Doubtful and Excluded Species 



Helotium alhovirens Cooke, Bull. BuflFalo Soc. Nat. Sci. 2: 299. 1875. 

 Apothecia scattered, or subgregarious, pale greenish-white, sessile, attached 

 beneath bv white, arachnoid threads, 1 mm. in diameter; hymenium plane, or 

 convex, darker when dry; asci cylindric, 8-spored; spores long-ellipsoid, 

 straight, or curved, 3 X 18 m; paraphyses not observed. On wood of Acer, 

 New Jersey. 



Helotium alniellum (Nyl.) Karst. Not. Soc. Fauna Fl. Fenn. 11: 239. 

 1871; Peziza alniella Nyl. Not. Soc. Fauna Fl. Fenn. 10: 45. 1869; Phialea 

 alniella Sacc. Syll. Fung. 8: 257. 1889. This species has been reported from 

 Washington by Dr. B. Kanouse on maple seed. It has previously been re- 

 ported on catkins of Alnus and would seem to belong to the genus Ciboria as 

 defined by Whetzel.
