130 
Perithecia scattered, subcuticular, 100-130 » in diameter, vis- 
ible through the epidermis which is slightly raised; asci clavate- 
cylindrical, 35-40 (p. sp. 25-30) X6-7 »; sporidia biseriate, ob- 
long, obtuse, nucleate, continuous, hyaline,9-12 X 3= 3-34». 
In L. Epilobii Wallr., the perithecia collapse and the sporidia 
are larger (13-17 X 3-4 1). 
DIDYMOSPHAERIA MAJOR E. & E. 
On decorticated wood of Rhus glabva, Rooks Co., Kansas, 
September, 1895. (Bartholomew, no. 1934.) 
Gregarious, covered by the blackened surface of the wood 
which is raised into pustules pierced by the papilliform ostiola; 
perithecia buried in the unchanged substance of the wood, about 
300, in diameter; asci cylindrical, 90-105 X 10-12 », short- 
stipitate, paraphysate, 8-spored; sporidia uniseriate, mostly ob- 
lique, oblong-elliptical, uniseptate, slightly-or not at all constricted, 
pale brown, obtuse, 12-18 X 7-8 p. 
Differs from D. rhoma E. & E. on the same host, in its larger 
asci and sporidia. 
DIDYMOSPHAERIA RHOINA E & E. 
On weather-beaten, decorticated limbs of Rhus glabra, Rooks 
Co., Kansas, September, 1895. (Bartholomew, no. 1935.) 
Perithecia gregarious, covered, ovate-globose, 350-450y in © 
diameter, with a conic-papilliform erumpent ostiolum; asci cylin- 
drical, short-stipitate, paraphysate, 60-70 X 6 y; sporidia uniseriate, 
elliptical, pale brown, scarcely constricted, 7-8 X 4-5 p. 
Differs from D. conoidea Nessl. in its rather smaller elliptical 
sporidia, and its rather smaller permanently covered perithecia. 
PHYSALOSPORA SUBERUMPENS E. & E. 
On bark of dead Eucalyptus globulus, California (McClatchie). 
Perithecia gregarious, at first covered by the pustuliform- 
elevated epidermis, then semi-erumpent, white inside, 4{-%{ mm. 
in diameter, the erumpent apex conic-hemispherical, crowned 
with the strongly papilliform or conic-papilliform ostiolum; asci 
broad, clavate-cylindrical, 80-100 X 18-20 »; sporidia irregularly 
crowded, elliptical or ovate-elliptical, hyaline, 18-21 Q-I1 p. 
Accompanied by a Sp/aeropsis in similar but rather larger peri- 
thecia, with oblong-elliptical brown sporules, 18-22 X 10-12 pe 
AMPHISPHAERIA SEPARANS E. & E. ; 
On old cottonwood shingle, Smith Co., Kansas, April, 1896.
