Phylogenetic and chemotaxonomic resolution of the genus Annulohypoxylon(Xylariaceae)including four new species

This study deals with an extensive evaluation focusing on phylogenetic and chemotaxonomic infrageneric relationships of the genus Annulohypoxylon(Xylariaceae,Ascomycota),whose species are ubiquitously associated with seed plants as endophytes and saprotrophs in all forested areas of the world.Using evidence from phylogenetic,chemotaxonomic and morphological data,various varieties within the genus are raised to species level,leading to the new combinations for A.areolatum(:A.bovei var.microsporum),A.macrosporum(:A.leptascum var.macrosporum),and A.microdiscum(:A.moriforme var.microdiscum).Annulohypoxylon substygium nom.nov.is applied for A.stygium var.annulatumand the four new tropical and subtropical species A.massivum,A.violaceopigmentum,A.viridistratum and A.yungensis are introduced.Furthermore,A.leucadendri is excluded from the genus as its morphological characters disagree with the generic concept,the recently erected A.palmicola is synonymized with A.leptascum and A.austrobahiense has been reassigned to the genus Hypoxylon.In addition,the key taxa A.annulatum and A.truncatum have been reinvestigated and epitypes have been defined.For the first time,a dichotomous key to the genus is provided.A phylogenetic b-tubulin tree in conjunction with stromatal HPLC profiles clearly shows that Annulohypoxylon comprises two distinct lineages.The A.cohaerens/multiforme group might eventually warrant segregation into a new genus as further molecular data become available.

Towards a natural classification and backbone tree for Graphostromataceae,Hypoxylaceae,Lopadostomataceae and Xylariaceae

Species and generic recognition in the order Xylariales has been uncertain due to lack of molecular data from authentic cultures,as well as overlapping morphological characteristics.In this study,we revise the families Graphostromataceae,Hypoxylaceae,Lopadostomataceae and Xylariaceae in Xylariales.Our study is based on DNA sequence data derived from living cultures of fresh isolates,data from GenBank and morphological observation of type and worldwide herbarium specimens.We also collected new specimens from Germany,Italy and Thailand.Combined analyses of ITS,LSU,RPB2 and b-tubulin sequence data were used to reconstruct the molecular phylogeny of the above families.Generic and familiar boundaries between these families are revised and presented in an updated combined phylogenetic tree.We accept six genera in Graphostromataceae,19 genera in Hypoxylaceae,four in Lopadostomataceae and 37 genera in Xylariaceae.Five genera previously treated in Xylariaceae are placed in Amphisphaeriales genera incertae sedis and seven genera are placed in Xylariales genera incertae sedis.Two genera are placed in Sordariomycetes genera incertae sedis,while four genera are placed as Xylariomycetidae genera incertae sedis.Three genera are considered as doubtful.Barrmaelia and Cannonia,presently included in Xylariaceae are transferred to Diatrypaceae and Coniochaetales respectively,based on their morphology and phylogeny.Areolospora and Myconeesia are excluded from Xylariaceae and synonymized with Phaeosporis and Anthostomella respectively.Updated descriptions and illustrations are provided for all taxa with notes provided on each genus.Excluded and doubtful genera are listed with notes on their taxonomy and phylogeny.Taxonomic keys are provided for all revised families with morphological details for genera within the families.

Lenormandins A—G,new azaphilones from Hypoxylon lenormandii and Hypoxylon jaklitschii sp.nov.,recognised by chemotaxonomic data

Seven new azaphilone pigments named lenormandins A–G were isolated from stromata(fruiting bodies)of the xylariaceous fungus,Hypoxylon lenormandii using preparative High Performance Liquid Chromatography(HPLC)and their structures were elucidated by NMR spectroscopy,high resolution mass spectrometry and other spectral methods.Their occurrence in herbarium specimens(including various type materials collected in the 19th and early 20th century)and several fresh collections was studied by analytical HPLC with diode array and mass spectrometric detection(HPLC-DAD/MS),revealing that this group of pigments is specific for Hypoxylon lenormandii from various geographic regions and otherwise only occurs in closely related taxa,i.e.H.sublenormandii and an undescribed fungus from Sri Lanka,for which we propose the name H.jaklitschii.The status of the new species was established by using molecular phylogenetic data based on ITS and partial beta-tubulin sequences,and by detailed morphological studies.
