Abstract

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.

Abstract: Some interesting records of plant parasitic microfungi of the Erysiphaceae, Peronosporomycetes, Pucciniomycotina, Ustilaginomycotina, Chytridiomycota and other Ascomycota from Germany, Austria and Switzerland are reported. Podosphaera pruni-lusitanicae on cultivated Prunus lusitanica is documented in Germany for the first time. Podosphaera cerasi on Prunus cerasus was confirmed to occur in Germany based on molecular genetic data. Uromyces proëminens on Euphorbia prostrata is new for Germany. Investigations have shown that the species has been present in Germany since 2011. A find from Switzerland on the host mentioned above is a new fungus-host combination for the fungus, which is still rare in Switzerland. Uromyces sparsus was rediscovered after 50 years in Germany on Spergularia marina. Literature references to Spergularia rubra as host for this fungus are incorrect. Thecaphora lathyri on Lathyrus pratensis, which has not been reported in Germany since 1963, was found again in 2021 and has since been detected in three other federal states. Urocystis ornithogali on Ornithogalum umbellatum agg. was rediscovered in Germany after around 140 years. Exobasidium schinzianum was found on Saxifraga rotundifolia in Austria, probably the only recent record for a long time. As new hosts for Germany Allium x proliferum for Uromyces ambiguus, Phaseolus coccineus for Podosphaera xanthii and Symphytum caucasicum for Golovinomyces asperifoliorum were identified. The finds of Anthemis ruthenica with Golovinomyces macrocarpus and Leontodon incanus with Ramularia inaequalis are probably matrices novae. In addition other interesting records of phytopathogenic microfungi are listed at the end of the publication, e.g. new records for federal states of Germany, Austria and Switzerland. Keywords: Podosphaera spp., Prunus spp., Thecaphora lathyri, Urocystis ornithogali, Uromyces proëminens, Uromyces sparsus, Germany, Austria, Switzerland, matrix nova, new records, sequences

Some interesting records of plant parasitic microfungi of the Erysiphaceae, Peronosporomycetes, Pucciniomycotina, Ustilaginomycotina and Plasmodiophoridae are reported. Erysiphe australiana is documented in Germany for the first time. It was found on cultivatedLagerstroemia indica. Chondrilla juncea, Crepis pulchra, C. setosa and Leontodon saxatilis are new host species for Neoerysiphe nevoi in Central Europe. All earlier records are from Lapsana communis in Germany. The first one dates from 1988. New host species in Germany are Hypericum inodorum for Melampsora hypericorum, Knautia arvensis for Podosphaera dipsacacearum and Cucurbita moschata for P. xanthii. For the latter Dahlia x hortensis is possibly a matrix nova. Viola biflora is a new host species for Peronospora violae in Austria and Plasmoverna pygmaea for Clematis alpina. Recent records of Puccinia stachydis in Germany and a distribution map are provided. A finding of Podosphaera physocarpi on Physocarpus opulifolius is the second record of this fungus in Germany. Sorosphaerula veronicae on Veronica arvensis is portrayed. It is an overlooked species. In addition other interesting records are listed at the end of the publication, e.g. new records for federal states of Germany and Austria.

Abstract: Some interesting records of plant parasitic microfungi of the Erysiphaceae, Pero-nosporomycetes, Pucciniomycotina, Ustilaginomycotina and anamorphic Ascomycetes collected in Germany and Austria are reported. A record of Entyloma on Scorzonera hispanica belongs to a new species that has not yet been described. The plant species was not known as a host for the genus Entyloma before. The North American Microbotryum alsines was found for the first time in Europe on Stellaria media. A record of Erysiphe syringae on Fraxinus pennsylvanica is the first record of this powdery mildew on the genus Fraxinus in Europe. The host species is a matrix nova for this fungus. Puccinia scirpi was rediscovered in Germany after 80 years on Nymphoi-des peltata. Exobasidium schinzianum on Saxifraga rotundifolia, Peronospora ruegeriae on Onobry-chis viciifolia and Urocystis bolivarii on Lolium perenne are reported as new for Germany. Three recorded host species are matrices novae: Cornus mas for Erysiphe pulchra, Eutrema japonicum for Erysiphe cruciferarum and Origanum vulgare for Peronospora stigmaticola. In addition other interesting records are listed, including formerly unknown host species in Germany, e. g.

Some interesting records of plant parasitic microfungi of the Erysiphales and Ustilaginomycotina are reported from Germany. The first record of Podosphaera amelanchieris for Germany is predated to 1990, based on a review of two specimens from REG. Furthermore it was detected that Phyllactinia mali does not occur on Amelanchier lamarckii in Germany and Amelanchier ovalis is no host of Podosphaera amelanchieris in Germany. A recent collection of the rare smut fungus Ustilago hordei is presented, collected on Hordeum vulgare. Furthermore the rare smut fungus Urocystis violae is portrayed added with recent finds on Viola odorata. Regarding the hosts of different Entyloma species on Ranunculus spp. we inform about new species and concepts within these smut species. At the end of the paper some formerly unknown fungi and host species for different plant parasitic microfungi for the federal states of Germany and Austria are listed. Included is the first record of Phyllactinia roboris in Germany after 120 years on the new host species Fagus sylvatica (matrix nova). Zusammenfassung Vorgestellt werden interessante Funde von Echten Mehltaupilzen (Erysiphales) und Brandpilzen (Ustilaginomycotina) aus Deutschland. Der Erstnachweis des Neomy-zeten Podosphaera amelanchieris wurde nach Prüfung zweier Belege aus REG auf 1990 vordatiert. Weiterhin wurde im Rahmen dieser Untersuchungen festgestellt, dass Phyllactinia mali nicht auf Amelanchier lamarckii vorkommt und dass Amelanchier ova-lis als Wirt für Podosphaera amelanchieris zu streichen ist. Ein aktueller Nachweis von Ustilago hordei, gesammelt auf Hordeum vulgare, wird vorgestellt. Weiterhin werden der seltene Brandpilz Urocystis violae und seine aktuellen Nachweise in Deutsch-land präsentiert. Bezüglich der Wirte von Entyloma-Arten auf Ranunculus spp.

