XIV, 1 Merrill and Wade : The Validity of Discomyces 61 



rejected de Toni and Trevisan's objection that Meyen had given 

 the name to another organism as an unreasonably strict interpre- 

 tation of the principles of botanical nomenclature. On the other 

 hand, for the rest of the group he rejected Streptothrix and 

 accepted Nocardia. This subdivision of the group has been 

 adopted in several American bacteriological textbooks. How- 

 ever, Chester (16) adopted the first classification of Lehmann and 

 Neumann, except that Oospora was replaced by Streptothrix 

 Cohn. Clements (17) included these organisms among the Schizo- 

 mycetes; he followed Migula's earlier classification, except that 

 Nocardia was substituted for Streptothrix Cohn, emend. Mig. 



Foulerton(22) argued that, since the other names that had 

 been proposed had dropped out of use, only Streptothrix and 

 Actinomyces remained to be considered. He chose the former 

 because, although Corda had used it in 1834, it had become uncer- 

 tain to what particular organism the term had been applied; 

 further, a committee of the Pathological Society of London in 

 1899 had recommended the term "streptotricosis" as the ap- 

 propriate clinical designation for the infection. Musgrave and 

 Clegg(46) acknowledged that Nocardia was probably more 

 strictly correct, but "chiefly because of usage, and therefore 

 somewhat arbitrarily, tentatively accepted Streptothrix * * 

 *." They suggested the possible advantage of substituting an 

 entirely new name, Carteria (Carterii, sic!), evidently hoping 

 that by this means further controversy might be eliminated. 



Pinoy has divided the group into Nocardia, which is to include 

 most of the species, and Cohnistreptothrix, said to be designed 

 to replace Cohn's invalid Streptothrix. The article that con- 

 tains his argument is probably one by Pinoy and Morax,(52) 

 which is not available to us. According to Chalmers and Chris- 

 topherson(i5) the characteristics of this genus are preference 

 for anaerobiosis, difficulty of cultivation, and nonproduction of 

 arthrospores ; in it they include Cohn's Streptothrix foersteri 

 and Israel's Actinomyces from man (Streptothrix israeli Kruse, 

 1896). 



Vuillemin,(60) as a result of the adoption by the 1910 meeting 

 of the International Botanical Congress at Brussels of a program 

 for the next congress that included the determination of the 

 point of departure for the nomenclature of the Schizomycetes 

 and the elaboration of lists of nomina conservanda for these 

 organisms, has recently published a revised generic classifica- 

 tion, which was intended to be submitted for consideration at 

 the scheduled London (1915) meeting of the congress. In an 

 appendix to this work he includes the family Microsiphones,
