TORULEAE 673 



Whole mycelium not breaking up into arthrospores ; chains of arthrcspores borne on short 

 lateral branches. 

 Arthrospores ellipsoid to spherical. 



Spores rough. Jremispora (see p. 182). 



Spores smooth. D'lmatium. 



Arthrospores 2-celled. Cladofporium. 



Arthrospores not produced, mycelium tending to form sclerotia, chlamydospores abundant, 

 strictly pathogenic, producing mycetomata. 

 Mycelium dark gray to black. Madurella. 



Mycelium remaining white. Indiella. 



CONIOSPORIUM 



Coniosporium Link, Mag. Ges. Natiirf. Freunde Berlin 3: 8, 1809. 

 The type species is Coniosporium olivaceum Link on Pimis maritima. 

 Mycelium scanty, conidiophores hyaline, short, quickly evanescent ; co- 

 nidia spherical to ovoid or lenticular, dark. 



Coniosporium onychophilum* Agostini, Boll. Sez. Ital. Soc. Internat. Mi- 

 crobiol. 3: 214, 215, 1931. 



Isolated from lesions of the nails, Italy (case of Tarantelli). Not patho- 

 genic for white mice. 



Mycelium dimorphic, some hyphae 2-2.5/x with refractive granules hyaline, 

 little branched and irregularly septate, other hyphae 6-7.5/^ with oil droplets, 

 a yellow brown pigment and regularly septate. Arthrospores lenticular, face 

 view circular, 8-12fx in diameter; girdle view fusiform, 8-12 x 4-5/x; occasionally 

 somewhat ellipsoid, 10-12 x 5-7/*. Epispore olivaceous or brown-olivaceous, 

 contents granular, oily, hyaline. On treatment with acid, the wall splits into 

 two halves. 



On Pollacci agar, carrot, and potato, colonies floccose, lanuginose, at first 

 white then rose color at the surface and hazel below in the substrate. On 

 Sabouraud agar, colonies less floccose, substrate browning. No growth on 

 blood agar. On Raulin's solution, colonies floating, slightly floccose, rose at 

 first, then hazel, and finally dark brown. In glucose, maltose, and galactose, 

 colonies mucilaginous, becoming cartilaginous and dark brown. On leather, 

 colonies small, floccose, yellow. On feathers, colonies small and whitish. No 

 growth on hair. Ferments glucose, maltose and galactose within 6 days. 

 Optimum temperature between 15° and 25° C; no germination at 35° C.
