perithecium, usually fasciculate by irregularly bending near the base, 

 and clustered towards one side, very distinct from the mycelium. Asci 

 3-5. pedicellate. Sporidia 4-6, 22-30 // long.

This is here included solely upon the authority given, and appar- 

 ently upon one collection. In Europe the fungus is common on the 

 >ame host, and as this is abundant in cultivation with us, it is alto- 

 gether probable that this parasite may be frequently found. It is very 

 distinct from those forms of E. communis with long appendages, as on 

 Clematis. These latter have indeed been referred to E. tort His, 

 evidently by mistake.

A mphigeiious. Mycelium abundant, persistent, haustoria rounded, 

 not lobed. Perithecia variable ; appendages numerous, mostly short, 

 1-2 times the diameter of the perithecium, hyaline or mostly colored, 

 much bent and interwoven with the mycelium. Asci variable, mostty 

 numerous, 4 or 5 to 20. Sporidia large, quite uniformly 2. but occa- 

 sionally varying to 3, or even 4 (on Bigelovia 5 or 6).
