Three New Recorded Species of the Physalacriaceae on Ulleung Island, Korea

Abstract

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 characteristics and molecular analysis of rDNA-internal transcribed spacer sequences. Three species in three genera were shown to be new records in Korea: Hymenopellis orientalis, Paraxerula hongoi, and Ponticulomyces orientalis. The latter two are the first records of these genera in Korea. In this study, we provide detailed morphological descriptions of these species and describe their phylogenetic position within the Physalacriaceae.

Ten New Recorded Species of Macrofungi on Ulleung Island, Korea

“…The published literature indicates that approximately 350 species have been detected from Ulleung Island [ 16 17 18 19 20 21 22 23 ]. This great diversity of fungi may be due to improved identification based on ITS sequences compared to traditional identification using solely morphological features.…”

“…Intensive surveys of macrofungi on Ulleung Island have been carried out since 1989 and 161 species have been reported [ 16 17 18 19 20 21 ]. Recently, 223 macrofungi species were reported based on morphological features and ITS sequence analysis [ 22 23 ]. Interestingly, recent studies [ 22 23 ] showed that only 27 macrofungi species overlapped, and 196 species were newly reported.…”

A new species and new records of Hymenopellis and Xerula (Agaricales, Physalacriaceae) from China

“… Petersen & Hughes (2010) revised the taxonomic relationships of the Xerula / Oudemansiella complex based on morphological evidence and molecular phylogenetic results from ITS and nrLSU. They proposed 68 new taxa, including four new genera ( Hymenopellis , Paraxerula , Pointiculomyces , Protoxerula ), accepting the definition of the genus Xerula from Yang et al (2009) , these results have been widely accepted and cited in subsequent studied ( He et al, 2019 ; Niego et al, 2021 ; Park et al, 2017 ).…”

Australasian sequestrate Fungi 20: Russula scarlatina (Agaricomycetes: Russulales: Russulaceae), a new species from dry grassy woodlands of southeastern Australia

“…The position of genera in their analyses depends upon the gene region the phylogeny is based upon. It is preferable to recognise three well supported monophyletic clades (ITS/LSU): Xerula s.str., Paraxerula, and Oudemansiella (inclusive of Hymenopellis, Protoxerula, Ponticulomyces, Dactylosporina, and Cribbea), rather than poorly supported paraphyletic clades (Park et al 2017).…”
