TRICHOPHYTONEAE 517 



suggesting the fa vie candelabra of Achorion (Fig. 86, 1). Pedicellate chlamy- 

 dospores abundant, 10-15/a in diameter, occasionally up to 20/x, sometimes 

 detached from the mycelium (Fig. 86, 5, 6). 



Colony at first whitish, elevated, hemispheric with a very thin velvet, 

 growth veiy slow. On glucose agar reaching a diam.eter of 5 mm. in 40 days, 

 acuminate, the central portion remaining hemispheric, the margin with radial 

 folds. Colonies very hard and adherent. On conservation medium, gi^owth 

 more rapid, in general suggesting colonies of Favotrichophyton album. 



Favotrichophyton Langeroni (Baudet) Dodge, n. comb. 



Gruhyella Langero7ii Baudet, Ann. Parasitol. Hum. Comp. 8: 411-418, 1930. 



Producing' crusts in circular lesions on dromedary. Inoculable in guinea 

 pig, lesions giving fleeting resemblance to favus. 



Mycelium 4-4.5/x in diameter ; arthrospores abundant, 6-10/^,, sometimes in 

 chains terminated by mycelial branches; aleurospores budding from irregu- 

 larly inflated cells ; chlamydospores intercalary or terminal, not pedicellate ; 

 accessoiy organs various, sometimes suggesting favic candelabra or clostero- 

 spores. 



Colonies white, conic, sometimes furrowed as is a snail shell, with a short 

 white velvet.

Case history by Gonzales Uruena, Revista Mex. Biol. 4: 90-93, 1924. 



Very severe case of tinea tonsurans affecting a large portion of the hair, 

 Mexico. 



Arthrospores 5-8/a, in the hair, aleurospores lateral, chlamydospores pres- 

 ent, closterospores pluriseptate, 2-7-celled. 



Central portion of colony cerebriform or folded, dry, white, margin broad 

 and flat, no radial furrows.

Causing tinea capitis of native in Eritrea. 



Colonies white, floccose, spreading. Hyphae emerging from substrate, 

 then more or less adhering, branched, septate, 3-7/x in diameter. Arthrospores 

 4-9/i in diameter, rounded, oblong or irregular, solitary or in irregular chains, 

 intercalary or acrogenous, suggesting conidia. Chlamydospores intercalary, 

 irregular 14-20 x 40/x,. 



Differs from F. violaceum and F. glahrum by abundant and in-egular for- 

 mation of chlamydospores and from F. halcanicum by the branching of the 

 mycelium.

Isolated from lesions on bull, St. Brieuc, France, material sent by Serise, 

 not reported since the original case.
