186 GENERAL SYSTEMATIC BACTERIOLOGY 



Later Van Tieghem (1884, p. 1114) evidently regarded this as a 

 form genus. It was also recognized by Billet (1880, p. 24). 



Apparently the genus was validly described, with type species 

 Ascobacteria ulvina Van Tieghem. However, the species is so poorly 

 characterized that its identification is questionable. 



Ascobacterium. A generic name used by Babes (1890, p. 155) in 

 his description of Ascohacterium luteum. This organism is mentioned 

 as common in the air of the laboratory at Buda Pesth and in the water 

 of the Dumbivotza. It forms very pronounced transparent, yellowish 

 colonies on gelatin. The cells are rod-shaped, united in greater or 

 less numbers by a large gelatinous or mucous capsule. 



Mace (1897, p. 962) believes that there may be a relationship ex- 

 isting between this form and that described under the name Asco- 

 coccus. 



Mace (1913, p. 586) states 



Les elements en bdtonnets, ventables Bacilles, sont reunis, en nombre plus 

 ou moins considerdble, dans une grande capsule ovalaire, gelatineuse ou mu- 

 quese. Le nom d'Ascobacillus doit etre consider^ comme synonyme et serait 

 certainement a preferer, si Ton etait tout a fait fix e sur I'individualite de ces 

 types microbiens; on peut conserver le terme Ascobacterium comme provisoire. 

 II y a peut-etre des rapports a etablir entre ce type et ceux d^crits sous le nom 

 d'Ascococcus. 



He describes Ascohacterium luteum Babes and Ascobacterium aqua- 

 tile (Moreno) Mace (Ascobacillus aguatilis Moreno). 



It would seem that this genus has been validly described, with 

 type species Ascobacterium luteum Babes. It is possible that it should 

 be regarded as a synonym of Ascobacillus, q.v. 



Ascococceae. A name of a tribe of cocci of the subfamily Cocco- 

 genae Trevisan proposed by Trevisan (1889, p. 1037). It contains the 

 sub-tribe Euascococceae Trev. with the genera Lamprocystis Schroeter, 

 Ascococcus Cohn, Bollingera Trevisan, Cenomesia Trevisan, Thiocystis 

 Winogradsky, Thiothece Winogradsky, Leucocystis Schroeter, the sub- 

 tribe Gaffkyeae Trevisan with the genera Chlamydatomus Trevisan and 

 Gaffkya Trevisan and the subtribe Amoebohacterieae Trevisan, with 

 the single genus Amoebobacter Winogradsky. 



It is characterized as follows: "Cocci in familias tegumentis vesic- 

 aeformibus gelatinosis (cystidibus) obductae consociati." 



The name has apparently been used by no other author. 



Ascococcos. A form genus proposed by Billroth (1874, p. 13). 

 It was intended to include those growth forms of the poljmiorphic
