Ten New Recorded Species of Macrofungi on Ulleung Island, Korea
Ulleung Island is a biodiversity hotspot in South Korea. During a survey of indigenous fungal species from Ulleung Island conducted from 2015 to 2016, we discovered 10 unrecorded macrofungi in Korea. These macrofungi were identified to the species level using morphological features and phylogenetic analysis based on the internal transcribed spacer region: Deconica phyllogena, Mycena zephirus, P...
متن کاملGeophysical Tomography for Imaging Water Movement in Welded Tuff-
Alterant tomography h*s been evaluated for its ability to de lineate itfsitu water flow paths in a fractured welded-tuff rock mass, The evaluation involved a field experiment in which tomographs of electromagnet attenuation factor (or attenuation rate) at 300 MHz were made before, during, and after the introduc tion to the rock of two different water-based tracers: a plain water and dye solut...
متن کاملA New Record of Penicillium raphiae Isolated from Agricultural Soil of Ulleung Island, Korea
A fungal isolate EML-NCP01 was recovered from agricultural soil in Ulleung Island, Korea. Phylogenetic analysis of internal transcribed spacer and β-tubulin genes identified the isolate as the Penicillium species P. raphiae. Morphologically, the EML-NCP01 isolate was identical to the previous description of P. raphiae. The species presented here has not been reported in Korea.
متن کاملThree New Recorded Species of the Physalacriaceae on Ulleung Island, Korea
Most known species in the Physalacriaceae are saprotrophs that grow on decaying leaves and wood, and approximately 21 genera in the Physalacriaceae have been reported worldwide. During an ongoing survey of indigenous fungi in Korea, four specimens belonging to the Physalacriaceae were collected on Ulleung Island. These specimens were identified as three species based on morphological characteri...
