A case for re-inventory of Australia’s plant pathogens Naturalis
Hyde, K.D.; Chomnunti, P.; Crous, P.W.; Groenewald, J.Z.; Damm, U.; Ko Ko, T.W.; Shivas, R.G.; Summerell, B.A.; Tan, Y.P..
Several filamentous oomycete species of the genus Halophytophthora have recently been described from marine environments, mostly from subtropical and tropical ecosystems. During a survey of oomycetes from leaf litter of Spartina alterniflora in salt marshes of southeastern Georgia, isolates of four taxa were recovered that bore similarity to some members of Halophytophthora but were highly divergent from isolates of Halophytophthora s.str. based on a combined sequence analysis of two nuclear loci. In phylogenetic analyses, these isolates were placed basal to a monophyletic group comprised of Pythium of the Pythiaceae and the Peronosporaceae. Sequence and morphology of these taxa diverged from the type species Halophytophthora vesicula, which was placed...

A multi-gene phylogeny of Lactifluus (Basidiomycota, Russulales) translated into a new infrageneric classification of the genus Naturalis
Crop, E. de; Nuytinck, J.; Putte, K. van de; Wisitrassameewong, K.; Hackel, J.; Stubbe, D.; Hyde, K.D.; Roy, M.; Halling, R.E.; Moreau, P.-A.; Eberhardt, U.; Verbeken, A..
Infrageneric relations of the genetically diverse milkcap genus Lactifluus (Russulales, Basidiomycota) are poorly known. Currently used classification systems still largely reflect the traditional, mainly morphological, characters used for infrageneric delimitations of milkcaps. Increased sampling, combined with small-scale molecular studies, show that this genus is underexplored and in need of revision. For this study, we assembled an extensive dataset of the genus Lactifluus, comprising 80 % of all known species and 30 % of the type collections. To unravel the infrageneric relationships within this genus, we combined a multi-gene molecular phylogeny, based on nuclear ITS, LSU, RPB2 and RPB1, with a morphological study, focussing on five important...

A new species of bird’s nest fungi: characterisation of Cyathus subglobisporus sp. nov. based on morphological and molecular data Naturalis
Zhao, R.-L.; Desjardin, D.E.; Soytong, K.; Hyde, K.D..
Recent collections of bird’s nest fungi (i.e. Crucibulum, Cyathus, Mycocalia, Nidula, and Nidularia species) in northern Thailand resulted in the discovery of a new species of Cyathus, herein described as C. subglobisporus. This species is distinct by a combination of ivory-coloured fruiting bodies covered with shaggy hairs, plications on the inner surface of the peridium and subglobose basidiospores. Phylogenetic analyses based on ITS and LSU ribosomal DNA sequences using neighbour-joining, maximum likelihood and weighted maximum parsimony support Cyathus subglobisporus as a distinct species and sister to a clade containing C. annulatus, C. renweii and C. stercoreus in the Striatum group.

Microcyclospora and Microcyclosporella: novel genera accommodating epiphytic fungi causing sooty blotch on apple Naturalis
Frank, J.; Crous, P.W.; Groenewald, J.Z.; Oertel, B.; Hyde, K.D.; Phengsintham, P.; Schroers, H.-J..
Recent studies have found a wide range of ascomycetes to be associated with sooty blotch and flyspeck (SBFS) blemishes on the surfaces of pomaceous fruits, specifically apples. Based on collections of such fungi from apple orchards in Germany and Slovenia we introduce two novel genera according to analyses of morphological characters and nuclear ribosomal DNA sequences (large subunit and internal transcribed spacer regions). Microcyclosporella is represented by a single species, M. mali, and is presently known from Germany and Slovenia. Microcyclosporella is Pseudocercosporella-like in morphology, but genetically and morphologically distinct from Pseudocercosporella s.str., for which an epitype is designated based on a fresh collection of P. bakeri from...

