MYCETOMA AND PARAMYCETOMA 



C. The Asian Black Maduromycosis. 



There is only one type known at present — viz., Carter's black 

 maduromycosis, caused by Glenospora semoni Chalmers and Archibald, 

 1917, which can be readily differentiated from Glenospora khartou- 

 mensis Chalmers and Archibald, 1916, by the following characters:— 



(r) Grown on clear maltose agar in Khartoum after twelve days in an un- 

 capped tube at 30° C. : — 



G. semoni produces a cupola-shaped, large, central black mass 

 with an outlying fringe of white. 



G. khartoumensis produces a black growth, consisting of a central 

 crumpled ridge or hillock placed on a grooved black plateau, and 

 with hardly any white fringe. 

 (2) and (3) Grown on glucose agar and blood serum; there are marked 

 differences between the two fungi. 



D. The American Black Maduromycoses. 



(1) Wright's black maduromycosis, which was found in the United 

 States in an Italian woman who had left Italy, where black maduro- 

 mycosis occurs, an indefinite number of years before the onset of 

 the malady. The systemic position of the causal fungus is unknown. 



(2) Seheult's black maduromycosis, which was found in the West 

 Indies in a native of India, who had left that country twelve years 

 before the onset of the malady. The nature of the causal organism 

 is unknown. 



II. THE WHITE OR YELLOW MADUROMYCOSES. 



Thesemay be divided into: — 



A. The European white maduromycoses. , 



B. The African white maduromycosis. 



C. The Asian white maduromycosis. 



A. The European White Maduromycoses. 



(1) Brumpt and Reynier's white maduromycosis, caused by Indiella 

 reynieri Brumpt, 1906, with a large soft grain, found in Paris. 



(2) Tarozzi and Radaeli's white maduromycosis, caused by Scedo- 

 sporium apiospermum (Saccardo, 1911), with a small, rather hard, 

 and yellowish grain, found in Sardinia and Italy. 



B. The African White Maduromycosis. 

 Nicolle and Pinoy's white maduromycosis, due to Sterigmatocystis 

 nidulans (Eidam, 1883), with grains of size varying from those 

 which are almost microscopic to others about the size of a pea, of 

 rounded or polyhedral form, and of variable colour, being dirty 

 white or yellowish-white, and soft in consistence, and found in 

 Tunisia.
