254 GENERAL SYSTEMATIC BACTERIOLOGY 



einer Anzahl kleiner gestreckt elliptischer, bakterienartiger Korper, welche eine 

 starker grim gefarbte Rindenschicht und eine hellere centrale Partie erkennen 

 lassen. Indem diese Korper, in etwas unregelmassigen lockeren Langsreihen 

 angeordnet, mantelformig einen axialen farblosen (wohl gallertigen?) Hohl- 

 raum umschliessen, kommt das oben geschilderte Aussehen bei schwacher Ver- 

 grosserung zustande. Freibeweglich mit Hilfe von Geisseln. Lange des Organis- 

 mus : 0,009-0,012 mm. Breite 0,005-0,007 mm. 



Vermehrung durch Querteilung: der Organismus streckt sich in die Liinge 

 und schniirt sich in der Mitte durch eine Ringfurche quer durch. Auch mehr- 

 fach Zerfall in die einzelnen bakterienartigen grimen Korper beobachtet, welche 

 sich selbst wieder quer teilen konnen. Auf diese Weise kommen unregelmassige, 

 bisweilen netzartig durchbrochene und dann im Habitus an Lamprocystis rosea- 

 pcrsicina erinnernde hellgriine Kolonien zustande. 



Later (1913, p. 99) he included this genus in his family Chlorohak- 

 teriaceae. Its position among the bacteria is questionable. 



Chloronium. A generic name proposed by Buder (1914, p. 80) 

 with the species Chloronium mirahile. The type species was desig- 

 nated by Enlows as follows: 



Type species (monotypy ) . C. mirahile. Found in water in the Leipzig Botanic 

 Garden. A cylindrical rod 0.7 to Ip by 1 to 2n with rounded ends, sometimes 

 slightly curved, green, united into a zoogloeal mass, in the center of which is a 

 colorless, spindle-shaped, 1-polar flagellate organism. The latter measures 2 to 

 2.5 by 5^. Multiplication by transverse division. The "peripheral component" 

 is sometimes of coccus form also green of 0.75m diameter. Usually about 10 to 30 

 arranged in rather definite order about the colorless central organism. Perfiliev 

 (j. Mic. Biol., V. 1, 1914, p. 223) says that the peripheral forms described here are 

 identical with Chlorochromatium aggregatum Lauterborn. Buder is in doubt as to 

 the systematic position of Chloronium. Perfiliev describes the "central organ- 

 ism" of Buder's Chloronium as Cylindrogloea, q.v. 



Chondromyces. A genus credited to Berkeley and Curtiss by 

 Berkeley (1857, p. 313) in an illustration, figure 70, which has the explana- 

 tion "Chondromyces crocatus Berkeley and Curtiss, with its spores. 

 Both magnified. From specimens on a decayed gourd from South 

 Carohna." In the text the genus is not described, but is classified 

 under the Hyphomycetes, in the family Isariacei Corda-Stern. Under 

 Isarei Fr. (p. 314) is the following statement: 



Several genera which find their proper place in this highest group, and the last 

 are, in fact, compound forms of organisms which appeared under other tribes — • 

 Chondromyces and Stigmatella are compound Mucedines. 



The first description was published by Berkeley (1874, p. 64) as 

 follows: "Stipes e floccis compactus ramosus induratus: sporae 

 apicales."
