Doubtful and Excluded Species 



Velutaria cinereofusca (Schw.) Bres. has been regarded as a synonym of 

 this species but is now regarded as a Cyplella. For details see page 275. 



Velutaria griseovitellina Fuckel, S>mb. Myc. 300. 1869. This species 

 has been reported from Washington under the name of Tapesina griseovitellina 

 Hohn. The 3-septate spores would place it in the genus Belonium as treated 

 here. 



Schweinitzia phaeospora (Cooke) Massee, Brit. Fungus-Fl. 4: 135. 1895; 

 Cenangium phaeosporum Cooke, Grevillea 12: 44. 1883; Phaeangium phaeo- 

 sporum Sacc. S3II. Fung. 16: 765. 1902. No material available but appar- 

 ently scarcely distinct from the preceding.
