F UNGA CEm—PH YCOM YCETES 



forming a snow-white mass. Sporangia globular, of black colour 

 when ripe. Spores ovoid, smooth. Columella is at first globular, 

 but later takes a cylindrical shape, and when the spores have 

 become detached, shows a pecuHar mushroom-like appearance. 



This species was discovered by Ciaglinski and Hewelke in a case 

 of black mycosis of the tongue. 



General Remarks on Mycoses due to Species of the Family 

 Mucoraceae. 



These mycoses are generally called mucormycoses. They Jiave 

 been recorded several times in man. 



Mucormycosis of the Nose. — Several cases are on record in 

 which species of Mucoraceae (generally Lichtheimia corymhifera) 

 were found in various affections of the nose. Their pathogenic 

 role in such affections has not been demonstrated with certainty. 



Mucormycosis of the Tongue. — Ciaglinski and Hewelke, and 

 later Seniyiak, have described cases of so-called '-black tongue,' 

 due to Rhizopus niger. 



Mucormycosis of the Ear — Otomucormycosis. — Several cases 

 are found in the literature (Siebenmann, Boke, Hiickel, etc.). 

 Almost a\w2iys Lichtheimia corymhifera was present. In the tropics 

 we have observed two cases in which L. ramosa occurred. When 

 the fungus is in great quantity, the patient complains of tinnitus 

 aurium and deafness — the same symptoms as those produced by 

 a plug of cerumen in the external auditory meatus. 



Mucormycosis of the Lungs.— This condition is rare. 

 Fiirbringer has described two cases in which L. corymhifera was 

 found at the autopsy in some hcemorrhagic foci in the lungs. Lucet, 

 Costantin, and Lambry described a case of bronchitis in a woman 

 due to Rhizomucor parasiticus. The expectoration was rather 

 scanty and mucopurulent, but without blood. Mycelial threads 

 and spore-like bodies were present. Cultures were made, and the
