GENERAL SYSTEMATIC BACTERIOLOGY 333 



Hyphomycetes. A general name frequently used by mycologists 

 to include the molds. It has been used by Lehmann and Neumann 

 (1896, p. 107) to include the mold-bacterial genera Mycobacterium,. 

 Corynebacterium and Oospora with the following diagnosis: 



Chlorophyllfreie Fadenpilze teils immcr, teils vorwiegend mit echt verzweigtem 

 Mycel ohne Endosporen, z. T. mit Bildung conidienartiger Sporen. Von dieser 

 sehr grossen, durchaus provisorischen Familie haben wir nur 3 Gattungen be- 

 riicksichtigt, ausschliesslich solche, die durch ihr diinnes Mycel in Fragmenten als 

 Spaltpilze imponieren konnten und z. T. allgemein imponiert hatten. 



Later these authors substituted the name Actinomycetes (q. v.). 



Hjrphomicrobium. A generic name proposed by Stutzer and Hartleb 

 (1901, p. 76) for a species H. vulgare. The description is summarized 

 by Enlows (1920, p. 49) as follows: 



A nitrifying (?) organism found in soil. Related to the bacteria and to the 

 hyphomycetes. On nitrate agar, small homogenous rods, with usually pointed 

 ends, 0.6 to O.Sju by 1 to l.o/:* long. Stained with phenol fuchsin a darker central 

 body surrounded by a clear zone may be observed. Egg-shaped forms in older 

 cultures, which send out threads, some of which show true branching. Multipli- 

 cation also by transverse division. Found also in cement which they think was 

 decomposing through the assistance of this organism. 



Hypnococcus. A pseudo-generic name given by Bettencourt, 

 Kopke.de Renzende and Mendes (1904, p. 55) to a "diplo-streptococcus" 

 which they isolated from the meningeal fluid of patients suffering from 

 sleeping sickness and believed this to be the causal organism. The 

 name is not a true generic designation. 



Indiella. A genus of fimgi created by Brumpt (1906 according to 

 Castellani and Chalmers 1919). It is of bacteriological significance 

 because Indiella somaliensis Brumpt was later made a synonjTn of 

 Nocardia somaliensis by Chambers and Christopherson (1916). 



Indiellopsis. The following summary is given by Enlows (1920, 

 p. 49): 



According to Chalmers and Christopherson: Ann. Trop. Med. and Parasitol., 

 Liverpool, 1915, pp. 240-255. Brumpt classified the cause of certain mycetomas 

 of the hand as Indiella somaliensis (1906). In 1913 he renamed this species Dis- 

 comyces somaliensis, and in the same year created a new genus or subgenus for it : 

 Indiellopsis somaliensis (Brumpt, 1906). Brumpt based his Indiellopsis on the 

 fact that the species secreted around itself in the grain a hard sheath, insoluble 

 in potash and eau de javelle, which no other Nocardia is known to do. 



Indolococcus. A generic name tentatively proposed by Orla-Jensen 

 (1909, p. 340) in the following paragraph:
