Dead branches of Robinia

Dead barberry.

Dead maple.

Dead buttonwood.

Decaying wood. 



851. SPH^ERIA, Hall. 



Modern mycologists have divided the old genus SphtzHa into many smaller 

 genera with narrower limits. Most of our species fall readily enough into these 

 modern genera, but in a few instances these generic limits are not wholly satis- 

 factory, and will need some modification. So far as possible I have grouped our 

 species with reference to these modern genera. C. H. P.

2477. S. monosperma, Pk. Reg. Rep. 28, p. 79. 



Decaying wood. There is a genus of lichens, Sporopodium, 

 Mont., whose species have spores similar to those found in 

 this Sphceria, but in other respects the plants are quite 

 unlike. 



2478. S. exilis, A. and S. Reg. Rep. 29, p. 61. 



Decaying wood. The bristly perithecia separate this species 

 from the genus Ccelosphceria. Perhaps the more comprehen- 

 sive genus Nitschkia might include it. 



2479. S. morbosa, Schw. Reg. Rep. 23, p. 64. 



Living branches of plum and cherry trees. This species has 

 been referred by some botanists to the genus Cucurbitaria, 

 but it does not well agree with the characters of that genus. 

 It comes very near to Dimerosporium, Fckl., from which its 

 cylindrical (not ovoid) asci separate it. 



2480. S. fraxicola, Schw. Reg. Rep. 25, p. 105. 



Fallen ash leaves.