Morphological and molecular characterisation of a new anamorphic genus Cheirosporium, from freshwater in China Naturalis
Cai, L.; Guo, X.Y.; Hyde, K.D..
Cheirosporium gen. nov. is characterised by the production of sporodochial conidiomata, semi-macronematous to macronematous conidiophores that possess several distinct sterile branches, and cheiroid, smooth-walled conidia with rhexolytic secession. The 28S rDNA and ITS rDNA operon of this taxon were amplified and sequenced. A BLAST search revealed low homology between Cheirosporium triseriale and existing sequences in public databases, supporting the hypothesis that the species is new to science. Phylogenetic analysis showed that C. triseriale groups with Dictyosporium and allied species, and nests within the Pleosporales (Dothideomycetes, Ascomycota). heirosporium is morphologically distinct from the cheirosporous genera Cheiromyces, Cheiromycina,...

Phylogenetic and morphological assessment of two new species of Amniculicola and their allies (Pleosporales) Naturalis
Zhang, Y.; Fournier, J.; Crous, P.W.; Pointing, S.B.; Hyde, K.D..
Two new species of Amniculicola, A. immersa sp. nov. and A. parva sp. nov. from submerged wood in a freshwater environment in Denmark and France are respectively described and illustrated. In addition, partial 28S rDNA sequence data is analysed to investigate their phylogenetic relationships with other pleosporalean taxa. All presently known Amniculicola species, A. immersa, A. lignicola and A. parva, form a robust clade together with the anamorphic species Anguillospora longissima, Spirosphaera cupreorufescens and Repetophragma ontariense. These six species, which are all from freshwater and mostly from Europe, constitute a well-supported group containing Pleospora rubicunda and Massariosphaeria typhicola. This putative monophyletic assemblage may...

Species limits in Diaporthe: molecular re-assessment of D. citri, D. cytosporella, D. foeniculina and D. rudis Naturalis
Udayanga, D.; Castlebury, L.A.; Rossman, A.Y.; Hyde, K.D..
Species of Diaporthe are important plant pathogens of a wide range of hosts worldwide. In the present study the species causing melanose and stem end rot diseases of Citrus spp. are revised. Three species of Diaporthe occurring on Citrus are characterised, including D. citri, D. cytosporella and D. foeniculina. Morphology and phylogenetic analyses of the complete nuclear ribosomal internal transcribed spacer regions and partial sequences of actin, beta-tubulin, calmodulin and translation elongation factor 1-α were used to resolve species on Citrus and related Diaporthe species. Diaporthe citri occurs on Citrus throughout the Citrus-growing regions of the world. Diaporthe cytosporella is found on Citrus in Europe and California (USA). Diaporthe foeniculina,...

Species of Mycosphaerella and related anamorphs on Eucalyptus leaves from Thailand Naturalis
Crous, R. Cheewangkoon: P.W.; Hyde, K.D.; Groenewald, J.Z.; To-anan, C..
Species of Mycosphaerella and their related anamorphs represent potentially serious foliar pathogens of Eucalyptus. The fungi treated in the present study were isolated from symptomatic Eucalyptus leaves collected in Thailand during June –October 2007. Species were initially identified based on morphological and cultural characteristics. Identifications were confirmed using comparisons of DNA sequence data of the internal transcribed spacers (ITS1, 5.8S nrDNA, ITS2) and the 28S nrDNA (LSU) regions. To help distinguish species of Pseudocercospora, the dataset was expanded by generating partial sequences of the translation elongation factor 1-α and actin genes. By integrating the morphological and molecular datasets, five new taxa were distinguished, namely...

Study in Agaricus subgenus Minores and allied clades reveals a new American subgenus and contrasting phylogenetic patterns in Europe and Greater Mekong Subregion Naturalis
Chen, J.; Callac, P.; Parra, L.A.; Karunarathna, S.C.; He, M.-Q.; Moinard, M.; De Kesel, A.; Raspé, O.; Wisitrassameewong, K.; Hyde, K.D.; Zhao, R.-L..
Within Agaricus subg. Minores, A. sect. Minores remains a little-studied section due generally to its delicate sporocarps often lacking taxonomically relevant morphological characters. To reconstruct the section, using the recent taxonomic system based on divergence times, and to evaluate the species diversity of A. sect. Minores in the Greater Mekong Subregion, 165 specimens were incorporated in phylogenetic analyses. A dated tree based on nuclear ITS, LSU and tef1-α sequence data allowed us to better circumscribe A. subg. Minores and to propose a new subgenus, A. subg. Minoriopsis, which is only known from tropical and subtropical regions of the Americas. A larger tree based on ITS sequences indicated that, with 81 phylogenetic species, the reconstructed...
