Diatrype nigerrima E. & E.— On bark of Vitis, Glencoe, 
Ill. June 1903. (E. T. & S. A. Harper, 904). 
Stroma superficial, effused, tubercular-roughened, black out¬ 
side, white within, tubercles i-i-J mm. diam. or by confluence 
-J-i cm. Perithecia monostichous, globose or ovoid, crowded, 
small, mm. narrowed above into short neck terminated by 
the minute, subglobose ostiola which (8-10 together) rise through 
the surface of the stroma in little conical projections scattered in¬ 
discriminately over the stroma, both on and between the tubercles 
and much resembling small, black perithecia cleft across the top 
by a narrow slit through which the erumpent tuft of ostiola arise. 
Asci lanceolate, finally rounded at the top, p. sp. 25 x 3-4/A. Spo- 
ridia 8 in an ascus, allantoid, smoky-hyaline, slightly curved, 
8-10 x I -2/a. 
Valsaria magnoliae E. & E.— On dead limbs of Magnolia 
(cult.), London, Canada, Dec. 1903. (J. Dearness, 2082). 
Stroma cortical, effused, blackening the inner bark. Perithe¬ 
cia sunk in the inner bark, then semi-erumpent, white inside, about 
J mm. diam. scattered irregularly, or valsiformly aggregated, or 
seriate, soon deciduous. Asci cylindrical, subsessile, paraphysate, 
80-100 x 10-12 /a with the sporidia obliquely uniseriate or 100-150 
/a with sporidia lying end to end. Sporidia uniseriate, oblong- 
elliptical, 18-23 x 8-10 /a, more or less constricted in the middle, 
brown. 
This was accompanied by Sphaeropsis magnoliae E. & D. 
Phyllachora cinerea- E. & E.— On dead branches of Ca- 
talpa, London, Canada, Nov. 1903. (Dearness, 2087). 
Stromata scattered, seated on the inner bark which is uni¬ 
formly blackened, orbicular, mm. diam. or oblong |x i| mm., 
cinereous within, disk fusco-cinereous, erumpent, flat, surrounded 
by the ruptured margin of the epidermis. Asci clavate-cylindrical, 
80-100 x 12-15 /a, paraphysate. Sporidia biseriate, ovate-elliptical, 
hyaline 12-15 x 5-7/1, continuous. 
Most of the stromata contain only stylospores 8-10 x 4-5/1, 
hyaline, continuous, oblong-elliptical or ovate-elliptical and then 
the fungus does not differ appreciably from Phoma diatrypea (C. 
& E.) Sacc. which is found on Chiononthus. 
There are no true perithecia, the stroma containing merely 
ascigerous or sporuliferous cavities. 
Peziza hainesii Ell., Bull. Torr. Bot. Club, is hardly dis¬ 
tinct from P. semitosta B. & C., the only difference being the color 
of the hymenium.
