Abstract
- We report the fruiting-body formation and cultivation properties of Asterophora lycoperdoides, a fungicolous fungus. Asterophora lycoperdoides formed fruiting bodies on potato dextrose agar medium in approximately 1 week, although this fungus shows high host specificity to Russula nigricans in nature. Optimal temperature of mycelial growth and fruiting-body formation was 25°C. Mannitol or soluble starch was preferably used as a carbon source, and amino nitrogen was preferably used as the nitrogen source. For a better understanding of the relationship between A. lycoperdoides and R. nigricans, we cultivated A. lycoperdoides on media supplemented with freeze-dried fruiting bodies of various fungi. The germination rate was approximately 2.5 times higher on the medium containing freeze-dried R. nigricans than that on the PDA medium. The mycelia extended most rapidly in the presence of R. nigricans. Furthermore, the stipe length of its fruiting body was the longest on the medium containing R. nigricans. These results indicated that A. lycoperdoides can grow faster by utilizing certain substances that are abundantly contained in R. nigricans, such as mannitol, or by utilizing R. nigricans itself. It is considered that the constituents of R. nigricans might contribute to the host specificity of A. lycoperdoides. [ABSTRACT FROM AUTHOR]
