526 MEDICAL MYCOLOGY 



Trichophyton verrucosum var. asini Neveu-Lemaire, Precis Paras. Anim. 

 Domest. 75, 1912. 



Ectotrichophyton (Favotrichophyton) verrucosum Castellani & Chalmers, 

 Man. Trop. Med. ed. 3, 1003, 1004, 1919. 



Isolated from glabrous, irre^ilar, dry areas covered with a thick layer of 

 grayish scales without underlying- suppuration, folliculitis or broken hairs, on 

 neck and ears of donkey. Transmitted to three out of four persons who cared 

 for the animal. Human lesions red, scarcely scaly circles with small vesico- 

 pustules filled with a creamy white pus. Produced an ectothrix lesion on 

 guinea pig. 



Colony round, immersed disc 2 cm. in diameter, central elevated knob 

 gray with a grayish white margin, humid with radial furrows. On malt agar, 

 colony acuminate, gray, size of a pea surrounded by immersed rays, branched 

 as a fern leaf, surface rough, growth slow. On potato, growth slow, gray, 

 humid, little elevated, verrucose, finely tomentose in places. 



Favotrichophyton fuligineum (Ogata) Dodge, n. comb. 



T rich uphyi 0)1 fuligineum Ogata, Jap. Jour. Derm. Urol. 29: 1183-1232, PI. 

 41, 25 figs., 1929. 



Bodinia fuliginea Ogata, Jap. Jour. Derm. Urol. 29: 1183-1232, PL 41, 

 25 figs., 1929. 



Isolated from tinea tonsurans, Sahouraudia type at center of lesion, no 

 hair at margins, hair silver white, breaking 2-3 cm. from scalp. Spores in hair 

 4-5/i. Inoculable into guinea pig, rabbit, cat, and dog. Inoculation in man 

 produced 1 kerion, 2 maculovesiculose lesions and 1 superficial lesion. Organ- 

 ism reisolated from all cases. 



Hyphae 3-4/a. Chlamydospores intercalary and terminal as in F. violaceum, 

 colored grayish yellow. Few aleurospores noted. 



Growth slow, 1 cm. in 3 weeks, surface shining and smooth, center folded 

 and knotted, greenish black, margin grayish white. Medium colored blackish 

 green. Similar on 4% honey agar and on 40% koji agar. On glucose agar, 

 colors brighter, suggesting a film of petroleum on water. On Pollacci agar, 

 colony greener. 



Favotrichophyton epilans (Megnin) Dodge, n. comb. 



Trichophyton depilans Megnin, Arch. Gen. Med. 141: 294-304, 1878 [nom. 

 nud.]. 



Trichophyton epilans Megnin, Bull. Soc. Centr. Med. Vet. 44: 183-186, 1890. 



Lesions on calves in Normandy, very contagious to man, producing sy- 

 cois, and to horse. Crusts yellowish, not clay color. Hairs not break- 

 ing above the skin but falling completely, with pus [ ?] formation in the fol- 

 licle. Spores in lesions 5-6/a in diameter, yellowish. Lesions on horse similar, 

 but smaller. 



Colonies slightly yellowish on gelatin, rapidly liquefying the substrate. 



This species has been too briefly described for certain identification, but 

 the formation of yellow crusts seems distinctive.
