Aleuriosporia instead of Triclio'phyton as defined by Ota & Langeron. Also 

 Sahouraiidites, as Ota & Langeron characterized it, Closteriosporia in the sense 

 of Epidermophyton (not as Grigorakis described it), Gruhyella and Bodinia as 

 Ota & Langeron characterized them, and finally Arthrosporia (in the sense of 

 Endodermophyton Cast., not as Grigorakis used it). He also makes the error 

 of typifying both Spiralia and Sabouraudites by T. mentagrophytes under the 

 names Spiralia asteroides and Sabouraudites asteroides. His spelling is fre- 

 quently incorrect. Bruhns & Alexander (1928) follow Sabouraud without 

 change. 



The latest attempt at revision is that of Langeron & Milochevitch (1930) 

 who revived the use of complex carbohydrate media, such as starch, and found 

 that several characteristic organs (e.g., spirals and nodular organs) were pro- 

 duced on these media in species which failed to produce them on Sabouraud 's 

 agar. They therefore take a very reactionary view and recognize Epidermo- 

 phyton, and Sabouraudites of their former classification, and put all the rest in 

 Trichophyton. They would abolish the subgenera they formerly erected in 

 Sabouraudites and the distinctions of Bodinia, Grubyella (Achorion), and En- 

 dodermophyton. They admit, however, that many organisms may not fit their 

 present scheme. 



From the above facts it is evident that many authors since Sabouraud have 

 not followed the international rules of nomenclature in creating new names in 

 their proposals. Some have not even typified their genera, so that the appli- 

 cation of their names remains doubtful. After a careful consideration of the 

 morphology of the fungus in both the lesion and the culture media, it would 

 seem that in the present state of our knowledge the following groups are 

 entitled to generic rank :
