SPHAERELLA STENOSPORA E. & E. 
On dead stems of Sphaeralcea? northern Colorado, July, 
1897. (Baker, no. 413.) 
Perithecia erumpent, abundant, thickly scattered over the 
stems, 100-150y diam., perforated above; asci oblong, 45-55% 
10-I5 w, short-stipitate, often swollen on one side towards the 
base; sporidia biseriate, oblong-fusoid, uniseptate, scarcely or not 
at all constricted, 14-16 3-4 [bs 
This comes near S. spinarum Awd., but besides the peculiar 
habitat of that species, the sporidia in the fig. in Rab. Mycol. Eur. 
are represented as distinctly curved, while in the present species 
they are straight. S. Vincetoxici Sacc. has sporidia oblong-clavu- 
late. 
SPHAERELLA (DERMATOSTROMA) FRIGIDA E, & E. 
On bleached limbs and weather-beaten wood, San Juan 
Mountains, Colo., July, 1897. (Bethel, no. 361.) 
Perithecia globose, subastomous, black, membranous, 100— 
110 » diam., seated on a thin white membrane overspreading the 
surface of the host; asci clavate-cylindrical, 35-40% 8-10 pt, sub- 
sessile, aparaphysate, 8-spored; sporidia biseriate, fusoid-oblong, 
uniseptate and slightly constricted, straight or very slightly curved, 
obtuse, 12-15 X314-4% w, smoky-hyaline. 
Differs from the usual type of Sphaerel/a in the membranous 
stroma. 
LEPTOSPHAERIA MICROSPORA E. & E. 
On dead stems of Lespedeza capitata, London, Canada, 
August, 1897. ( Dearness, no. 2474.) 
Perithecia scattered or loosely gregarious, subcuticular, de- 
" pressed-globose; 150-250 » diam., subcollapsing, with a papilliform 
ostiolum ; asci clavate-cylindrical, sessile, paraphysate, 5 5-60 7- 
8/4; sporidia subbiseriate, narrow-elliptical, 1-3-septate, slightly 
constricted, 10-12 3-34 pu. 
The sporidia are oftener only 1-septate, in this respect ap- 
Proaching Didymosphaeria.
