 presented a summary of their work before the Botanical Society of

 the life histories of forms obtained from 18 different hosts had been 

 worked out. Since then the number has been doubled, and both the 

 conidial and ascogenous stages of Glomerella from 36 different hosts 

 have been studied and the conidial forms from 45 different hosts have
