ASCOMYCETES AND BASIDIOMYCETES 



Penieillium brevicaule var. hominis Brumpt and Langeron, 1910, 

 Found by Brumpt and Langeron in two cases of onychomycosis. 

 In the lesions septate mycehal threads were seen, 2 to 16 ./^"in 

 diameter, and large groups of chlamydospores, generally termmal, 

 10 to 30 fi in diameter. The fungus is easily cultivated on Sabou- 

 raud's agar and other sugar media, also on potatoes and carrots. 

 Optimum temperature 25° C, but grows well also at 37° C. Conidia 

 spherical or occasionally ovoid, of a chocolate colour.

Penieillium barbae Castellani, 1907. 



Found by us growing on the beard of natives of equatorial Africa, and in 

 natives of Ceylon. 



Penieillium pruriosum Salisbury. 

 Doubtful species found by Salisbury in the vaginal mucus of a woman 

 suffering from intense vaginal pruritus. 



Genus Aspergillus Micheli, 1725. 



The conidiophore hyphse are not ramified, and terminate into 

 ovoid or roundish formations, which support numerous claviform 

 elements (sterigmata), each of which sup- 

 ports a chain of roundish conidia. 



Aspergilli are generally saprophytes, 

 but they may become parasites. They 

 are easily grown on acid media, liquid or 

 solid, and also on alkaline media. Iron and 

 manganese have a favourable influence on 

 the growth and sporulation of these fungi. 



A medium much used is Raulin's liquid, the 

 formula of which is: Cane-sugar, 70 grammes; 

 tartaric acid, 4 grammes; ammonium nitrate, 

 4 grammes; ammonium phosphate, 0 60 gramme; 

 potassium carbonate, o-6o gramme; magnesium carbonate, 0-40 gramme; 

 ammonium sulphate, 0-25 gramme; zinc sulphate, o 07 gramme; ferrous 

 sulphate, 0-07 gramme; potassium silicate, 0-07 gramme. 



Fungi of the genus Aspergillus, when growing parasitically in the 

 tissues, often lose their characteristics; the typical fructifications
