Isolated from cases of tinea capitis endothrix in Holland, not inoculable 

 to guinea pigs. 



Only chlamydospores and aleurospores present, no closterospores. 



Moist, shining, light brown surface, center with fine spines. After a few 

 weeks, a narrow violet border on Sabouraud agar, lacking on media without 

 sugar. On milk, pale violet. No pleomorphism. 



Var, coccinatum Dodge, n. var.

Producing tinea tonsurans, Sahonraudia type with occasional hair silvery 

 gray, 1-2 mm. long ; also from herpes circinatus and onychomycosis common 

 in Kyushu, not yet found in Japan. On glabrous skin, dark reddish sero- 

 papules, covered with pityriasiform scales, slight pruritus. Inoculation of 

 child showed endothrix lesion; in guinea pigs, rabbits and dogs, positive 

 ectothrix. 



Spores in hair l/x, in scales mycelium 3-4/a, arthrospores 5-6/^. In culture, 

 mycelium 3/a, septate with racquet mycelium; aleurospores on compound 

 thyrses. Chlamydospores pedicellate or intercalarj^, large, often irregular. 



Colony on Sabouraud glucose, at first moist cream color, growth rapid, 

 center dark, brownish purple with cream color border, 8 mm. on fourth day, 

 powdery velvet in center on eighth day. In fourth week, colony 5-6 cm. 

 Pleomorphism beginning in central disc as small protuberance with pink 

 velvet, surrounded with dark brownish purple, with powdery disseminated 

 velvet and 4-8 radial folds ; margin cream color. On Pollacci agar, dark gray
