fruit are probably only strains of the northern form on apple. At 

 least they will be considered so at present. 



While the form from bean has not been studied so much as the 

 others as to its cuUural characters, it seems to be distinct. Neither 

 this, nor the form on melons, will grow on acid fruit like the apple. 

 T.t would have been interesting if Shear had given the cultural char- 

 acters of the form from bean from which he obtained the perfect 

 stage. It should have been compared with the characters of the 

 form from apples in the south. It is possible that the form from 

 apple might develop occasionally on the bean. Even if he did have 

 the true bean anthracnose and it developed a perithecium identical 

 with the apple bitter rot, the habit of growth of the bean anthracnose 

 is sufficiently different to continue caUing it a distinct species. 



From the evidence available at present, it does not seem advisable 

 to call all these forms the same species. They may finally be placed 

 in one, or at least in a limited number of species, but until the evidence 

 is more certain, it seems best to consider some of them at least distinct. 

 If we use the name first applied to the perfect stage, and we must do 

 this to be consistent with the use of the name Gnomonia veneta used 

 earlier in this paper, the names of the perfect stages found by the 

 writer and brought to maturity would be as follows : 



Glomerella cincta (Stoneman) Sp. & v. Schr., including forms 



purpurea, Dracaena, rubber 



thurium. 



Glomerella frlxtigena (Clinton) Sacc. on apple and quince. 



Glomerella fusarioides, n. sp.^ from Asdepias syriaca. 



Sheldon (38) has recently described the form from Dracaena as 

 a new species, calling it Pkysalospora dracaenae, but from my cultural 

 work it cannot be considered distinct from the form on orchid, the

perfect stage of which has alreadv been described by Miss Stonem.\n 

 (43) .
