3 i8 MORPHOLOGY OF THE ASPERGILLACE^E. 



which are 1-2 mm. in height, develop blackish brown heads 

 (40-80 p thick), whose spherical (rarely knob-like) globules 

 (20-30 p. in diameter) are thickly covered with radially arranged, 

 conical sterigma.ta, bearing spherical conidia (4-5 p thick), covered 

 with tiny wart-like protuberances. No perithecia have been 

 observed up to the present. This species saccharines starch 



FIG. 172. Aspergillus luclmensis. 

 Conidiophores and conidia. Approx. 

 magn. of i, 300 ; of 2, 1000. (After 

 Inui.) 



FIG. 173. Aspergillus Tokelau. 

 Conidiophores of different sizes from 

 diseased liuman skin. Approx. magn. 

 300. (After Wehmer.) 



in which respect it deserves further investigation and is very 

 similar to A. Wentii, apart from its colour and somewhat smaller 

 dimensions. The optimum temperature of growth is between 

 30 and 35 C. 



Associated with this species in Awamori koji, INUI (III.) found 

 another, which is morphologically analogous, but of a greyish 

 brown colour (A. pemiciosus), which, however, is merely regarded 

 as an impurity, and is subordinate, or entirely absent, in good 

 koji. 



Aspergillus Tokelau, Wehmer. This species was discovered by 

 TRIBONDEAU (I.) in the infectious " Tokelau " or Samoa disease, 

 attacking the natives of certain of the Pacific islands. It was
