518 MEDICAL MYCOLOGY 



In the lesions, artlirospores 5-6/i in diameter. 



Colonies greenish yellow, citron color, flat, somewhat convoluted, but the 

 convolutions sunk in agar, suggesting the petals of a flower, with a wide 

 velvety margin. 



Favotrichophyton floriforme (Beintema) Dodge, n. comb. 



Tricliophyton floriforme Beintema, Arch. Derm. Syphilis 169: 577-581, 6 

 figs., 1934. 



Isolated from tinea tonsurans, Sabouraudia type with pustules, in Gronin- 

 gen, Netherlands. Slight scaling on guinea pig after 10 days, but no invasion 

 of the hair and spontaneous healing in 3 weeks. 



Hyphae 3-5/x in diameter often ending in clavate swellings about 8/* in 

 diameter. Aleurospores in clusters; chlamydospores terminal, lateral, or in- 

 tercalary 12-18/i. Only chlamydospores in peptone solution. 



Colonies with a broad zone below the surface of the medium, smooth with 

 radial furrows, margin not especially radiate, cream color with a slight um- 

 bilicate center, and a finely crackled surface. On Griitz agar, growth more 

 rapid, yellowish green with central umbilicate and folded area and a flatter 

 margin, the center finally becoming cream color and the yellow green moving 

 toward the margin. The radial furrows are very regular and suggest the 

 petals of a flower, whence its name. Center finally crackled. 



Except the host there seems little to differentiate this species from the 

 preceding, but I have preferred not to reduce it to synonymy in the absence 

 of a suggestion that it might have been contracted from a member of the 

 Bovidae. 



Favotrichophyton flavivirens (Americo da Veiga) Dodge, n. comb. 



Trichophyton flavivirens Americo da Veiga, Brasil Med. 43: 836. 837. 1929. 



Producing alopecia and kerions on Portuguese in Brazil. 



Arthrospores 4-6/^, in cuticle of hair and follicle. 



Colonies humid, of two concentric discs, the higher and inner one yellow 

 cream, the lower and outer white. Subcultures similar but central plateau 

 green, outer yellow cream. 



Favotrichophyton balcaneum (Castellani) Dodge, n. comb. 



Trichophyton balcaneum Castellani, Jour. Trop. Med. Hyg. 22: 173, 174, 

 2 figs., 1919. 



Bodinia balcanea Ota & Langeron Ann. Parasitol. Hum. Comp. 1: 329, 

 1923. 



Producing pseudopityriasis capitis in Macedonia. 



Mycelium hyaline, 3-4/a, intricately branched, with chlamydospores and 

 nodular organs. 



Colony yellowish white, glabrous, elevated above the substrate, a central 

 boss with many short radial furrows. On glucose agar, growth very slow. 

 On gelatin liquefaction rapid. 



Favotrichophyton luxurlans (Brault & Viguier) Neveu-Lemaire, Precis 

 Parasitol. Hum. 55, 1921.
