FUNGI IMPERFECTI 



And one may add : — 



10. S.hronchialeM.onid.gne,j.d>^/[. 



There is, however, some difference of opinion with regard to 

 some of these species; thus de Beurmann and Gougerot consider 

 that the fourth and fifth are only varieties of the second . 



4. 5. beurmanni Matruchot and Ramond, 1905, var. indicum 

 Castellani, 1908. 



5. 5. beurmanni Matruchot and Ramond, 1905, var. asteroides 

 Splendore, 1908. 



Considering them all provisionally as separate species, they may be 

 recognized as follows : — 



A. Conidia large (4-1 1 microns in greatest diameter), with well-developed 



pedicle and presence of lateral spore clusters : — 

 Mycetomas in Madagascar — Lesnei. 



Conidia large with absence of lateral spore clusters : — 

 Traumatic arthritis in America — Councilmani. 



B. Conidia usually small with very short pedicle, which may be absent : — 



I. With radiating bodies. Conidia very polymorphic, round, oval, or 

 bacilliform. varying from 4-8 microns in greatest diameter — 

 Asteroides. 



II. Without radiating bodies: — 



[a) Conidia not numerous. Ferments lactose, not saccharose — 



Schenki. 



[b) Conidia numerous: — 



1 . Hyphae 2 or more microns in diameter : — 



(a) Cultivated:— 



(i.) Colonies dark from the first — Gougeroti. 

 (ii.) Colonies whitish at first: — 



(1) Colonies finally black. Ferments saccharose, 



not lactose — Beurmanni. 



(2) Colonies lightish brown — Dori. 



(3) Colonies whitish grey to black. Hyphae wide, 



3 to 4 microns — Indicum. 



(b) Not cultivated. Hyphae 5 to 7 microns in diameter — 



Bronchiale. 



2. Hyphae less than 2 microns in diameter. Hyphae 0*5 to i 



micron in diameter — Jeanselmi. 



Pathogenicity. — ^They usually give rise to lesions in the skin and 

 deeper tissues, resembling those of tertiary syphilis (gummata, etc.) 

 or tuberculosis, but 5. lesnei produces a disease like mycetoma. 



Treatment.- — Ks> a rule the diseases are amenable to iodide of 

 potassium . 



Sporotrichum schenki Hektoen and Perkins, 1900. 



Synonyms. — Sporothrix schenki Hektoen and Perkins, 1900 ; 

 Rhinocladium beurmanni Verdun, 1913. 



Discovered by Schenk in a case of gummatous lymphangitis in 

 1896 in North America. Easily grown on glucose, maltose, and 

 other sugar media. Optimum temperature 30° to 38° C. Growth 

 with an irregular surface, generally of white colour, but old cultures
