Article

Full-text available

Sep 2018

Abstract: This survey deals with the Xylaria taxa with penzigioid stromata, i.e., with sessile to subsessile stro- mata wider than high, collected in the French West Indies in the course of an ongoing inventorial work on the mycobiota of these islands initiated in 2003. Based on the evaluation and comparison of their morpho- logical characters, eighteen taxa are described, illustrated and commented, including seven known taxa, viz.: X. alboareolata, X. berteroi, X. boergesenii, X. flabelliformis, X. frustulosa, X. globosa and X. lechatii, only the last having been reliably reported previously from these islands. The following eight species are described as new, viz.: X. conopeicola, X. entomelaina, X. leptosperma, X. obtusispora, X. papillatoides, X. parvula, X. pelti- formis and X. rhytidosperma. The new combination X. cantareirensis is proposed for a taxon formerly placed in the obsolete genus Penzigia. The two further collections CLL 5109 and MJF 13098 that could not be unam- biguously identified are likewise described but not named, pending more material being collected. A dicho- tomous identification key and a synoptic figure plate of stromata are presented. Keywords: Ascomycota, pyrenomycetes, saproxylic fungi, taxonomy, tropical mycology, Xylariales, Xylarioi- deae. Résumé : cette étude porte sur les taxons penzigioïdes de Xylaria, c’est-à-dire à stromas sessiles à subsessiles plus larges que hauts, récoltés lors de missions d’inventaire de la fonge des Antilles françaises commencées en 2003. en se fondant sur l’évaluation et la comparaison de leurs caractères morphologiques, dix-huit taxons sont décrits, illustrés et commentés, comprenant d’une part sept taxons connus, à savoir X. alboareolata, X. berteroi, X. boergesenii, X. flabelliformis, X. frustulosa, X. globosa et X. lechatii, ce dernier seulement déjà si- gnalé des Antilles françaises. D’autre part, huit taxons nouveaux sont proposés, comprenant X. conopeicola, X. entomelaina, X. leptosperma, X. obtusispora, X. papillatoides, X. parvula, X. peltiformis et X. rhytidosperma. La nouvelle combinaison X. cantareirensis est proposée pour un taxon placé auparavant dans le genre aban- donné Penzigia. enfin, deux récoltes qui n’ont pas pu être identifiées de façon certaine, CLL 5109 et MJF 13098, sont également décrites mais ne sont pas nommées, dans l’attente de nouvelles récoltes. une clé d’identification dichotomique et une planche synoptique des stromas sont présentées. Mots-clés : Ascomycota, champignons saproxyliques, mycologie tropicale, pyrénomycètes, taxinomie, Xy- lariales, Xylarioideae.

Article

Full-text available

Mar 2024

The genus Xylaria comprises a diverse group of fungi with a global distribution and significant ecological importance, known for being a source of bioactive secondary metabolites with antibacterial, antioxidative, anticarcinogenic, and additional properties. In this study, we present a comprehensive taxonomic revision of the species of Xylaria found in some parts of southern China, characterized by an extensive multilocus phylogeny analysis based on internal transcribed spacer (ITS), TUB2 (β‐tubulin), and DNA‐directed RNA polymerase II subunit 2 ( rpb2 ) gene regions. Morphological examination and detailed comparative analyses of the collected specimens were conducted to determine the distinctiveness of each species. The multilocus phylogeny approach allowed us to infer evolutionary relationships and assess species boundaries accurately, leading to the identification of 40 novel Xylaria species hitherto unknown to science. The newly described species are: X. baoshanensis , X. bawanglingensis , X. botryoidalis , X. dadugangensis , X. doupengshanensis , X. fanglanii , X. glaucae , X. guizhouensis , X. japonica , X. jinghongensis , X. jinshanensis , X. kuankuoshuiensis , X. liboensis , X. negundinis , X. orbiculati , X. ovata , X. pseudoanisopleura , X. pseudocubensis , X. pseudobambusicola , X. pseudoglobosa , X. pseudohemisphaerica , X. pseudohypoxylon , X. puerensis , X. qianensis , X. qiongzhouensis , X. rhombostroma , X. serratifoliae , X. shishangensis , X. shuqunii , X. shuangjiangensis , X. sinensis , X. tongrenensis , X. umbellata , X. xishuiensis , X. yaorenshanensis , X. yinggelingensis , X. yumingii , X. yunnanensis , X. zangmui , and X. zonghuangii . The study's findings shed light on the distinctiveness of the newly described species, supported by both morphological distinctions and phylogenetic relationships with their close relatives. This taxonomic revision significantly contributes to our understanding the diversity of Xylaria in China and enriches the knowledge of fungal biodiversity worldwide.

