89) is quite distinct 



and is well worthy of varietal if indeed not of specific rank. The 

 stroma is short, normally 1—2 mm. long (by confluence 1 cm. or 

 more) but very much thickened, often seeming nearly globular. 

 The perithecial cavities and osteola are much as in the type. The 

 name for this latter fungus may be tentatively written as Ophio- 

 dotJiis atramentosa pilnlaeformis (B. & C). 



Ophiodothis atramentosa Aristidae (Atk.) 



DotJiicldoe Aristidae Atk. Bull. Torr. Club, 21 : 24.

 June, 1895. P. H. Rolfs, no. 44. 



This was given specific rank by Atkinson, and perhaps justly 

 so, but as the following variety is intermediate in character 



■ 



between this and the type it seems best, for the present, to con- 

 sider all of these forms as varieties, especially as they are so closely 



1 



alike in their ascospores and asci. The distinguishing features of 

 this form are the rougher more prominent ostioles and the inter- 

 rupted or broken character of the fertile part of the stroma. 



Ophiodothis atramentosa Cyperi var. nov. 



Stroma interrupted, being formed of a thin sterile and of ele- 

 vated fertile portions, the fertile tracts 1-2 mm. long by half as 

 wide, perithecial cavities and ostioles as in the type.

This seems to be the first time that this interesting fungus has 

 been taken with well-developed asci and ascospores ; at least no 

 description of these bodies has been published. The conidial form 

 was distributed by Ellis, from New Jersey, as N. A. F. no. 33 3 2. 

 The Flc>rida material agrees closely with this in the character 

 of the distortions produced on the host and in general appearance, 

 though the conidia seem slightly larger and broader. This coni- 

 dial stage is referable to the form genus Psilospora, but it seems 

 never to have been given a specific name under that genus.
