thick white duvet. Related varieties are also found which form 

 huge crateriform colonies. 



The cultures form no conidia but are readily identified by the 

 innumerable blunt fuseaux which are born on aerial hyphge. These 

 are often in clusters which have been compared to a hand of 

 bananas. Older cultures show also many intercalary chlamydospores. 

 The fuseaux are not found in cultures which have become downy.

TINEA VERSICOLOR 



(Pityriasis versicolor, Chromophytosis) 



Tinea versicolor appears as large fawn-colored patches on the 

 covered parts of the body. These show slight superficial scaling

 abundantly in the horny epidermis where it seems to grow as a 

 saprophyte.
