Unexpected diversity of basidiomycetous endophytes in sapwood and leaves of Hevea
2016Co-Authors: Rachael Martin, Demetra Skaltsas, Romina Gazis, Priscila Chaverri, David S HibbettAbstract:Abstract: Research on fungal endophytes has ex-panded dramatically in recent years, but little is known about the diversity and ecological roles of endophytic basidiomycetes. Here we report the analysis of 310 basidiomycetous endophytes isolated from wild and planted populations of the rubber tree genus, Hevea. Species accumulation curves were nonasymptotic, as in the majority of endophyte surveys, indicating that more sampling is needed to recover the true diversity of the community. One hundred eighteen OTUs were delimited, represent-ing nine orders of Basidiomycota (Agaricales, Athe-liales, Auriculariales, Cantharellales, Hymenochae-tales, Polyporales, Russulales, Septobasidiales, Tremellales). The diversity of basidiomycetous endo-phytes found inhabiting wild populations of Hevea was comparable to that present in plantations. However, when samples were segregated by tissue type, sapwood of wild populations was found to contain a higher number of species than sapwood of planted trees. Seventy-five percent of isolates were members of the Polyporales, the majority in the phlebioid clade. Most of the species belong to clades known to cause a white-rot type of wood decay. Two species in the insect-associated genus Septobasidium were isolated. The most frequently isolated genera included Bjerkandera, Ceriporia, Phanerochaete, Phle

A phylogenetic overview of the Agaricomycotina.
Mycologia, 2006Co-Authors: David S HibbettAbstract:The Agaricomycotina contains about one- third of the described species of Fungi, including mushrooms, jelly fungi and basidiomycetous yeasts. Recent phylogenetic analyses by P. Matheny and colleagues combining nuclear rRNA genes with the protein-coding genes rpb1, rpb2 and tef1 support the division of Agaricomycotina into Tremellomycetes, Dacrymycetes and Agaricomycetes. There is strong support for the monophyly of the Tremellomycetes, and its position as the sister group of the rest of the Agaricomycotina. Dacrymycetes and Agaricomycetes also are supported strongly, and together they form a clade that is equivalent to the Hymenomycetidae of Swann and Taylor. The deepest nodes in the Agaricomycetes, which are supported only by Bayes- ian measures of confidence, suggest that the Sebaci- nales, Cantharellales and Auriculariales are among the most ancient lineages. For the first time, the Polyporales are strongly supported as monophyletic and are placed as the sister group of the Thelepho- rales. The Agaricales, Boletales and Atheliales are united as the Agaricomycetidae, and the Russulales might be its sister group. There are still some problematical nodes that will require more loci to be resolved. Phylogenomics has promise for recon- structing these difficult backbone nodes, but current genome projects are limited mostly to the Agaricales, Boletales and Polyporales. Genome sequences from other major lineages, especially the early diverging clades, are needed to resolve the most ancient nodes and to assess deep homology in ecological characters

first successful domestication and determination of nutritional and antioxidant properties of the red ear mushroom auricularia thailandica Auriculariales basidiomycota
Mycological Progress, 2017Co-Authors: Asanka R Bandara, Peter E Mortimer, Kevin D Hyde, Samantha C Karunarathna, Sehroon Khan, Pattana KakumyanAbstract:In order to fulfill the increasing demand for edible mushrooms and maintain a steady supply throughout the year, it is necessary to domesticate new wild edible mushroom species. In this study, we domesticated Auricularia thailandica, a newly identified edible species that was collected from the wild in Thailand. We compared the growth of A. thailandica in three different growth media: sawdust, wheat husk and sugarcane bagasse. The use of sawdust resulted in the fastest rate of mycelial colonisation at 56.4 +/- 1.2 days, pinheads were formed in 14.2 +/- 0.4 days and the biological efficiency was 17.1 +/- 2.8%. Nutritional analysis showed that A. thailandica contained a higher proportion of protein (12.99 +/- 0.05%) and fat (2.93 +/- 0.66%) by dry weight than other commercial Auricularia spp. available on the market. The antioxidant potential of A. thailandica varied with the extraction solvent used, and the effective concentration was found to be significantly lower in methanol extract than aqueous extract. Additionally, this species has an attractive reddish orange colour and larger basidiocarps than other commercially available species.

diversity of auricularia auriculariaceae Auriculariales in thailand
Phytotaxa, 2017Co-Authors: Asanka R Bandara, Alan J L Phillips, Peter E Mortimer, Pattana Kakumyan, Jianchu Xu, Samantha C Karunarathna, Kevin D HydeAbstract:The identification of Auricularia species has previously relied on the examination of macroscopic features of mushroom samples collected in Thailand. These features may vary with age, light exposure, moisture and other factors, making such identification prone to error. This study uses morphological characteristics and molecular data to improve upon previous classifications of Auricularia species. Fruiting bodies collected during recent field excursions and previous collections from herbaria were examined and sequenced for two loci, viz. ITS and rpb2. Auricularia asiatica is described as a new species based on both morphological characteristics and molecular data, and is introduced with a full description, illustrations and colour photographs. Auricularia cornea and A. villosula are described as new records from Thailand. A combined ITS and rpb2 phylogenetic tree is provided, showing the placement of five Auricularia species found in Thailand.

