508 MEDICAL MYCOLOGY 



einate vesiculosquamous lesions of the hand, producing favic scutula on mouse 

 similar to A. muris. Not inoculable to calf, squamous lesion on rabbit. 



Aleurospores spherical or ovoid, thick-walled ; chlamydospores present. 

 Closterospores 5-7-celled. 



On veal broth, producing superficial white islands with lower surface 

 bright red after tenth day. On potato, an irregular, furrowed, white colony 

 slightly velvety margin, powder}^ and yellowish at the center, medium black- 

 ening. Gelatin liquefied, colony similar to those on liquid media but reverse 

 white ; on Noggerath 's gelatin, colony greenish yellow, reverse black ; on cab- 

 bage stalks colony red under white velvet. 



Without giving cultural details, Massia & Grigorakis report that it colors 

 certain media bright red and that its aleurospores are 3-4 x 2-2.5/^. 



This species has been inadequately described so that its systematic posi- 

 tion is uncertain. Bodin and Sabouraud concluded that it belonged in the 

 genus Trichophyton near T. gypseum (here treated as Ectotrichophyton menta- 

 grophytes) . The lesion and some of the cultural characters suggest Epidermo- 

 phyfon purpureum, while lesions on experimental animals suggest Achorion 

 muris. 



Aleurisma Guilliermondi Grigorakis, C. R. Soc. Biol. 87: 492, 493, 1927. 



Isolated from sycosis from two brothers in Lyon. 



Aleurospores 2-3. 5;u,, occasionally chlamydospores present. Germination 

 with 3-5 germ tubes. Veiy rarely arthrospores. Pigment in granules about 

 the vacuoles, not soluble in ether or chloroform. 



Colonies sulphur colored (pigment more abundant in colonies developing 

 in the dark). Yellow on malt gelatin, liquefied. 



Too briefly described to place definitely, temporarily placed here on the 

 basis of the lesions produced. 



Trichophyton chosenicum Takahashi, Jap. Jour. Derm. Urol. 25: 285, 286, 

 1925. 



Grubyella chosenica Takahashi, Jap. Jour. Derm. Urol. 25: 284, 1925. 



Originally isolated from tinea interdigitalis between toes of a soldier, 

 Korea. Inoculable into man and experimental animals, in the latter produc- 

 ing the ectothrix type of lesion. 



Hyphae 2/x in diameter, intercalary and terminal chlamydospores in old 

 cultures with yellow pigment granules; aleurospores rare, spherical, 1-2/* in 

 diameter. 



Colony white, powdery, hemispheric, yellowing in 10 days, becoming 

 crateriform; yellow pigment turning deep red on treatment with alkali. 



The English resume is too brief for definite placing of this species. Its 

 author evidently thought it belonged in Favotrichophyton or Achorion. The 

 human lesion suggests Epidermophyton, while the lesion in experimental ani- 

 mals suggests Ectotrichophyton or Microsporum. (Cf. M. ferrugineum.)
