... Ceriporia alachuana and Ceriporia nanlingensis are commonly isolated from pinewood (Dai, 2012). Other observed species were all commonly found in decaying pinewood (Lee and Jung, 2006;Wooding et al., 2013;Jang et al 2016). ...
Interaction between fungi and insects such as ants, beetles, wasps and termites inhabiting dead pine trees has significant ecological implication in the forest as they can decompose wood debris and add nutrients to the soil; however, only scarce information is available regarding the interaction between wood-decaying fungi and ants. We investigated wood-decaying fungi co-occurring with ants in dead pine trees of South Korea. A total of 57 pairs of wood-decaying fungi and ants were collected from 11 localities. 30 species of wood-decaying fungi and 14 species of ants were identified based on morphology and molecular analysis. Fungal species belonging to Trichaptum, Xylodon, Hyphodontia, and Ceriporia were dominant and co-occurred with common ant species of Lasius, Camponotus, Pristomyrmex, and Crematogaster across most of the sampling sites. This study provides a new baseline in unravelling the complex interaction between wood-decaying fungi and ants in forest ecosystems.
... The most likely placement of this mycobiont is in the Hymenochaetales, and it represents the first example of an ericoid mycorrhizal fungus in this order. Kurtia argillacea is a taxonomically broad taxon, which is relatively common in temperate and boreal forests of Europe, Asia and northern America (Bernicchia & Gorj on 2010;Gilbertson et al. 1975;Lee & Jung 2006) and its mycorrhizal potential should be further investigated. The taxonomy of Agaricomycetes often relies on nuc-rDNA which is usually the only available locus. ...
The nuclear ribosomal DNA (nuc-rDNA) is widely used for the identification and phylogenetic reconstruction of Agaricomycetes. However, nuc-rDNA-based phylogenies may sometimes be in conflict with phylogenetic relationships derived from protein coding genes. In this study, the taxonomic position of the basidiomycetous mycobiont that forms the recently discovered sheathed ericoid mycorrhiza was investigated, because its nuc-rDNA is highly dissimilar to any other available fungal sequences in terms of nucleotide composition and length, and its nuc-rDNA-based phylogeny is inconclusive and significantly disagrees with protein coding sequences and morphological data. In the present work, this mycobiont was identified as Kurtia argillacea (= Hyphoderma argillaceum) residing in the order Hymenochaetales (Basidiomycota). Bioinformatic screening of the Kurtia ribosomal DNA sequence indicates that it represents a gene with a non-standard substitution rate or nucleotide composition heterogeneity rather than a deep paralogue or a pseudogene. Such a phenomenon probably also occurs in other lineages of the Fungi and should be taken into consideration when nuc-rDNA (especially that with unusual nucleotide composition) is used as a sole marker for phylogenetic reconstructions. Kurtia argillacea so far represents the only confirmed non-sebacinoid ericoid mycorrhizal fungus in the Basidiomycota and its intriguing placement among mostly saprobic and parasitic Hymenochaetales begs further investigation of its eco-physiology.
... The polypore genus Abundisporus [1] is characterized by resupinate to pileate fruibodies with pale umber to deep purplish brown or greyish to amber brown context; ellipsoidal, slightly thick-walled, pale yellowish and nondextrinoid basidiospores; dimitic hyphal systems with skeletal hyphae; and causing white rot [2]. This genus is mostly distributed in tropical and subtropical areas [1], but was recently found in temperate areas [3][4][5]. [3][4][5][6][7][8][9]. Phylogenetic analysis based on the internal transcribed spacer (ITS) and the 28S nuclear ribosomal large subunit (LSU) showed that Abundisporus formed a monophyletic group [10][11][12][13]. ...

... Before 2006, there were no records of Abundisporus in Korea. After detailed morphological and molecular analyses, two Abundisporus species were identified: A. fuscopurpureus [4] and A. pubertatis [8]. Both of these species were previously misidentified as Fomitopsis rosea [14], as they are superficially similar (e.g., have a purple hymenophore). ...
