“…Among these, it was shown that tef1 - α could successfully distinguish closely related Armillaria biological species, which has also been revealed by other researchers [ 21 – 25 ]. Based on the sequences from tef1 - α and IGS-1, a recent study by Coetzee et al [ 26 ] elucidated the phylogenetic relationships among biological species of Armillaria from China, and generally resolved four main phylogenetic groups, namely, the “ A . ostoyae ”, “ A .…”

Fungal species of Armillaria, which can act as plant pathogens and/or symbionts of the Chinese traditional medicinal herb Gastrodia elata (“Tianma”), are ecologically and economically important and have consequently attracted the attention of mycologists. However, their taxonomy has been highly dependent on morphological characterization and mating tests. In this study, we phylogenetically analyzed Chinese Armillaria samples using the sequences of the internal transcribed spacer region, translation elongation factor-1 alpha gene and beta-tubulin gene. Our data revealed at least 15 phylogenetic lineages of Armillaria from China, of which seven were newly discovered and two were recorded from China for the first time. Fourteen Chinese biological species of Armillaria, which were previously defined based on mating tests, could be assigned to the 15 phylogenetic lineages identified herein. Seven of the 15 phylogenetic lineages were found to be disjunctively distributed in different continents of the Northern Hemisphere, while eight were revealed to be endemic to certain continents. In addition, we found that seven phylogenetic lineages of Armillaria were used for the cultivation of Tianma, only two of which had been recorded to be associated with Tianma previously. We also illustrated that G. elata f. glauca (“Brown Tianma”) and G. elata f. elata (“Red Tianma”), two cultivars of Tianma grown in different regions of China, form symbiotic relationships with different phylogenetic lineages of Armillaria. These findings should aid the development of Tianma cultivation in China.

“…ostoyae (Hanna, Klopfenstein, Kim, McDonald, & Moore, ; Keča & Solheim, ; Kim et al., ; Pérez‐Sierra, Guillaumin, Spooner, & Bridge, ). Of late, the translation elongation factor‐1 alpha ( tef 1) region has successfully been used to distinguish Armillaria species that ITS or IGS could not separate (Antonín et al., ; Brazee et al., ; Coetzee, Wingfield, Zhao, van Coller, & Wingfield, ; Elías‐Román et al., ; Guo et al., ; Hasegawa et al., ; Klopfenstein et al., ; Maphosa, Wingfield, Coetzee, Mwenje, & Wingfield, ; Mulholland et al., ; Ota, Kim, Neda, Klopfenstein, & Hasegawa, ; Ross‐Davis, Hanna, Kim, & Klopfenstein, ; Tsykun et al., ). On the basis of a recent multilocus phylogenetic study that included tef 1, the taxonomy of some Armillaria species was revised in species that lack an annulus on the stipe.…”

Fungal species in the genera Armillaria and Desarmillaria (Physalacriaceae, Agaricales) are well known for their symbiotic relationships with Gastrodia elata and Polyporus umbellatus, important components of traditional medicine in Asia. In addition, some species in these genera cause Armillaria root disease, which has had a negative economic impact by damaging and destroying urban, horticultural and forest trees. Five species within Armillaria and Desarmillaria have been previously reported in South Korea, based primarily on basidioma morphology: A. cepistipes, A. gallica, A. mellea, A. ostoyae and D. tabescens (reported as A. tabescens). This study re‐evaluated 60 specimens of Armillaria and Desarmillaria using morphological features and molecular phylogenetic analyses of the ITS and partial translation elongation factor‐1α (tef1) sequences. In addition, spatial distributions of each Armillaria and Desarmillaria species in South Korea were determined from combined data based on basidioma collections and environmental DNA (eDNA). Six species (A. cepestipes, A. gallica, A. mellea, A. nabsnona, A. ostoyae and D. tabescens) and three lineages of A. gallica (A. gallica clade 1–3) were identified in South Korea from both specimens and eDNA. Most of the basidioma specimens used in this study were previously identified as A. mellea; however, in this study, no basidioma specimens were identified as A. mellea, although this species was detected on Jeju Island from eDNA samples. The detection of A. nabsnona was a new report for South Korea. Consistent with previous phylogenetic studies, the tef1 analysis had better resolution than the ITS analysis. These distribution data of Armillaria and Desarmillaria species will contribute to better management of Armillaria root disease as well as cultivation of G. elata and P. umbellatus in South Korea.

“…Armillaria (Basidiomycota; Physalacriaceae) is genus of approximately 40 described species of white rot pathogens that cause Armillaria root disease on hundreds of plant species (Baumgartner, Coetzee, & Hoffmeister, 2011;Guillaumin & Legrand, 2013;Raabe, 1962; Royal Horticultural Society (RHS) Advisory Service, 2015). It is a global problem: in Canada, over 200 million hectares of forests are affected by Armillaria root disease (Canadian Forest Service, 2014;Chapman & Schellenberg, 2015;Cruickshank, 2011); Armillaria infections are also reported from forests across Europe and North and South America (Brazee, Marra, & Wick, 2012;Ferguson, Dreisbach, Parks, Filip, & Schmitt, 2003;Heinzelmann, Rigling, & Prospero, 2012;Labbé et al, 2015) as well as commercial orchards and vineyards (Baumgartner, 2004;Elías-Román et al, 2013;Pellegrini, Prodorutti, & Pertot, 2014;Schnabel, Rollins, & Henderson, 2011), and Armillaria root disease is problematic in Africa, Asia, and Australasia (Coetzee, Wingfield, Zhao, Van Coller, & Wingfield, 2015;Hood, Oliva, Kimberley, Arhipova, & Bakys, 2015;Wingfield, Maphosa, Coetzee, Mwenje, & Wingfield, 2009). Ornamental plants, including herbaceous species, are also affected (Blaedow, Baumgartner, Cox, & Schnabel, 2010;Coetzee et al, 2001;Travadon et al, 2012) and in the UK the majority of enquires received by the RHS Advisory Service over the past 19 years regarding plant diseases in UK gardens have been concerning Armillaria (RHS, 2015).…”

Armillaria (honey fungus) is a virulent necrotrophic pathogen that causes Armillaria root disease. Conventional Armillaria inoculation assays use young saplings as hosts and consequently are cumbersome, frequently conducted outdoors, and take many years from establishment to analysis of infection. We have developed and evaluated a faster inoculation assay for Armillaria that uses herbaceous plants as hosts, is carried out in controlled conditions, and reduces experimental durations to 3 months. Plant species of known susceptibility to Armillaria and comparisons between virulent A. mellea and opportunistic A. gallica were used to validate the assay. Mortality and diagnostic symptoms of Armillaria root disease such as epiphytic rhizomorphs and mycelial fans were used to assess levels of infection. We also attempted to reduce assay preparation time by substituting woody inocula with agar inocula, but typical symptoms of Armillaria root disease were only observed on plants infected with woody inocula. Through our assay, we identified five new potential herbaceous hosts of Armillaria: Kniphofia hirsuta, Hordeum vulgare, Lobelia cardinalis, Nicotiana tabacum and Helenium hoopesiifurther expanding the extensive list of plants with susceptibility to Armillaria and suggesting infection of herbaceous species may be more widespread than currently acknowledged.
