76 The North American Cup-Fungi 



New York City, over a period of years, and in no case has the 

 fungus been associated with the rhizomes of this or any other 

 host. While there might be a mycehal connection, none was 

 apparent. This leads us to suspect that our American form may 

 be distinct from the European. However, the two agree so well 

 in other characters that for the time being our species are re- 

 garded as identical with the European. 



2. Sclerotinia temulenta (Prill. & Delacr.) Seaver, comb. nov. 



Phialea temulenta Prill. & Delacr. Bull. Soc. Myc. Fr. 8: 23. 1892. 



? Endoconidium temulentum Prill. & Delacr. Bull. Soc. Myc. Fr. 7: 116. 1891. 



Conidial stage consisting of globose, or subglobose conidia 

 produced in chains within the branches and near the tips of the 

 conidiophores. 



Apothecia solitary, or gregarious on a sclerotium formed in 

 the seed of the host, stipitate, at first partly closed, pallid, from 

 ochraceous to honey-colored, .5-7 m in diameter; hymenium 

 plane to slightly convex; stem slender, 7-10 mm. long and .5-1 

 mm. thick; asci cylindric, reaching a length of 130 ju and a 

 diameter of 5 m, 8-spored; spores, 1-seriate, fusoid, 4-5 X 10^; 

 paraphyses filiform, slightly enlarged above 1.5-2 ji thick. 



On fruits of Secale cereale to which it gives poisonous proper- 

 ties. Said to be a very destructive parasite. 



Type locality: Europe. 



Distribution: Williamette Valley, Oregon; also in Europe. 



Illustrations: Bull. Soc. Myc. Fr. 7: 116,/. 1 (conidia). 



If Prillieus and Delacroix are correct in assuming that this is 

 the perfect stage of Endoconidium temulentum and we follow the 

 Whetzel scheme of separating genera on the basis of their 

 conidial stages this should be made a separate genus since it is 

 the only member of the tribe which has an Endoconidium as the 

 conidial stage. 



3. Sclerotinia juncigena (Ellis & Ev.) Whetzel, Farlowia 2: 

 432. 1946. 



Ciboria juncigena Ellis «& Ev. Proc. Acad. Sci. Phila. 1894: 348. 1894. 



Sclerotia one, possibly more within a diseased culm, slender, 

 cylindric, with truncate, slightly rounded ends, reaching a length 

 of 15 mm. and a diameter of 2 mm., externally black, sulcate, 

 internally white when mature, enclosed in a cavity in the pith 

 region of the culm.