The polypore genus Abundisporus Ryvarden is characterized by resupinate to pileate fruitbodies with a purplish brown hymenophore, slightly thick-walled, pale yellowish and non-dextrinoid basidiospores, and causing white rot. A purple color hymenophore, an easily observable and striking character, was considered the main distinctive feature at the generic level within polypores. However, due to highly similar basidiocarp features, species identification within these purple polypores is particularly difficult. Three species of purple colored polypores have been reported in Korea (Abundisporus fuscopurpureus, A. pubertatis, and Fomitopsis rosea). Based on morphological re-examination, ecological information, and sequence analysis of the internal transcribed spacer, we showed that previous classification was incorrect and there is only one species (A. pubertatis) in Korea. We provide a detailed description of A. pubertatis in Korea, as well as a taxonomic key to distinguish wood rot fungi with a purple hymenophore.
... Abundisporus fuscopurpureus (Pers.) Ryvarden, which was reported by Lee and Jung [23], with its slightly larger pores (4~5 per mm) and slightly smaller basidiospores (3~4 × 2~2.5 µm) is different from A. pubertatis. ...
In Seoul, a majority of plant communities have undergone significant changes over the last few decades; however, how wood decay fungi have responded and adapted to the changes in vegetation remains unknown. Through an ongoing investigation of Korean indigenous fungi, ca. 300 specimens with poroid basidiocarp were collected in Seoul during 2008~2012. Morphological examination and molecular analysis using the internal transcribed spacer and nuclear large subunit ribosomal DNA region sequences helped identify 38 species belonging to 28 genera, 10 families, and 5 orders in this area. Among them, three polypores, Abundisporus pubertatis, Coriolopsis strumosa, and Perenniporia maackiae were found to be new to South Korea.
... It is not clear whether such distribution pattern was influenced by the presence of their hosts. Before this work, two other Cantharellus species reported with the same geographic distribution were C. minor and C. subalbidus (Jones et al. 1994, Hyun et al. 1998, Lee et al. 2006. As has been demonstrated by botanists and mycologists (Wu et al. 2000), these southeastern North America and eastern Asia macrofungal disjunctions are of special biogeographical interest and are expected to have individual histories. ...
A new Cantharellus species from southwestern China is described, based on morphology and DNA sequencing (LSU rDNA). The new species, C. vaginatus, can be distinguished from other chanterelles by the combination of a dark-colored flocculososquamulose pileus, a rugulose hymenophore, and thick-walled hyphae in the pileipellis. Cantharellus appalachiensis , a species originally described from southeastern North America, is newly reported from China.

Deng an illegitimate later homonym of Russula leucocarpa (T. Lebel) T. Lebel. The new geographic distribution regions are recorded for Agaricus bambusetorum, Bipolaris heliconiae, Crinipellis trichialis, Leucocoprinus cretaceus, Halobyssothecium cangshanense and Parasola setulosa. Corresponding to morphological characters, phylogenetic evidence is also utilized to place the above-mentioned taxa in appropriate taxonomic positions. The current morphological and phylogenetic data is helpful for further clarification of species diversity and exploration of evolutionary relationships in the related fungal groups.
Abundisporin A (1), together with seven previously undescribed drimane sesquiterpenes named abundisporins B−H (2−8), were isolated from a polypore, Abundisporus violaceus MUCL 56355 (Polyporaceae), collected in Kenya. Chemical structures of the isolated compounds were elucidated based on exhaustive 1D and 2D NMR spectroscopic measurements and supported by HRESIMS data. The absolute configurations of the isolated compounds were determined by using Mosher's method for 1−4 and TDDFT-ECD calculations for 4 and 5−8. None of the isolated compounds exhibited significant activities in either antimicrobial or cytotoxicity assays. Notably, all of the tested compounds demonstrated neurotrophic effects, with 1 and 6 significantly increasing outgrowth of neurites when treated with 5 ng/mL NGF.
