The author describes the forms found in material obtained from a human lesion localized in the mouth. The patient was a farmer and the diagnosis unknown. The author found yeast forms, some germinating, resembling those found in the mycosis of LUTZ. It was Sporotricosis and only once, in 96 cases, has the author found these fungous forms in the suspected material. The cultures in Sabouraud glucose and in many other media were positive for Sporotrichum, resembling that described by BENEDEK in 1926 (variety?) principally by the reddish colour of some cultures. The author thinks there is, perhaps, a mutation influenced by the surroundings and the light in certain cultures and that the dark pigment is the dominant one. He considers that the pigment will not do for the differentiation of species and that it is, really, Sporotrichum Schencki-Beurmanni. The author calls attention to the question of diagnosis and studies separately, each of the elements in which his opinion is based, finding that only a macro and microscopic study of the cultures decides the question.
