134 MEDICAL MYCOLOGY 



Nodules on the hair, large ovoid or fusiform ; asci 35-40/* long, only 4- 

 spored; ascospores 25-30 x 10-14/* very thick-walled, lacking filiform append- 

 ages but ending in long slender points up to 10-12/* long, often somewhat 

 curved. 



Not cultivated. 



Species of Doubtful Position 



The following species are rather imperfectly described and may belong 

 elsewhere, although they were placed here by the original authors. In some 

 cases I have been unable to locate the original description and know the name 

 only by a brief mention in the literature. 



Trichospomm Beig-elii (Rabenhorst) Vuillemin, Arch, de Parasitol. 5: 

 38-66, 12 figs., 1902. 



Pleurococcus Beigeli Klichenmeister in Rabenhorst, Hedwigia 6: 49, 1867. 



Sclerotium Beigelianum Hallier, Paras. Unters. 75, PI. 2, Figs. 24, 25, 1868. 



Zoogloea Beigeliana Eberth, Centralbl. Med. Wiss. 11: 307, 1873. 



Hyalococcus Beigeli Schroeter, Kryptog. Fl. Schlesien 3: 152, 1886. 



Chlamydotomus Beigeli Trevisan in Saccardo, Syll. Fung. 8: 1042, 1889. 



Micrococcus Beigeli Migula, Syst. Bakterien, 1: 193, 1900. 



Attacking the hair in wigs and switches, Germany. Vuillemin (1902) 

 isolated what he called this fungus from the hairs of the moustache. The 

 report of this fungus from pubic hair in Nigeria by Manson-Bahr (1932) 

 probably should be referred to Favotrichophyton. 



Cells 3-5/t in diameter, spherical or angular by mutual pressure, surround- 

 ing the hair in a spherical mass of gel ; sporangia mostly 1/* thick, containing 

 12-20 spores. 



Vuillemin describes the fungus isolated by him as follows: Cells 2.5-4/*, 

 mostly 3-4/*, wall thick, held together by gelification of the outer layer of the 

 wall. Larger chlamydospores in the interior of the stroma, 6/* in diameter. 



On maltose agar, gelatin, carrot, beet, and potato, a yellowish gray, humid 

 colony, becoming convoluted, surface drying chalky white. Cells cylindric, 

 4-5/* in diameter, forming a more or less dichotomous mycelium about 2/i in 

 diameter, producing hypnospores filled with reserves up to 12/* in diameter. 

 Gelatin and serum not liquefied. Producing a pellicle on the surface of liquid 

 media, growth suggesting- that of Geotrichum lactis. 



Trichospomm ovale Paoli, Giorn. Ital. Mai. Ven. Pelle 54: 566-572, 1913, 

 non Unna ap. Vviillemin 1902. 



Isolated from infected hairs of the moustache with the usual trichosporic 

 nodules, hair not breaking readily. 



Spores in nodules 3-4/i, hyphae present. In cultures, mycelium of branched, 

 septate hyphae bearing terminal chains of spores often suggesting clostero- 

 spores. Not pathogenic for guinea pig or rabbit. 



On Sabouraud agar, colony whitish, moist, radially furrowed, slightly 

 velvety, becoming yellowish. On gelatin, colony similar but growth much
