Trichosporum beigeli Rabenhorst, 1867. 



Synonyms. — Pleurococcus beigeli Rabenhorst, 1867; Sclerotium 

 beigelianum Hallier, 1868; Hyalococcus beigeli Schroeter, 1886; 

 Chlamydotomus beigeli Trevisan, 1889; Micrococcus beigeli Migula, 

 1900; Trichosporum beigeli Vuillemin, 1901. 



This fungus has been found in Europe several times in nodosities 

 of the hairs of the moustache. It hves parasitically under the form 

 of ovoid or polyhedral elements massed together on the surface of 

 the hair. These ovoid or polyhedral elements are much smaller 

 than those of the preceding species, their maximum diameter 

 varying between 3 and 4 It is easily cultivated on ordinary 

 media. In cultures mycelial threads are found, septate, slender 

 (1-57 to 2 /bb). In old cultures chlamydospores can be seen. 



Trichosporum ovoides Behrend, 1890. 



Found by Behrend in the nodosities present on the moustache 

 of a European patient; vegetates parasitically on the surface of

the hair under the form of ovoid elements ; 3 to 4 ^ long and to 

 2 J jbi wide. Grows easily on culture media; on potatoes the colonies 

 are white, while the medium takes a brownish-black colour. 



Trichosporum ovale Unna, 1896. 

 Found by Unna in the nodosities present on the moustache of a 

 European patient. Very similar to T. ovoides ; in cultures, however, 

 the mycelial threads are often corkscrew-like, and the spores have 

 thick walls. 



On potatoes the colonies are white-yellowish, and the substratum 

 takes a brownish-black colour. 



Trichosporum glycophile du Bois, 1910. 



Found by du Bois in a nodular affection of the pubic hairs in a 

 diabetic patient. In the nodules roundish elements, 3 to 4 were 

 present, together with a coccus. The fungus was easily cultivated 

 in symbiosis with the coccus on sugar media.
