E. labiatarum, Chev. (Flora Paris, III., p. 380). 



Ampliigenous. Mycelium abundant, persistent, haustoria 

 of the mycelial threads lobed; perithecia somewhat aggregated; 

 appendages numerous, short, flexuous, colored, interwoven with 

 the mycelium; asci numerous, often 12 or more; spores 2, 

 mostly formed late. 



On Stachys palustris: Henry, Sept. 28, 1705. Stachys 

 sps.: Stephenson, Sept. 13, 5812. Teucrium Canadense: La- 

 Salle, Sept. 29, 6239. Scutellaria parvula : Lee, Sept. 27, 6208. 

 Scutellaria lateriflora: McLean, Sept. 6 (Seymour). 



This can scarcely be separated from E. cichoracearum by 

 the characters of the perithecia, but the difference in the haus- 

 toria, first pointed out by De Bary (Morph. und Phys. der Pilze, 

 IIL, p. 49), can be observed by first soaking a portion of the 

 leaf in caustic potash and then removing a little of the myce- 

 lium to the slide. In our specimens the perithecia and append- 

 ages are rather lighter colored than is usual in E. cichora- 

 cearum.

Amphigenous. Mycelium abundant, persistent, haustoria 

 rounded, not lobed; perithecia variable; appendages numerous, 

 mostly short, 1-2 times the diameter of the perithecium, col- 

 ored, much flexed and interwoven with the mycelium- asci
