133. Dialonectria Galii, Plow. *& Hark. Trans. Cal. Acad. Sci., 
1884, p. 26. 
Perithecia scattered, immersed, then erumpent, obtuse, pale-red; 
asci cylindrical, very delicate, 60 x 5—8 /-'•; sporidia eight, uniseriate, 
uniseptate, pale straw-color, oblong-oval, with bluntly-pointed ends. On 
Galium trifolium, California. Harkness. 
134. Dialonectria Peponuji (B. & C.) Grev. IV, p. 16. Nectria 
perpusilla, B. & C. Rav. Pung. Car. Exsic. IV, p. 51. On dead gourds 
and on tomato. So. Car. Ravenel. 
Very small, scattered, scarlet; sporidia oblong, uniseptate. It looks 
at lirst sight as if seated on a smooth, white mycelium, but it is only the 
external coat of the gourd. Var. aurelia (1. c.), having sporidia continu¬ 
ous, is probably only the immature state of the same thing. 
We add the following from an examination of the specimen in 
Ravenel’s Exsiccati, above quoted : Perithecia depressed globose, 100—120 
in diam., ostiolum broad, papillate ; asci clavate-cylindrical, 35—40 x 
5—6 /^-; sporidia not well matured, but apparently about 10 k 3i p-. 
135. Dialonectria conigena (E. & E.) Bull. Torr. Bot. Club X, 
p. 77. On an old decaying cone of Magnolia glauca, Newfield, N. J., 
October. 
Minute, membranaceous, smooth, orange yellow, lighter and collaps¬ 
ing when dry ; asci about 50 x 7 P ; sporidia uniseriate or partially 
biseriate above, acutely elliptical, 2-nucleate, becoming uniseptate, 7—8 x 
3—34 P ; ostiolum papilliform, minute; perithecia with a few weak, 
white, radiating hairs at the base. Differs from N. vulpina, Cke., in its 
habitat, smaller and paler perithecia and rather narrower and more 
acute sporidia. 
(c.) Growing on cryptogamous plants. 
136. Dialonectria EPISPH.ERIA (Tode.) Fr. Summ. Veg. Scand., 
p. 388. On various sphairiaceous fungi — Diatrype, Hypoxylon, Valsa, etc. 
common. 
Perithecia gregarious or scattered, superficial, subsphseroid, collapsing 
and frequently subcompressed, soft, smooth, blood-red, about 180 p in 
diam., with a papilliform ostiolum ; asci cylindrical, 50—60 x 5—6 p, 
8-spored; sporidia obliquely uniseriate, subellipsoid, rather unequally 
uniseptate, hyaline, slightly constricted, 7—10 x 4—5 p. 
137. Dialonectria filicina, Ck. & Hark. Grev. XII, p. 101. “On 
stipes of tree fern, California (Harkness.) 
“Scattered or gregarious, orange-colored ; perithecia obovate,smootli. 
glabrous, subshining, scarcely papillate ; asci cylindrical, 8-spored ; spo¬ 
ridia elliptico-cylindrical, obtuse at each end, hyaline, 8 x 24 Our 
specimens from Dr. Harkness have the asci about 40 x 5 \ sporidia 
mostly biseriate, 3—4-nucleate, becoming uniseptate, 7—10 x 24—3 p. 
C. Sjyoridia elongated, guttulate or septate. iCalonectria.)
