496 MEDICAL MYCOLOGY 



Spirals on Sabouraud media, easily breaking up into arthrosporea and not abundant; clostero- 

 spores not very abundant, 2-celled; nodular organs not described but perhaps 

 present; central knob surrounded by several zones; white, smooth tobacco-yellow, 

 gray granular (surface of chamois leather) then 5-6 alternating, very narrow, light 

 and dark circles and a white margin. E. circiiluscentricum. 



Spirals on all media, central eminence becoming umbilicate with powdery lanceolate rays 

 (less pronounced in maltose), reverse reddish; on conservation agar, colony re- 

 sembles lunar craters, irregular powdery. E. mentagrophytes. 

 Morphology unknown. 



With very slender rays, yellowish brown, pleomorphism not observed. 



var. chibaense. 

 With fine radial striations, rose red, becoming reddish brown; reverse rose; on conserva- 

 tion agar short, thick velvet, white. E. ehimeense. 

 Without rays ; reddish with white downy margin, reverse deep dark brown, pleomorphism in 

 40 days, medium dark red; on conservation agar, snow white, with thin yellowish 

 center; reverse not colored. E. Kagawaense. 

 Central knob purple lake, covered with a creamy white powder, probably of mouse origin, 

 Australia. E. rodens.

Producing an epizootic in horses (first on 800 horses at Sedan) , one slight 

 lesion in man. Dalla Favera also reports a case in a human being. Pautrier 

 & Rietman (1922) report an epidemic of 100 cases due to this organism in 

 Strasbourg, but the organism is not carefully described. In 1924 they report 

 a laboratory infection from washing tubes containing year-old cultures. Per- 

 haps their cases should be referred to E. eriotrephon or E. lacticolor. Easily 

 inoculable into guinea pig. According to various reports, it spread to Ger- 

 many after the World War, but is apparently dying out in that region. Quite 

 probably these reports should be referred to E. eriotrephon, from the descrip- 

 tions of their organisms. Also reported from Poland, Manchuria, Japan, and 

 Sao Paulo in Brazil. Neither unnamed variety, described by Ballagi (1926) as 

 belonging to this species, should be referred here. 



Chlamydospores present, often several in a dense group, suggesting nodu- 

 lar organs but less highly developed than in E. lacticolor; spirals, clostero- 

 spores 7-8-celled, and racquet mycelium not reported by Sabouraud but found 

 by various authors on other media, especially polysaccharides, often rare ; 

 aleurospores typical.
