Normally causing favus about the head of the turkey and domestic fowl, but 

 inoculable into man and rarely occurring spontaneously. The disease was 

 first described by Gerlach (1858-59) and F. Miiller (1858). First cultivated 

 by Duclaux (Megnin 1890) and first thoroughly described culturally by Sab- 

 razes (1893). (See also Costantin & Sabrazes 1893 and Costantin 1893.) Arti- 

 ficial inoculation on man did not produce typical favic lesions, hence this 

 organism was long confused by Sabouraud and others with Megatrichophyton 

 roseuni which also infects the head of fowl. In badly infected poultry houses 

 the disease sometimes extends to the feathered areas, causing the loss of feathers 

 over the infected areas and leaving scutula. On man, the experimental lesions 

 tend to disappear spontaneously by the seventeenth day, although small 

 scutula are produced. Also inoculable into guinea pigs and white mice. Com- 

 mon in France, occasional in Germany, rare in Brazil. 



Clostrospores 1-6-celled, either lateral or terminal, with few aleurospores ; 

 spirals on dextrin + peptone agar. 



On Sabouraud glucose, small round disc, short velvet, pure white, having a 

 small central button with a small cup. At 30° C, pale rose, umbilicate, with 

 eerebriform convolutions and cracks in age. Divided into sectors by radial 

 folds, rose pigment diffusing into the medium, the only member of this genus 

 in which this is reported. The amount of pigment varies, in some colonies 

 being a deep raspberry color. 



On Sabouraud conservation agar, it retains its platelike appearance with 

 a slight concavity and three or four very fine concentric folds. On potato, 

 surface irregular, white, with small cracks or irregular furrows, yellowish in 

 color. On milk, peptonization incomplete with a vermilion floating colony. 

 Readily differentiated from M. rosexim by its more rapid growth, flatter 

 colony and pigment diffusing into the medium. The latter has a gooseberry 

 violet reverse with a black spot in the center, and the pigment does not diffuse.
