SUMMARY 



The subject of this paper consists of two interesting cases or Madura- 

 foot, observed in Bahia, documented by clinical examination (and one 

 of them by radiography), by anatomo-pathological study and by micro- 

 scopical research of the fungi that have produced the lesions. 



The first case is a podal mycetoma of yellowish-white granules. The 

 author found and succeeded in isolating a Discomyces that develops itself 

 very slowly in the cultural media, assuming a mulberry-like look on 

 pctato. It does not grow at all on Sabouraud's medium. 



By these characters the author considers this fungus to be different 

 from the Discomyces madurae Vincent and he describes it as new species, 

 that he names Discomyces bahiensis. 



The second case is a podal mycetoma of black granules, from which 

 the author succeeded in isolating, in pure culture, another fungus that 

 develops easily on several media, above all on Sabouraud's glucose-agar, 

 on potato and in straw infusion. Such fungus secretes sclerotia and a 

 great quantity of pigment that alters the colouring of the culture me- 

 dium, rapidly darkening it. 



It is a new species of Madurella, that the author calls Madurella 

 Ramiroi. 



The experimental inoculation of the Discomyces bahiensis as well as 

 that of the Madurella Ramiroi were attempted in pigeons, rats and bats, 

 but fruitlessly. 



Information regarding the works on Maduromycosis, made in Brazil, 

 is given in the text.
