growing on wood or hark. 
121. Dialonectria sanouinea (Sibth.) Fr. Sum. Veg. Scand., 
p. 388. Fr. S. M. II, p. 453. 
Perithecia scattered, adnate, ovoid, rarely subsplneroid; ostiolum 
papilliform, smooth, blood-red, rarely flesh-color, soft, about 180 !>■ in 
diam.; asci cylindrical, 50—60 x 5—6 !>■, 8-spored; sporidia obliquely 
uniseriate, elliptical or subelliptical, unequally 1-septate, slightly con¬ 
stricted, hyaline or with slight tinge of rose-color, 7—10 x 4—5 Common 
on moist decaying wood and bark of various deciduous trees. Saccardo 
properly observes that this scarcely differs from N. episphceria, Fr., except 
in its ovoid, scarcely collapsing perithecia and its less distinctly septate 
sporidia. 
122. Dialonectria Peziz.e (Tode.) Fr. Summ. Veg. Scand., p. 
388. On decaying wood and bark. South Carolina (Ravenel), Massa¬ 
chusetts (Murray). See Grev. IV, p. 16. 
Perithecia gregarious, superficial, spherical, becoming concave by 
collapsing, subpapillate, reddish-orange, fading at length, subpilose at 
base, soft, about one third millim. in diam.; asci very shortly pedicellate, 
cylindrical or clavate-cylindrical, 80—90 x 8—10 !>■ when young, subcris- 
tate at the apex, 8-spored; sporidia subimiseriate, elliptical, obtuse at 
each end, uniseptate, but not consti’icted, each cell nucleate, hyaline, 
10-14 X 5—6 !'■.
