Doubtful Species 

 Byssonectria rosella Cooke & Hark.; Cooke, Grevillea 12: loi. 

 1884. Described from imperfect material. 



Byssonectria fimeti (Cooke) Sacc. Syll Fung. 2: 457. 1883. 

 The species was described from material collected by Ravenel. 

 This material has been examined by the writer and the only

Hypomyces exiguus Pat. Bull. Soc. Myc. France 18: 180. 1902.

 small, 130-160 mic. in diameter, white or slightly yellowish; asci 

 numerous, without paraphyses, cylindrical, 30-35 X 3-4 mic, 

 8-spored; spores i-seriate, hyaline, ovoid, smooth, simple, small,
