60 TWENTY-NINTH REPORT ON THE STATE MUSEUM. 
is at first olive-brown in color, but at length black spots appear upon 
it. These gradually enlarge until the whole surface becomes black. 
With this change in the color of the subiculum, the perithecia appear, 
but they do not, apparently, perfect their spores until the following 
spring, spore-bearing specimens having been found in May. The 
affected leaves adhere to the brauch during the winter and the early 
part of the following summer. These dry leaves, when seen among 
the surrounding green leaves that put forth before these have fallen, 
together with the drooping branch that bears them, are deceptively 
imitative of dead leaves on a branch that has been broken down but 
still adheres by a shred to the parent trunk. The young fungus 
commences its growth before the old one of the previous year has 
disappeared. I have taken from the same tree, at the same time, old 
leaves bearing the mature Spheria, and young leaves bearing the 
subiculum and young perithecia of the succeeding crop. The fungus 
does not appear to kill the branch it attacks. 
As Schweinitz does not describe the fruit of this fungus I subjoin 
the following description of its characters : 
Asci cylindrical; spores uniseriate, abruptly narrowed at one end 
and divided by an obscure septum into two very unequal parts, color- 
less, .0004—.0005’ long. 
This fungus is manifestly closely allied to Sphaeria morbosa, which 
some European mycologists have referred to the genus Cucurbitarza, 
but as the erumpent character of the Cucurbitarie is not present in 
S. Collinsii, the species is left where Schweinitz placed it. 
SpH=RIA (VILLos#) cHsarrata C. & P. n. sp. 
Perithecia gregarions, about .012’ in diameter, subglobose, papillate, 
black, shining, beset with scattered erect rigid septate black hairs; 
asci cylindrical or clavate; spores biseriate, narrowly fusiform, five 
to seven-septate, greenish, .0015—.0017 long, each cell nucleate. 
Decaying wood. Portville. September. 
Sprazria (VitLos#) Leontna C. & P. n. sp. 
Perithecia subconfluent or rarely scattered, dark-brown, oval, 
covered with a short thick tawny-orange tomentum, the papillate 
apex naked; asci clavate or cylindrical; spores biseriate, lanceolate, 
uniseptate, constricted, at length triseptate, brown, .0014—.0015' long; 
paraphyses slender, filiform. 
Cut surface of wood. Portville. September. 
SpHaria Frmeri Pers. 
Horse dung. Sandlake. July. 
SPH#ARIA OBDUCENS 7. 
Ash branches. Bethlehem. June.
