  • The mycelial growths of wood-decaying mushroom strains collected from Korean forests were investigated on solid media under different culture media and temperatures. Most of strains showed the higher mycelial growth on potato dextrose agar (PDA) than malt extract agar (MEA) or sabouraud dextrose agar (SDA) plates. Except for a few strains, they grew well on PDA at $25^{\circ}C$ and showed a poor growth at low temperature ($10^{\circ}C$) than high temperature ($30^{\circ}C$). All strains showed the carboxymethylcellulase (CM-cellulase) and laccase activities on solid media containing the specific substrates for two different enzymes.

  • This study was carried out to establish a suitable method for liquid spawn production from Lentinula edodes. The optimum production of liquid spawn (OLS) was achieved using soybean meal medium (SMM) with 0.3% of 850 um oak powder and 10-day incubation period and 0.6 vvm aeration volume. OLS showed activities of laccase on ABTS agar plate and carboxymethyl cellulase (CM-cellulase) on CMC agar plate. In case of liquid spawn, fruiting-body development period was delayed approximately 1 day compared to that of sawdust spawn, however, the yield of 153 g per 1.2 kg polypropylene bag was similar to that of sawdust spawn.

  • Pleurotus species are commercially essential mushrooms and widely cultivated throughout the world. The production of Pleurotus mushrooms alone accounts for around 25% of that total cultivated mushrooms globally. In America and Europe, Pleurotus species are considered specialty mushrooms, whereas, in Korea, their cultivation is economically profitable, and it is one of the highly consumed species. Pleurotus species are predominantly found in tropical forests and often grow on fallen branches, dead and decaying tree stumps, and wet logs. Biographical studies have shown that the Pleurotus genus is among the more conspicuous fungi that induce wood decay in terrestrial ecosystems worldwide due to its formidable lignin-modifying enzymes, including laccase and versatile peroxidases. Pleurotus species can be grown easily due to their fast colonization nature on diversified agro-substrates and their biological efficiency 100%. Pleurotus mushrooms are rich in proteins, dietary fiber, essential amino acids, carbohydrates, water-soluble vitamins, and minerals. These mushrooms are abundant in functional bioactive molecules, though to influence health. Pleurotus mushrooms are finding unique applications as flavoring, aroma, and excellent preservation quality. Apart from its unique applications, Pleurotus mushrooms have a unique status delicacy with high nutritional and medicinal values. The present review provides an insight into the cultivation of Pleurotus spp. using different agro-waste as growth substances paying attention to their effects on the growth and chemical composition.

  • This study surveyed mushrooms as part of the Hallasan Natural Reserve Basic Academic Survey, which was conducted for the purposes of securing basic data on the Hallasan Mountain Natural Reserve; our study targeted the area between Seongpanak Trail and Donnaeko Trail from April to October 2018. A total of 392 species from 184 genera in 65 families were investigated. Among them, 187 mushrooms were wood-decaying species. The greatest diversity in mushroom species was recorded in July (206 species) at an altitude of 600-800 m above sea level. Among the mushrooms investigated, five were climate-sensitive biological indicator species and two were potential candidates for that classification. Of these, 163 species were biological resources that require approval for overseas export.

  • In 2017, we collected a wood-decay fungus growing on a dead and decaying herbaceous plant (Reynoutria sachalinensis (F. Schmidt) Nakai) in Dokdo, the far-eastern island of South Korea. Morphologically, this species is characterized by resupinate, coriaceous to corky basidiocarps, poroid hymenophores, pseudodimitic hyphal system, and ellipsoid basidiospores. Based on morphological observation and internal transcribed spacer of ribosomal DNA, the fungus was identified as Xylodon flaviporus (Berk. & M.A. Curtis ex Cooke) Riebesehl & Langer. It is only the second macrofungal species reported from Dokdo, and R. sachalinensis is the first herbaceous plant to be identified as a host for X. flaviporus.