AENSI Journals Advances in Environmental Biology Molecular identification and phylogeny of different macrofungi in Mt. Bangkay, Cuyapo, Nueva Ecija, Philippines based on ITS nrDNA region

Article

Dec 2016

To reveal the identification of the collected macrofungi in Mt. Bangkay, Cuyapo, Nueva Ecija, Philippines, the nuclear internal transcribed spacer region (ITS) from the total genomic DNA of the samples was amplified, sequenced and used for molecular identification and phylogeny analysis. Phylogeny matrix using Phylogeny fr., including the software default parameters such as MUSCLE for sequence alignment, PhyML for phylogeny and TreeDyne for tree rendering were used. Five mushrooms were collected in the area and were undergone molecular identification. The ITS sequence of Sample_ID_1 showed 91% identity to Microporus sp. (KJ612044.1), Sample_ID_2 had 99% to Ganoderma lucidum (HM053453.1), Sample_ID_3 had 99% identity to Meripilus giganteus, Sample_ID_4 had 100% identity to Xylaria papulis and Sample_ID_5 had 99% identity to Leucoagaricus cepaestipes (LCU85321.1). The identification of the samples using molecular technique coincides with that of the preliminary identification of the samples using the information on the morphological characterization of mushrooms. The phylogenetic relationship among taxa showed high resolutions that are found informative on the identification and species clustering of the collected samples. Collection and identification of the macrofungi species using molecular approach as basis for identification of macrofungi provides the proper information on the identity, diversity and distribution of macrofungi in Mt. Bangkay, Cuyapo, Nueva Ecija, Philippines.

Xylaria melitensis (Xylariaceae), a new penzigioid species from the Maltese Islands

Article

Full-text available

Mar 2021

Based on detailed morphological observations of both sexual and asexual morphs in vivo, cultures in vitro and molecular phylogenetic data based on rDNA ITS and LSU sequences, we document herein a penzigioid Xylaria repeatedly collected in the Maltese islands of Gozo and Malta. Though it morphologically resembles X. sibirica by stromatal habit and ascospores in the same size range with a long sigmoid germ slit, some significant differences could be detected after comparison of this Xylaria with an isotype collection of X. sibirica. Further differences in cultural characteristics and occurrence of a distinctive asexual morph in vivo preceding the development of the sexual morph, along with a molecular phylogenetic analysis clearly showing that they are distantly related, strongly support the recognition of this penzigioid Xylaria as a distinct species with phylogenetic affinities with the X. polymorpha aggregate. We therefore introduce X. melitensis sp. nov. to accommodate it.

Seyed Abdollah Hashemi: PhD Student of mycology and plant pathology, Abstract The preliminary result of a survey conducted on Xylaria species in the North of Iran is presented. Based on morphological examination of fungal specimens collected from Guilan, Mazandaran and Golestan provinces, eight species including Xylaria arbuscula, X. cubensis, X. filiformis, X. hypoxylon, X. longipes, X. multiplex, X. pannosa, and X. polymorpha were identified. Among the identified species, X. hypoxylon, X. longipes, and X. polymorpha have been already reported from Iran and the rest are new to the Iranian mycobiota. An identification key with brief description of all species already reported from Iran is presented.

Morphology and phylogeny reveal two novel Xylaria (Xylariaceae) species from China

Article

Jun 2022

Four species of Xylaria were collected from Guizhou and Hainan provinces in China. Morphological and phylogenetic analyses (based on β-tubulin, rpb2 and α-actin genes) revealed two new species (X. sylvatica sp. nov. and X. wuzhishanensis sp. nov.) and two known species (X. atrosphaerica and X. cubensis). Xylaria sylvatica is distinguished from X. spinulosa by lacking long thorns on the stromatal surface, and larger ascospores (23–28.5 × 7–9.5 μm vs. 19–23 × 6.5–8.5 μm) with a sigmoid germ slit. Xylaria wuzhishanensis differs from X. schweinitzii by its semi-globular or irregularly globose stromata, from X. atrosphaerica by its larger ascospores (23–30.5 × 7–9 μm vs. 17–25 × 6–10 μm). Their descriptions and illustrations are provided.

Notes for genera: Ascomycota

Article

Full-text available

Oct 2017

Knowledge of the relationships and thus the classification of fungi, has developed rapidly with increasingly widespread use of molecular techniques, over the past 10–15 years, and continues to accelerate. Several genera have been found to be polyphyletic, and their generic concepts have subsequently been emended. New names have thus been introduced for species which are phylogenetically distinct from the type species of particular genera. The ending of the separate naming of morphs of the same species in 2011, has also caused changes in fungal generic names. In order to facilitate access to all important changes, it was desirable to compile these in a single document. The present article provides a list of generic names of Ascomycota (approximately 6500 accepted names published to the end of 2016), including those which are lichen-forming. Notes and summaries of the changes since the last edition of ‘Ainsworth & Bisby’s Dictionary of the Fungi’ in 2008 are provided. The notes include the number of accepted species, classification, type species (with location of the type material), culture availability, life-styles, distribution, and selected publications that have appeared since 2008. This work is intended to provide the foundation for updating the ascomycete component of the “Without prejudice list of generic names of Fungi” published in 2013, which will be developed into a list of protected generic names. This will be subjected to the XIXth International Botanical Congress in Shenzhen in July 2017 agreeing to a modification in the rules relating to protected lists, and scrutiny by procedures determined by the Nomenclature Committee for Fungi (NCF). The previously invalidly published generic names Barriopsis, Collophora (as Collophorina), Cryomyces, Dematiopleospora, Heterospora (as Heterosporicola), Lithophila, Palmomyces (as Palmaria) and Saxomyces are validated, as are two previously invalid family names, Bartaliniaceae and Wiesneriomycetaceae. Four species of Lalaria, which were invalidly published are transferred to Taphrina and validated as new combinations. Catenomycopsis Tibell & Constant. is reduced under Chaenothecopsis Vain., while Dichomera Cooke is reduced under Botryosphaeria Ces. & De Not. (Art. 59).

