.67 
pent, minute, (50-60 p) , pierced above. Asci oblong, subsessile, 
rather abruptly narrowed at the ends, 30-35x6-7 p. Sporidia 
biseriate, fusoid-oblong, 3-guttulate, hyaline, 10-12x3-3^ p. 
Laestadia ari E. & E.—On living leaves of Arum arifolium. 
Spots subcircular, dark gray above, deep brown below, 1 cm. 
diam., with a narrow darker border; perithecia epiphyllous, abund¬ 
ant, evenly and thickly scattered over the central portion of the 
spots, ioo-iio p diam., pierced above, semi-erumpent. Asci ob¬ 
long-cylindrical, short-stipitate, 40-50x7-8 p, paraphyses rudi¬ 
mentary or wanting. Sporidia biseriate, subnavicular, 2-3- 
nucleate, hyaline, obtuse, 8-10X3J-4-J p. 
Vermicularia trichella Fr. is found in a narrow belt just 
within the margin of the spots. 
Sphaerella yuccae E. & E.—On leaves of Yucca filamen- 
tosa. 
Perithecia evenly scattered on the dead leaves, subcuticular, 
slightly raising the epidermis, at length more or less collapsing, 
small (110-120 p). Asci clavate-cylindrical, short-stipitate, 
45 " 55 XI °' 12 /JL - Sporidia biseriate, short, oblong-fusoid, 12-15X 
4-5 p , uniseptate but not perceptibly constricted. 
Didymella ricini E. & E.—Proc. Phil. Acad. 421. 1895. 
Prof. Carver sends this on dead shoots of Ailanthus glandulosa; 
the asci 45-50x10-12 p, spor. oblong-elliptical, obtuse, yellowish- 
hyaline, scarcely curved, 12-15x5-6 p ; on stems of Mucuna utilis, 
asci 40-45x8-10 a, spor. oblong-fusoid, distinctly curved, 12-15X 
4-5 \ p , yellowish-hyaline, becoming uniseptate; on Hibiscus 
esculentus, asci 50x10 u, spor. curved, yellowish, 12-15x4-4^- u, 
2-3 guttulate (becoming unseptate). 
The perithecia in all these collapse. This is closely allied 
to D. sphaerellula (Pk.) and D. fuschiae (Ck. & Hark.). 
Physalospora vagans E. & E.—On dead, bleached canes of 
Rubus strigosus. 
Perithecia scattered, singly or 3-5 subconfluent, membrana¬ 
ceous, of rather coarse cellular structure, black, pierced above, 
100-200 p diam., raising the cuticle into little pustules which, 
especially over the clustered perithecia, are ruptured by a narrow 
cleft. Asci clavate-cylindrical, 110-200x12-20 p, short,stipitate 
and obscurely paraphysate. Sporidia uniseriate in the narrower 
asci, biseriate in the broader, elliptical, 12-20x8-12 p hyaline, 
The asci soon collapse so that the sporidia bulge out all round 
like a bag stuffed full of apples. Many of the perithecia, espe¬ 
cially the scattered, single ones, contain only stylospores narrow- 
elliptical, hyaline, 15-20x7-8 p, on basidia 12-20x1^ p. 
Physalospora obtusa (Schw.) Cke.—On Rubus villosus, 
has longer, narrower sporidia 35-40x9 p . This occurs also on the 
following hosts : on dead steins of spiraea—asci 150x20-25 u, spor.
