  • Oak wilt disease caused by Raffaelea quercus-mongolicae has emerged obviously in Korea. We selected antifungal isolates against R. quercus-mongolicae among 368 endophytic fungal isolates from different parts of oak and pine trees. The experiment was conducted in the primary and secondary screenings by dual culture test. The antifungal activity of the selected isolates was assessed in culture filtrate test based on the inhibition rates in mycelial growth, sporulation, and spore germination of oak wilt fungus. Five isolates, E089, E199, E282, E409 and E415, showed strong antifungal activity in culture filtrate test, and their antifungal activity decreased on the culture media supplemented with heated culture filtrate. Higher mycelial growth inhibitions on the unheated media were recorded in E409 (Colletotrichum acutatum), E089 (Daldinia childiae), E415 (Alternaria alternata) and E199 (Daldinia childiae) with the inhibition rates of 79.0%, 70.1%, 68.9% and 64.5%, respectively. These isolates also had the higher sporulation inhibitions on unheated media with the rates of 96.8%, 84.2%, 82.8% and 80.5%, respectively. The spore germination of the oak wilt fungus was completely inhibited by E282 (Nectria balsamea) on both unheated and heated media. These results showed that a higher number of potent antifungal isolates against oak wilt fungus was isolated from the petiole compared to the other parts. This study could contribute to the development of biological control approaches for the management of oak wilt disease caused by R. quercus-mongolicae.

  • Until recently, many scientific names of Korean Aphyllophorales have been used in a state of confusion. Korean names of Aphyllophorales species recorded until recently were listed here and, among them, 40 misnamed species were renamed according to The Proposal for the Unification of Korean Names for Mushrooms recommended by the Korean Society of Mycology in 1978. This list contains rearranged 411 species of 144 genera from 23 families in Korean Aphyllophorales.

  • During the study of mushroom flora in Hongneung Arboretum, Ileodictyon gracile was confirmed as new to Korea and described based on morphological and microscopic characteristics in here. This species has subhypogeous, clathrate structure, and obovoid spores. The clathrate structures have $4{\sim}12$ polygonal meshes.

  • A mushroom survey was conducted in Mt. Cleopatra Needle Forest Reserve (CNFR) northeast of Puerto Pincesa, the capital city of Palawan island, from August 2018 to September 2019. During this period, 433 fungal fruiting bodies were collected from 3 different from survey sites, Concepcion, Kalakwasan, and Tanabag Barangays. The specimens were identified based on their morphological and molecular analyses and classified into 176 species, 114 genera, 55 families, and 22 orders. The mushrooms belong to Ascomycota were classified into 20 species, 15 genera, 12 families, and 7 orders, while those belongs to Basidiomycota were classified into 156 species, 99 genera, 43 families, and 15 orders, respectively. Among these mushrooms, the families with high frequency were Polyporaceae (18.9%), Marasmiaceae (11.5%), Xylariaceae (9.7%), Agaricaceae (8.3%), Auriculariaceae (4.8%), Ganodermataceae (4.2%), Hypoxylaceae (3.2%), and Sarcoscyphaceae (3.0%), and comprised 63.7% of the total specimens identified. This report may be the first checklist of mushrooms in Mt. CNFR and could be used for developing conservation strategies of the critical habitat in Palawan island.

  • Interspecific heterokaryons were obtained by polyethylene glycol induced fusion of protoplasts from auxotrophic mutants of P. ostreatus+P. cornucopiae, P. ostreatus+P. florida, P. ostreatus+P. sajor-caju, P. florida+P. cornucopiae, P. florida+P. sajor-caju and P. sajor-caju+P. cornucopiae protoplasts. The Fusion products of protoplasts were induced by MCM+benomyl, but segregation of sectors were not identified. Interspecific fusion products of protoplasts between incompatible strains did not form true clamp connections and did not produce fruit bodies. For induction of fertility, interspecific heterokaryons crossed with their parents by hyphal anastomosis.
