MEDICAL MYCOLOGY 



Muskatblit (1933) in comparing this species with E. rubrum describes 

 his cultures as follows: Mycelium straight, more regular, chlamydospores 

 much less numerous, closterospores few and poorly developed; aleurospores 

 abundant, borne on either simple or compound thyrses ; arthrospores occa- 

 sional. His cultural characters agree well with Bang's description. 



Epidermophyton rubidmn (Priestley) Dodge, n. comb. 



TricJiophyton 7-ubidum Priestley, Med. Jour. Australia 4: 2: 474, 1917. 



Trichophyton purpureum var. II Takahashi, Jap. Jour. Derm. Urol. 25: 

 [74], 1925. 



Isolated from an extensive erythrosquamous eruption over both buttocks, 

 the inguinal region, the lumbar region, and the side of the neck. The lesion 

 was pustular in parts. Reinfected man and recovered the organism, but not 

 transmitted to animals. Healed by application of tincture of iodine. 



Aleurospores borne in compound thyrses, closterospores occasional, not 

 well developed; nodular organs occasional; chlamydospores common in old 

 cultures, very irregular in form. 



Colony creamy white, short velvet, medium not discolored, except glucose 

 agar which shows port wine discoloration, very dark under the center. 

 Nutrient agar groAvth slow, yellow, slightly reddish in the center, pleomorphic 

 degeneration early. Also some small buff flat colonies, without velvet, never 

 1 cm. in diameter. 



The position of this organism is somewhat doubtful ; while the small buff 

 colonies suggest Favotrichophyton, the pustular lesion occurring on the neck 

 as well as in the inguinocrural region and the occurrence of nodular organs 

 suggest Ectotrichophyton. The organism needs mvich further study both in 

 clinic and in culture.

Microsjiorum {Closteroaleurosporia) persicolor Guiart & Grigorakis, Lyon 

 Med. 141: 377, 1928. 



Perhaps first seen by Adamson in a palmar trichophytosis, probably of 

 tropical origin, since he mentions a peach-colored colony; first described by 

 Sabouraud from the almost glabrous chin of a young man of 20 (gonadal 

 deficiency?) and from vesiculose lesions on the palmar surface of a man of 

 45. Montpellier & Matamoros (1927) report a case involving the pubocrural 

 region. Inoculation into guinea pig very difficult; the hair and hair follicle 

 never infected in man or guinea pig.
