resemble. The form of the perithecia, size of the spores and 

 phyllogenous habitat are sufficient to set it apart as distinct from 

 that species. 



As to whether these plants occur on the living leaves no state- 

 ment is made by the collectors, but the leaves appear to have 

 been collected in the living condition and since the fungi which 

 they accompany are reported to be parasitic it is likely that the 

 Nectria also occurs on the leaves while living. Although accom- 

 panying Parodiella the plants do not seem to be parasitic on the 

 fungus, but since in the three specimens examined the Nectria 

 accompanies the Parodiella there may be a close relationship be- 

 tween the two fungi as well as between the fungi and the 

 leguminose host on which they occur. 



1 8. Nectria Brassicae Ellis & Sacc. 

 Michelia 2 : 374. 1881 



Perithecia scattered or gregarious, subconical, entire or bilater- 

 ally-collapsing, blood-red, 120-150 mic. in diameter; perithecial 

 wall composed of coarse cells, variable in form and size, 5-8 mic. 

 in diameter ; asei clavate, 60 X 7-8 mic, 8-spored ; spores mostly 

 2-seriate, fusoid or subclavate, i-septate, hyaline, 10-11 X 3-4 

 mic. {pi 5. /. 26). 



On herbaceous stems of various kinds, Brassica, Solamim. 

 Ipomoea, etc. 



Type locality: New Jersey. 



Distribution : New Jersey to Louisiana. 



Exsiccati: Ellis, N. Am. Fungi 572, 572b; Ellis & Ever- 

 hart's Fungi Columb. 1747. Other specimens examined: New 

 Jersey, Ellis (cotype) ; Louisiana, Langlois 1208, 1775, 1804. 



Closely related to Nectria sanguined (Bolton) Fries, but dis- 

 tinguished by a difference in the form and size of the perithecia 

 as well as by a slight difference in the size and arrangement of 

 the spores. The perithecia resemble in form, Nectria Papiliona- 

 cearum Seaver, but the spores are very different.