Global diversity and taxonomy of the Auricularia auricula-judae complex (Auriculariales, Basidiomycota)
Mycological Progress, 2015Co-Authors: Fang Wu, Asanka R Bandara, Shuang-hui He, Vera F. Malysheva, Kevin D Hyde, Yuan Yuan, De-wei LiAbstract:Auricularia auricula-judae was previously considered a single species, but was recently demonstrated to be a species complex. The economically important, cultivated Auricularia mushrooms are included in the complex. Two species are cultivated, but have been treated as a single species: A. auricula-judae. Fifty samples of so-called A. auricula-judae from Asia, Europe, and North America were analyzed using morphology and molecular phylogeny. Phylogenetic analyses were carried out by ITS sequence and combined ITS, LSU, and rpb2 sequence, and 16 ITS, 16 LSU, and 16 rpb2 sequences were newly generated. Seven species in the complex were delineated, including three species new to science: Auricularia angiospermarum, A. minutissima, and A. tibetica. Illustrated description of the three new species and discussions in relation to other species are introduced in this paper. Auricularia heimuer is the most extensively cultivated species of Auricularia. Auricularia villosula is also cultivated, but has been named by the mushroom production industry A. heimuer. The size of basidiospores and presence or absence of medulla are important characters for differentiating the species within the complex, and ITS sequence data is a sensitive marker to discriminate species. A synoptic table of comparison of species in the complex is provided including the most important characters of the seven species.

Auricularia thailandica sp. nov . ( Auriculariaceae , Auriculariales ) a widely distributed species from Southeastern Asia
Phytotaxa, 2015Co-Authors: Asanka R Bandara, Kevin D Hyde, Samantha C Karunarathna, Jie Chen, Pattana KakumyanAbstract:Auricularia is an important genus among the jelly fungi due to its popular consumption and medicinal properties. A new species of Auricularia , A. thailandica is described from fresh collections made from the Philippines, Thailand and Southern China based on morphological and molecular characters. Auricularia thailandica differs from other species by having short and loosely arranged abhymenial hairs on the basidiomata and in the different size of the zones in a cross section of the basidiomata. The species is found to be widely distributed in Southeastern Asia. Phylogenetic relationships were inferred based on the nuclear ribosomal internal transcribed spacer (ITS) region. The new species is introduced with full description and illustrations.

On Protomerulius and Heterochaetella (Auriculariales, Basidiomycota)
Mycological Progress, 2019Co-Authors: Viacheslav Spirin, Renato Lúcio Mendes Alvarenga, Josef Vlasak, Otto Miettinen, Tatiana Baptista Gibertoni, Leif Ryvarden, Vera Malysheva, Karl-henrik LarssonAbstract:The taxonomy of Protomerulius and Heterochaetella is revised based on DNA data and morphological evidence, and their type species, P. brasiliensis and H. dubia , are proved to be congeneric. As a consequence, H. dubia and related species, of which four are described as new, are placed in Protomerulius . Heterochaete microspora is also combined in Protomerulius , and the genus concept is redefined to encompass effused species with smooth or spiny hymenophore and monomitic hyphal structure. Psilochaete multifora , gen. and spec. nov. is a distant relative of Protomerulius spp. found in Norway. Heterochaetella cystidiophora is re-collected in Brazil and placed in the synonyms of Heterochaete sanctae-catharinae . This species does not belong to the Protomerulius–Heterochaetella lineage, and it is transferred to Metulochaete , gen. nov.

Studies in the Stypella vermiformis group (Auriculariales, Basidiomycota)
Antonie van Leeuwenhoek, 2019Co-Authors: Viacheslav Spirin, Vera Malysheva, Danny Haelewaters, Karl-henrik LarssonAbstract:Stypella vermiformis is a heterobasidiomycete producing minute gelatinous basidiocarps on rotten wood of conifers in the Northern Hemisphere. In the current literature, Stypella papillata , the genus type of Stypella (described from Brazil), is treated as a taxonomic synonym of S. vermiformis . In the present paper, we revise the type material of S. papillata and a number of specimens addressed to S. vermiformis . As a result, the presumed synonymy of S. papillata and S. vermiformis is rejected and the genus Stypella is restricted to the single species S. papillata . Morphological and molecular phylogenetic studies of specimens from the Northern Hemisphere corresponding to the current concept of S. vermiformis uncovered three species from two newly described genera. S. vermiformis s.str. is distributed in temperate Europe and has small-sized basidia and basidiospores, and it is placed in a new genus, Mycostilla . Another genus, Stypellopsis , is created for two other species, the North American Stypellopsis farlowii , comb. nov., and the North European Stypellopsis hyperborea , sp. nov. Basidia and basidiospores of Stypellopsis spp. are larger than in Mycostilla vermiformis but other morphological characters are very similar. In addition, Spiculogloea minuta (Spiculogloeomycetes, Pucciniomycotina) is reported as new to Norway, parasitising basidiocarps of M. vermiformis and Tulasnella spp.

Revision of Protohydnum (Auriculariales, Basidiomycota)
Mycological Progress, 2018Co-Authors: Vera Malysheva, Viacheslav Spirin, Viviana Motato-vásquez, Otto Miettinen, Jaya Seelan Sathiya Seelan, Karl-henrik LarssonAbstract:Three species currently addressed to Protohydnum ( Auriculariales ) are studied with morphological and DNA methods. The genus Protohydnum is retained for the type species only, P. cartilagineum , recently re-collected in Brazil. The European species, P. piceicola , is not congeneric with P. cartilagineum and, therefore, placed in its own genus, Hyalodon , gen. nov. Another Hyalodon species, H. antui , is described from East Asia. The third member of Protohydnum sensu lato, P. sclerodontium from South-East Asia, is transferred to Elmerina .
