This exceedingly abundant and widely occurring species is 

 doubtless to be found on other hosts in this State besides those 

 enumerated above. Although widely variable it is usually 

 easily recognized by its short dark appendages and numerous 

 two-spored asci. It is usually known as E. lamprocarpa.^ Lev. 

 Winter, however (Die Pilze, II., p. 33), adopts De Candolle's 

 name of E. cichoracearum, and according to the law of priority 

 this seems to be correct. 



The forms on various Labiatce are often included here, but 

 they differ in having lobed haustoria on the mycelium threads. 

 On the various species of Verbena the haustoria are smooth and 

 rounded as in the forms on Comimsitai.