Jan 2015

Three species of the genus Xylaria (Xylariaceae) are presented based on collections from Guilan Province, Iran. Both morphological and molecular characteristics were used in order to identify these species. Xylaria longissima sp. nov. is described and illustrated as a new Xylaria species, and X. cf. striata and X. xylarioides are reported as new records fro Iranian mycobiota. Xylaria longissima and X. xylarioides were collected from wood of unknown dicotyledonous plants and X. cf. striata was collected from soil. Differences between these species and other closely related taxa are discussed. The result of this study indicates that sequences of internal transcribed spacer (ITS) region have sufficient resolution to distinguish between major species groups.

Study of endophytic Xylariaceae in Thailand: Diversity and taxonomy inferred from rDNA sequence analyses with saprobes forming fruit bodies in the field

Article

Full-text available

Dec 2008

A study of the diversity, taxonomy, and ecology of endophytic Xylariaceae (Ascomycota) was carried out. In this study, we obtained isolates of Xylariaceae from healthy, attached leaves and teleomorphic stromata on decayed plant materials in a permanent plot at Khao Yai National Park (Thailand). In addition, strains deposited beforehand were selected in which both endophytic strains isolated from living plant tissues and saprobic strains from fruit bodies were included. Consequently, 405 strains of Xylariaceae (273 endophytic and 132 saprobic strains, including identified strains) were studied to reveal the diversity and taxonomy of endophytes and the relationships between those endophytes and saprobic Xylariaceae in Thailand that have been recorded according to fruit-body formation on decayed plant materials. Analysis of 28S rDNA D1/D2 sequences revealed 21 xylariaceous species inhabiting tropical foliage at the site, and several species that are already known as saprobes appear to be among those isolated from living leaves. Furthermore, several clades that consisted of only endophytic strains were found, and some of these have no known matches in public DNA sequence banks.

Xylaria species associated with nests of Odontotermes formosanus in Taiwan

Article

Nov 2007

Nine species of Xylaria were collected in Taiwan from nests of Odontotermes formosanus, the only known macrotermitine termite in Taiwan. These include six newly described species, X. acuminatilongissima, X. atrodivaricata, X. brunneovinosa, X. griseosepiacea, X. intraflava and X. ochraceostroma, and three previously known species, X. cirrata, X. escharoidea and X. nigripes. We obtained cultures and ITS sequences from the nine species found in Taiwan and describe anamorphs for eight of them. Before the current study teleomorphanamorph connections in the Xylaria species associated with termite nests have been established unequivocally in X. escharoidea only. Xylaria angulosa, X. fimbriata, X. kedahae, X. micrura, X. radicans, X. reinkingii and X. tolosa also are considered and annotated because they were reported to grow on ground and likely are associated with termite nests. Epitypifications are made for X. cirrata, X. escharoidea and X. nigripes. Xylaria sanchezii is considered a nomen dubium. Photographs are presented for most of the aforementioned species. A dichotomous key to 25 Xylaria species growing on termite nests or ground also is given.

Oct 1999

One hundred and eighteen xylariaceous fungi from Taiwan were studied, including seven taxa of Biscogniauxia, one of Collodiscula, one of Creosphaeria, two of Daldinia, one of Halorosellinia, thirty-six of Hypoxylon, three of Kretzschmaria, seven of Nemania, one of Rhopalostroma, twelve of Rosellinia, three of Stilbohypoxylon, one of Whalleya, and forty-three of Xylaria. Twenty of these taxa could not be identified and may eventually be described as new. Hypoxylon ilanense, Rosellinia formosana, and Xylaria bambusicola are described as new. New combinations are proposed, as follow: Nemania memorabilis, N. minutula, Xylaria areolata, and X. glebulosa. Keys were constructed for included taxa. Cultures were obtained for ninety taxa. Many of these produced the anamorph in culture. In most cases conidiogenesis and conidiogenous cell proliferation were typical for xylariaceous fungi. Teleomorphs of several taxa of Xylaria, one of Stilbohypoxylon, and two of Nemania were induced in cultures. Comparisons were made among taxa found in Taiwan and those of some other areas where the xylariaceous mycobiota has been studied.
