keep the two apart as distinct species, although both authors ad- 

 mit that, perhaps, the character of colored or colorless appendages 

 is variable. As a matter of fact, as Burrill (60) has pointed out, 

 many of the specimens in the exsiccati quoted by Winter as be-

An 



amination of specimens named E. Martii in herbaria shows at once 

 that in the forms of the present species, no satisfactory systematic 

 character exists in the absence or presence of color in the ap- 

 pendages, as a complete series of connecting links occurs, often, 

 even in specimens on the same plant, as may be seen in some ex- 

 amples on Lupinus. In many cases, though not in all, the ab- 

 sence of color is dependent merely on the age of the specimen as 

 at full maturity colorless appendages frequently become dark 

 brown. E. Martii, therefore, I think, may be safely considered a 



synonym of the present species. 



Oudemans (263) has attempted to separate certain forms of 



E. polygoni by the number of spores in the ascus : E. umhdli- 



ferarum on plants belonging to the Umbelliferae [e. g., An- 



thriscus, Heradcum) is stated to have 3-4 spores ; E. communis 



and E. 



Hyp 



These 



characters, however, altogether fail, and it need only be mentioned 



Hj'p 



containing only 3 spores, while 3-6 spores occur frequently in 

 soeclmens on Heradcum, etc. It will certainly be admitted by 



dealing with sufficient material of E. polygom that the 



anv one 



of E. 



number of spores varies from 3-8 in this species. 



E mnbdliferarum {E. herachi) is generally separated, how- 

 ever, not by the number of spores, but by the shape ofthe con.dia. 

 De Bary first pointed out this character when founding the species, 

 describing the conldia of E. communis as " ellipsoidea" and those 



_ llifcrarum (on Angelica, Chacrophylban, Anthriscus, 



Pastinaca, Falcaria and Heradcum) as " exacte cylindrica" ; 

 further remarking " dass diese Art E umhdliferarum von E 

 communis durch die Perithecien kaum verschieden 1st. Dagegen 1st 

 sie ausgezeichnet durch die Form der Conidien, welche genau 

 walzenformig, an beiden Enden flach, und mindestens (dock mcht 

 immer) sehr langgestreckt sind. Bei den vorher genannten Arten
