TRICHOPHYTONEAE

Trichophyton luxurians Brault & Viguier, C. R. Soc. Biol. 77: 342, 343, 

 1914; Bull. Soc. Franc. Derm. Syphiligr. 25: 401, 402, 1914; Brault, Ann. Derm. 

 Syphiligr. V, 6: 91-94, 1916. 



Ectotrichophyton (Favotrichophyton) luxurians Castellani & Chalmers, 

 Man. Trop. Med. ed. 3, 1004, 1919. 



GruhyeUa luxurians Brumpt. Precis Parasitol. ed. 4, 1305, 1927. 



Producing kerion on children in Algeria. Inoculable to guinea pig, pro- 

 ducing scales surrounding the hair, erythematosquamose lesions with infiltra- 

 tion and bloody crusts. Probably the organism of Artom (1933) belongs 

 here. 



In hair, mycelium irregularly septate, eitlier straight or flexuous ; arthro- 

 spores abundant outside the hair, 5-7/a. 



Only slightly moniliform mycelium formed in hanging drops. Artom 

 (1933) reports ehlamydospores but no closterospores or aleurospores. 



Colony faviform, becoming waxy, slightly humid, more yellowish, ver- 

 miculate with little cupules, drying yellowish gray, surface slightly powdery; 

 center verrucose, much elevated ; margin with a short velvet. 



Favotrichophyton ceroton (Cazalbou) Dodge, n. comb. 



Trichophyton ceroton Cazalbou, Rev. Gen. Med. Vet. 24: 2, 3, 1914. 



Trichophyton faviforme album Gregorio, Actas Dermo-Sifiliograf. [1-7] 

 1934. 



Produces lesions with grayish crusts the size of a 2-franc piece on bulls, 

 C6tes-du-Nord, France. Apparently the outbreak in Asturias reported by 

 Gregorio (1934) should be referred here, or perhaps to F. luxurians. 



Arthrospores about roots of hair, 5/x, spherical, hyphae 3/x, straight, dichot- 

 omous and usually numerous on and within the cuticle of the hair. 



Colonies on maltose agar elevated, yellowish, folded and contorted, glabrous, 

 color of virgin wax, whence its name. 



Favotrichophyton cinereum (Cazalbou) Dodge, n. comb. 



Trichophyton cinereum Cazalbou, Rev. Gen. Med. Vet. 24: 5, 6, 1914. 



?Achorion sp. Truffi, Arch, de Parasitol. 11: 419-424, 1907. 



Isolated from Durham cow at Rennes, France, irregular lesion with slight 

 confluent crusts of cacao color. Later found on 6 bulls, oxen, or calves com- 

 ing from Mayenne and Loire-Inferieure, not reported since. Perhaps human 

 lesions reported by Trufifi (1911) were produced by this species. It is probable 

 that the Trichophyton faviforme du veau described by Bodin, C. R. Soc. Biol. 

 48: 711-713, 1896, and later named T. verrucosum var. Vituli Neveu-Lemaire, 

 Precis Parasitol. Anim. Domest. 76, 1912, belongs here, although it has been too 

 briefly described to be placed with certainty. 



Hairs mildly parasitized with slightly sinuous mycelium and polyhedral 

 spores, 4/A in diameter about the roots. 



Colonies bright orange yellow, forming small tuberculiform masses, after 

 45 days becoming grajdsh blue, ashy, 12-15 mm. in diameter, cerebriform with 

 a floccose white velvet about the margin.
