The one strain of Aspergillus glaucus with large ascospore (7.5 to 8.5 u by 5.5 u) was isolated from Yokan and examined the physiological and morphological natures. Physiologically, it was more osmophill than Aspergillus flavus LINK as a control fungi (Table 1), and the osmophility (Table 2), pigment which was produced by aerial hyphae surrounding perithecia (Fig. 1), and optimum temperature for growth (Table 3) was equal to that of Aspergillus medics. 32-2. Morphologically, it was synonymus with Aspergillus medius 32-2 and Aspergillus carnoyi THOM and RAPER, but there were some difference between Aspergillus medius MEISS. and these three strains (Table 4). However, as it was conciderd that these morphological natures, except with conidia and ascospores, vary with cultural condition, especially with osmotic pressure on medium. So this strain of HFES No. 187 was classified as Aspergillus glaucus var. minor according to NEHIRAs classification of Aspergillus glaucus group depending on the dimention of ascospore.
