TBICHOPHYTONEAE 545 



Closterospores 60 x 20yu,, up to 10-celled; aleurospo]-es and racquet myce- 

 lium present. 



Colony witli central jjunctiform umbo, surrounded by a small white zone 

 of short, compact velvet divided by radial furrows into 3-4 sectors ; margin 

 broad, fine silky velvet. At one month, 6 cm. in diameter with the furrows 

 nearly obliterated, pleomorphism already evident. On Sabouraud's conserva- 

 tion a^ar, colony similar to that of M. villosum.

Closterosporae rarae vel nullae, degeneratae ; chlamydosporae abundantes, 

 evolutae ; aleurosporae rarae, atypicae ; ex tinea capitis microsporica tricho- 

 phytica cum inflammatione in nationibus flavis. 



Closterospores rare or absent, not well differentiated ; chlamydospores 

 abundant and apparently retaining traces of sexuality ; aleurospores rare and 

 not very typical ; in the present state of our knowledge confined to man and 

 to the yellow race ; lesions predominantly tinea capitis microsporica, but more 

 inflammatory types present on the glabrous skin, intermediate in this respect 

 between Neomicrosporum and Eumicrosporum.

Producing tinea tonsurans microsporica of children in Japan; also re- 

 ported from lesions of the glabrous skin and from eczema marginatum. Not 

 inoculable into guinea pigs. Reported as very common in Japan and Man- 

 churia. 



In the hair, mycelium 2.5-3/x in diameter, straight and vertical Avitli little 

 interweaving; septa not seen, arthrospores 2.3-3/a, not in chains, walls thick 

 In scales, hyphae undulate, sometimes in sigmoid curves, frequently branch- 

 ing dichotomously with lateral protuberances ; septa rare. In cultures, chla- 

 mydospores large, 30/t in diameter, intercalary or terminal (Fig. 87) ; pectinate 

 hyphae present but not abundant, aleurospores and closterospores not observed. 



Colony deep reddish yellow, sometimes paler. On malt infusion, more 

 humid, after 7-8 daj^s, powdery sulphur colored, becoming either flat with 

 distinct lanceolate rays and Avitli folded center, or vermiculate and folded 

 as in Achorion Schoenleini, 4c-5 cm. in diameter. On potato, irregularly acumi- 

 nate, straw color or ochraceous. On Griitz agar, bright chocolate brown. On 

 Pollacci agar, more folded and yellower than on other media, center white, 

 powdery, surface dry. On peptone agar, similar to colonies on Sabouraud
