HISTORICAL 199 



water controls were injected into young buds of carnation. From 

 23 per cent (sterile water controls) to 87 per cent (*S. Poae) of the 

 buds failed to open normally. S. Schenckii was recovered from 3 of 

 18 buds inoculated with the fungus, together with 3 other contaminat- 

 ing fungi. The experiment demonstrated the ability of the fungus 

 to grow on dead or damaged plant tissue. 



The disease also occurs spontaneously in certain of the lower ani- 

 mals, notably horses and rats. A number of human cases have been 

 contracted either directly (by bites) or indirectly from such lower 

 animals. There have been two accidental laboratory infections, one 

 from an equine strain, the other from a culture of human origin. 

 In at least one case there has been direct transmission from man 

 to man.

CHROMOBLASTOMYCOSIS 



(Dermatitis Verrucosa, Chromomycosis) 



Historical. The first reports of chromoblastomycosis were made 

 in 1915 by Lane ^ and Medlar ^° * in Boston. They adopted for the 

 fungus they isolated a name given it by Thaxter, Phialophora ver- 

 rucosa Medlar. In 1920 Pedroso and Gomes,^^ in Brazil, reported
