392 GENERAL SYSTEMATIC BACTERIOLOGY 



gelblichen bis gelbraunlichen Gallertmassen gehauft oder im schleimigen Lager 

 anderer Kellerbacterien verstreut. 



An wenig feuchten Mauern in alten Weinkellern, meist in Gesellschaft des 

 Bacillus subtilis var. cellaris; so auf der Altstadt und in einem Weinkeller auf der 

 Neustadt. 



De Toni and Trevisan (1889, p. 1033) make the species Mycothece 

 cellaris Hansgirg a synonym of Klebsiella cellar-is Trevisan. 



The name has apparently not been used by other authors. It is 

 rejected by Erwin F. Smith (1905). If the organism described is 

 worthy of generic differentiation, it would appear that the genus 

 name is valid. 



Mycothrix. A name applied to chains of spherical organisms by 

 Itzigsohn (1867). Cohn (1872, p. 147) makes the following statement: 

 ^'Itzigsohn und Hallier haben fiir die Rosenkranzketten der Kugel- 

 bacterien den Namen Mycothrix vorgeschlagen; ich bezeichne sie hier 

 als Torulaform." 



Apparently the term has never been used in a strict generic sense. 

 The nearest approach seems to have been the ascription by De Toni 

 and Trevisan (1889, p. 1059) to Friedberger of the term "Mycothrix 

 bei Pleuropneumonie des Pferdes" (1873, p. 91). An examination of 

 the latter reference fails to show any such use. It is invalid. 



Myxobacillus. A generic name used by Gonnermann (1907, p. 

 877) (with the spelling Myxobazillus) for a species of bacterium, M. 

 hetae isolated from sugar beet juice. The organism is a slender rod, 

 0.3 by 2.3-4. 5/i. Easily stained. Often granules. No definite cap- 

 sule. Grows at 35°C., but not killed at 60°. Non-motile. It forms 

 spores in twenty-four hours which are oval, of a diameter greater than 

 that of the mother cell. Before spore formation the organism occurs 

 in chains like anthrax bacillus; the filament falls apart into segments 

 each of which produces a spore. It grows well on ordinary media. 

 In sucrose solutions gas and acid are not formed. The solution 

 becomes opalescent and viscous. Apparently this is a synonym of 

 Bacillus. 



Myxobacter. A generic name proposed by Thaxter (1892, p. 493) 

 for a species of the Myxohacteriaceae, M. aureus. The following generic 

 description was given: "Rods, forming large rounded cysts, one or 

 more free within a gelatinous matrix raised above the substratum." 

 Thaxter later noted that this generic name is invalid because of the 

 prior use of Polyangium q.v. for this form. This name has accordingly 

 been abandoned in later writings on this group.
