2. Discomyces madurcB. (Mycetoma). Causes the cattle disease 

 known as madura foot, which can be transmitted to man. Essentially a 

 tropical disease. Two varieties (black and white) of the disease are 

 reported.

Fig. 73. — -Three terminal hypae showing the characteristic spore formation of Peni- 

 cillium glaucum. This fungus is a true saprophyte and is never found on living fruits or

4. Microsporoides minutissimus. Causes a skin disease known as 

 Erythrasma or Dhobie's itch. Found in the tropics. 



5. Trichosporum giganteum. Causes a disease of the hair. The 

 spores of the fungus are arranged about the hair in a peculiar mosaic.
