The name Golovinomyces cynoglossi s. lat. is traditionally applied to a complex of morphologically similar powdery mildews on hosts of the plant family Boraginaceae. The current species-level taxonomy within this complex is ambiguous due to the lack of phylogenetic examinations. The present study applied phylogenetic methods to clarify the taxonomy...

The powdery mildew species Erysiphe lonicericola, collected in China on Lonicera rupicola, is described on the basis of its morphological characteristics and analyses of the internal transcribed spacer (ITS) region of the ribosomal DNA, which suggested the involvement of a new species. Light and scanning electron microscopy observations indicated that this species is morphologically clearly distinguished from Erysiphe chifengensis and E. ehrenbergii, two similar species on other hosts of the Caprifoliaceae. It could be demonstrated that the L. rupicola powdery mildew is genetically different from all other Erysiphe species, but the phylogenetic affinity of the new species could not be clarified. The bootstrap support values of the corresponding deeper branches are too low.

Powdery mildews are a monophyletic group of obligate plant pathogenic fungi in the family Erysiphaceae. Powdery mildews are economically important in that they cause damage to many agriculturally significant crops and plants in ecologically important habitats. In this contribution, we introduce a new series of publications focusing on the phylogeny and taxonomy of this group, with an emphasis on specimens collected from North America. The first part of the series focuses on the genus Golovinomyces and includes a section detailing the powdery mildew species concept. We conducted analyses of Golovinomyces spp. with available rDNA sequence data from GenBank and supplemented the data set with rDNA (ITS, 28S, IGS) as well as protein-coding (GAPDH) data from 94 North American collections. Many of the species evaluated are included in phylogenetic and morphological analyses for the first time, including the American species G. americanus, G. brunneopunctatus, G. californicus, G. greeneanus, G. hydrophyllacearum, and G. sparsus. A special emphasis was placed on acquiring ex-type or ex-epitype sequences or presenting reference sequences for phylogenetic-taxonomic purposes. Three new species, G. eurybiarum, G. galiorum, and G. malvacearum, are described, and the new combinations G. fuegianus, G. mutisiae, and G. reginae are introduced. Ex-holotype sequences of Erysiphe sparsa (≡ G. sparsus) reveal that it should be reduced to synonymy with G. ambrosiae, and ex-epitype sequences of G. valerianae reveal that it should be reduced to synonymy with G. orontii. Multiple epitypes are designated with ex-epitype sequences.
... The obtained sequences, including complete ITS and partial 28S rDNA, were deposited in GenBank. The combined dataset of ITS and 28S rDNA sequences was aligned with closely related sequences of the genus Golovinomyces (Table S1) (Kiss et al., 2001;Matsuda and Takamatsu, 2003;Takamatsu et al., 2006;2008;2009;2013;Park et al., 2010;Scholler et al., 2016;Bradshaw et al., 2017;Braun et al., 2018;Meeboon et al., 2018;Ellingham et al., 2019;Qiu et al., 2020). Golovinomyces inulae was selected as the outgroup taxon (Takamatsu et al., 2013). ...

The Golovinomyces cichoracearum complex is morphologically highly variable and causes powdery mildew on a wide range of Compositae, including Hieracium spp. and Lapsana communis. A comprehensive phylogenetic analysis of Golovinomyces, published in 2013, revealed that G. cichoracearum s. str. was confined to Scorzonera and Tragopogon spp. as hosts (Compositae, tribe Lactuceae, subtribe Scorzonerinae). To clarify the phylogeny and taxonomy of Golovinomyces on Hieracium spp. (Compositae, tribe Lactuceae, subtribe Hieraciinae), which is common in Asia and Europe, morphology and phylogenetic analyses of ITS + 28S rDNA sequences were conducted for 57 powdery mildew specimens of Hieracium spp. and Lapsana communis. Golovinomyces on Hieracium spp. in Asia and Europe, previously referred to as G. cichoracearum, is a previously undescribed, cryptic species, which is described here as Golovinomyces hieraciorum sp. nov.. Since a sequence retrieved from a powdery mildew on Lapsana communis in Switzerland clustered in sister position to the G. hieraciorum clade, numerous German specimens identified as G. cichoracearum were included in the present examinations. All the re-examined collections of “G. cichoracearum” on L. communis were misidentified, and were shown to belong to Neoërysiphe nevoi or Podosphaera ergerontis-canadensis.

... Developing the specific molecular-phylogenetic tech-niques have also essentially contributed to the precise identification, construction of phylogeny and study of evolution of this group of fungi (Hirata & Takamatsu 1996, Takamatsu & Kano 2001, Bradshaw & Tobin 2020. The modern investigations have defined taxonomic status of many cryptic species and complex constitutes of powdery mildews (Scholler et al. 2016;Braun et al. 2018Braun et al. , 2019Meeboon et al. 2020;Qiu et al. 2020a, b) and comprehensive information about pathogenic features of different species has been obtained. Currently, powdery mildews are allocated within the order Helotiales according to the results of recent molecularphylogenetic studies (Johnston et al. 2019). ...

