[Von. IV, No. 7, 
ostiolum is at first very minutely papilliform but soon disappears, leaving 
the perithecia minutely perforated. This seems nearest allied to T. 
■pruniformis (Nyl.), but is smaller in all its parts and lacks the conoid- 
acute ostiolum. 
Lophiostoma excipuliforme, Fr., var. Abietis, E. & E.—On 
Abies; Cazenovia, N. Y., October, 1887. Prof. L. M. Underwood and O. 
F. Cook. Differs from the forms on bark of deciduous trees in its larger 
(00—75 x 12—16 p) sporidia and its rather narrower ostiolum. 
LopmosTOMA Montaniense, E. & E.—On dead stems of Clematis 
liaustifolia , Montana, February, 1888. F. W. Anderson, No. 134. Peri¬ 
thecia scattered or subseriate, erumpent-superficial, hemispherical, 4— £ 
cm. in diameter, rough, with a tuberculiform ostiolum pierced with 
a slightly elongated opening ; asci cylindrical, 100—112x7—8/^- (p. sp.) 
with filiform paraphyses ; sporidia uniseriate, elliptical, very slightly 
curved, constricted in the middle, 3-septate, the two middle cells brown, 
the terminal ones hyaline and bearing a straight, hyaline bristle 0—8 p 
long. The sporidia resemble those of a Pestulozzia. 
Lophiostoma Pruni, E. & E.—On Primus serotina , Lyndonville, N. 
Y., April, 1888. Dr. C. E. Fairman. Gregarious; perithecia sunk in the 
wood, i— i mm. in diameter; ostiola erumpent through the bark and 
strongly compressed; asci clavate-cylindrical, 80—90 x 8—9 with abun¬ 
dant paraphyses ; sporidia uniseriate, mostly four in an ascus, oblong, 
rounded at the ends, brown, 3-septate and constricted at the septa, a 
little narrower at the lower end, 18—22 x 6—8 p. This can hardly be L. 
acervatum , Karst., which has the perithecia erumpent in small clusters 
(csespites minutos) and sporidia scarcely constricted. 
Pleospora lactucicola, E. & E.—On decaying stems of Lactuca 
Canadensis , Newfield, N. J., June, 1878. Perithecia scattered, suberum- 
pent, depressed-hemispheric, 175—200 P in diameter; ostiolum papilli¬ 
form ; asci clavatc-cylindrieal, 90—100 x 10—12 p ; sporidia obliquely 
1-seriate or rarely subbiseriate above, oblong, slightly constricted, 3-sep- 
tate with each of the middle cells divided by a longitudinal septum, ends 
subacute and suboblique, 14—16 x 0—7 p. Allied to P. Bardance , Niessl., 
but compared with the specimens of that species in Linhart’s Fungi 
Ilungarici, No. 168, the perithecia are smaller and the sporidia also 
smaller and darker colored. Spbceria Lactucarum , Schw., is said to grow 
in cinereous spots. 
Leptosph^eria Tini, E. & E.—On leaves of Viburnum Tinus , La¬ 
fayette, La., December, 1887. Rev. A. B. Langlois, N<>. 1143 (in part). 
Maculicolous and amphigenous on large cinereous spots, with a narrow 
reddish-purple border. These spots or dead places often occupy the 
margin along one side or the apex of the leaf, 2—3 cm. in diameter; 
perithecia punctiform, ’ minute, innate, the black, subacute apex alone 
being visible ; asci oblong-cylindrical, subsessile, with filiform paraphy¬ 
ses, 40—50 x 7 p ; sporidia biseriate, fusoid, yellowish, slightly curved, 
faintly 3-septate, 14—10 x 3 p.
