This study aimed to characterize the mycelial morphologies of Hericium erinaceus isolates, including 18 wild-type collections and cultivatable species 'Noru 1' and 'Noru 2', in Korea. The morphological characteristics were used to classify the species based on aerial or branched mycelia and their brownish or whitish colors when grown on potato dextrose agar. Of the wild-type collections, the isolates KFRI 509, KFRI 1091, KFRI 1093, and KFRI 1623 showed faster mycelial growth than the cultivars 'Noru 1' and 'Noru 2'. Moreover, 60% ethanol extracts of the fruiting body of the mushroom showed the highest phenol content and DPPH and ABTS radical scavenging activity. The DPPH and ABTS radical scavenging activities of KFRI 507, KFRI 508, KFRI 842, and KFRI 1623 were 10-60% higher than those of 'Noru 1' and 'Noru 2', depending on the extract concentrations. Thus, results suggest that these wild-type collections could be useful for breeding genetic sources or processed food materials with high antioxidant activity.

Wild-type isolates of H. erinaceus were collected from different geographical areas of Korea. Nineteen isolates were cultured on mushroom substrate for producing fruiting bodies. Of these, 14 isolates formed pinheads and fruiting bodies on the substrate. The morphological and cultivation characteristics of fruiting bodies were categorized by pinheading, fruit body formation, spine types, fresh weights, and colors. Microstructures, including spines, spores, and basidia on the fruiting bodies were observed using scanning electron microscopy. The H. erinaceus isolates demonstrated different PCR polymorphisms produced by universal fungal primers (UFPs) and were classified into four groups based on their high genetic diversity.

Phenotypes of panicle, hull and seed of mutant rice (Oryza sativa L.) were characterized. Panicle mutants were classified in 4 groups with their internode length of main rachis, primary rachis, secondary rachis and pedicel. Hull and seed mutants were grouped into 12 based on their mutant characters in shape, size and color of seeds. These natural and spontaneous mutant collections showed distinct phenotypes to wild type rice. This might be useful for the identification of the functions of genetic factors in the Mendelian inheritance.