Powdery mildew diseases on crops and ornamental plants are common and cause significant economic losses, by reducing the yield and quality of crops and downgrading the value of ornamentals. In surveys published annually in the Canadian Plant Disease Survey, powdery mildews were reported frequently. In recent years, the taxonomy of powdery mildew fungi has changed tremendously as the result of the increased application of molecular phylogenetic analyses. Several generic concepts have been re-adjusted. Many traditionally considered species turned out to be a complex of several phylogenetic species. In order to facilitate effective communication in the scientific community, it is important to apply the current correct names for field identifications. In this document, we summarize the powdery mildew fungi reported in the Canadian Plant Disease Survey from 2000 to 2019, address the taxonomic and nomenclatural issues associated with the listed species, and tentatively suggest correct names based on host plants wherever possible. Nevertheless, a reliable identification of the powdery mildew must depend on DNA sequence analyses and morphological examinations.

Abstract: Some interesting records of plant parasitic microfungi of the Oomycota, Synchytrium (Chytridiomycota), Erysiphaceae, Pucciniomycotina and Ustilaginomycotina collected in Germany and Austria are reported. Several records of the rust fungus Puccinia cynodontis on the aeciaand telia-hosts including the first record on Plantago lanceolata in Germany are presented. The first records of Puccinia scillae-rubrae on Scilla bifolia in Germany since 50 years are portrayed, and furthermore the first record of this rust fungus since 20 years for Austria on the matrix nova Scilla vindobonensis. For Tilletia separata the first collections for Germany since 50 years are presented. A recent distribution map of Melampsora pulcherrima for Germany and the first record of this rust fungus in Austria is given. This paper concludes with a list of some formerly unknown fungi and host species for different plant parasitic microfungi for the federal states of Germany and Austria. The first recent record of Erysiphe geraniacearum on Geranium pratense since more than 100 years in Germany is listed here. Urocystis phlei-alpini on Phleum pratense is reported for the first time in Germany and Caeoma scillae on Scilla bifolia the first time for Austria. Also some matrices novae for several plant parasitic microfungi are listed.

The phylogeny and taxonomy of several powdery mildews (Erysiphaceae) have been examined. Sequences of the rDNA ITS region retrieved from several collections of Erysiphe spp. belonging to the E. aquilegiae complex (cluster) and collected on new hosts are listed and discussed, including a critical assessment of the phylogenetic-taxonomic interpretation of this complex. Based on results of sequence analyses, E. tortilis proved to pertain to this complex as well. This species is epitypified, which is supplemented with an ex-epitype reference sequence. The phylogeny and taxonomy of the powdery mildew on Manihot esculenta (cassava, manioc), which is widespread and common wherever this tuber crop is cultivated, has been examined. Morphological re-examinations and phylogenetic analyses of collections from Argentina and Brazil revealed that this powdery mildew belongs to the genus Erysiphe, phylogenetically included in the E. trifoliorum complex. The new combination Erysiphe manihoticola is introduced for this powdery mildew. Based on the re-examination of type material, it has become clear that the name Oidium manihotis, which was used in the past for this powdery mildew, is not conspecific with E. manihoticola and most likely not congeneric with Erysiphe. On the basis of sequences retrieved from type material of Erysiphe baptisiae and a North American collection on Baptisia, we reveal that E. baptisiae has to be reduced to synonymy with E. guarinonii. Erysiphe euonymicola on Euonymus fortunei is recorded from North America for the first time. The identity of Golovinomyces on Cynara and Echinops in North America is discussed. Type material of Golovinomyces echinopis has been sequenced, and G. montagnei is epitypified with a collection from Germany, which is supplemented by ex-epitype sequence data. Based on morphological analyses and a comparison of sequence data with ex-holotype sequences, North American powdery mildew collections on Echinops could be confirmed to belong to G. echinopis. However, a North American powdery mildew collection on Cynara cardunculus turned out to be close to G. depressus and not, as expected, to G. montagnei. Golovinomyces verbenae, described from North America, is epitypified with ex-epitype sequence data, and G. glandulariae, recently described from Australia, is reduced to synonymy with G. verbenae. The phylogenetic positions of Podosphaera physocarpi and P. spiraeae-douglasii have been revealed on the basis of collections from North America and Germany (the first record for Germany and the second for Europe of P. physocarpi), including the first descriptions, pictures and illustrations of the asexual morphs for both of these species. Furthermore, Podosphaera prunicola is epitypified.