A new allotetraploid species in the Stellaria media group, S. ruderalis M. Lepší, P. Lepší, Z. Kaplan & P. Koutecký, which is possibly of hybridogenous origin between S. pallida and S. neglecta, is distinguished and described based on a biosystematic revision of the S. media group. A suite of bio-systematic techniques, including molecular (internal transcribed spacer sequencing), karyological (chromosome counting, flow cytometry), multivariate morphometrics and phenological observations, was used to assess the variation in this species group and determine the taxonomic status of the species. All the methods employed produced similar results and supported the delimitation of four species within the Stellaria media group in central Europe: Stellaria ruderalis (2n = 4x = 44), S. pallida (2n = 2x = 22), S. neglecta (2n = 2x = 22) and S. media s. str. (2n = 4x = 40). Stellaria ruderalis is a winter annual growing mainly in disturbed ruderal open or semi-open communities. This species' broad ecological amplitude allows it to commonly co-occur with its three related species. It is probably a widespread species in southern and central Europe. It is currently spreading in the northern part of central Europe. Photographs of the type specimen and individuals of the new species in situ are presented. Scanning electron micrographs of seeds, microphotographs of seeds and mitotic chromosome spreads and a key for the identification of all four species are provided.

Some interesting records of plant parasitic microfungi of the Ustilaginomycotina, Pucciniomycotina and Oomycota are reported from Austria, Germany and Italy. Antherospora vindobonensis on Scilla vindobonensis and Puccinia smyrnii on Smyrnium perfoliatum are reported from Germany for the first time. Novotelnova scorzonerae on Scorzonera hispanica was rediscovered after more than 100 years in Germany. Up to now only five collections of this fungus exist worldwide. Altogether four samples of Schizonella elynae on Kobresia myosuroides were collected in Italy (2x), Austria and Germany representing first records for these countries. They ensure that this northern European smut fungus also occurs in the Alps. Regarding the hosts of Ustilago striiformis agg. we inform about some corrections of previous reports in this series. At the end of the paper some formerly unknown fungi and host species for different plant parasitic microfungi for the federal states of Germany are listed. Zusammenfassung: Vorgestellt werden interessante Funde von Brandpilzen (Ustilaginomycotina), Rostpilzen (Pucciniomycotina) und Falschen Mehltauen (Oomycota) aus Deutschland, Österreich und Italien. Antherospora vindobonensis auf Scilla vindobonensis wurde erstmals in Deutschland nachgewiesen. Außerdem wird über die ersten Funde von Puccinia smyrnii auf Smyrnium perfoliatum in Deutschland berichtet. Auf Scorzonera hispanica wurde Novotelnova scorzonerae nach über 100 Jahren wieder in Deutschland nachgewiesen. Mit den beiden aktuellen Funden existieren jetzt weltweit erst fünf Aufsammlungen dieses Pilzes. Insgesamt vier Funde von Schizonella elynae auf Kobresia myosuroides aus Italien (2x), Österreich und Deutschland sind die ersten Funde aus diesen Ländern. Sie dokumentieren, dass der aus Nordeuropa bekannte Pilz auch in den Alpen vorkommt. Bezüglich der Wirte von Arten aus der Ustilago striiformis-Gruppe werden einige Korrekturen zu früheren Angaben in dieser Reihe vorgenommen. Erfolgreiche Nachsuchen von bereits in dieser Reihe vorgestellten Arten sowie einige weitere Neufunde von in einzelnen Bundesländern Deutschlands bisher nicht nachgewiesenen Pilzen oder Pilz-Wirt-Kombinationen sind tabellarisch am Ende des Artikels zusammengefasst.

Some interesting records of plant parasitic microfungi of the Ustilaginomycotina and Pucciniomycotina are reported from Austria and Germany. Puccinia bellidiastri on Bellidiastrum michelii and Tilletia anthoxanthi on Anthoxanthum nipponicum are presented with the first records from Germany. Melampsora pulcherrima on Mercurialis annua and Entyloma cichorii on Cichorium intybus were found for the first time in the German-speaking area of Central Europe. Furthermore Melampsora liniperda is presented based on collections from Germany from a matrix nova: Linum leonii. Recent collections and the distribution of Melampsora galanthi-fragilis in Germany and Austria are presented and two new host plants (Galanthus elwesii and G. plicatus subsp. byzantinus) for Germany are listed. At the end of the paper some formerly unknown fungi and host species for different phytoparasitic microfungi for the federal states of Germany and Austria are summarised.

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 of G. cynoglossi s. lat. Phylogenetic analysis of rDNA ITS sequences retrieved from Asian, European and North American specimens revealed that G. cynoglossi s. lat. collections from different hosts involved several species in five clearly separated lineages. Clade I consists primarily of Golovinomyces cynoglossi s. str. on Cynoglossum. Clade III consists of Golovinomyces sequences retrieved from the host genera Symphytum and Pulmonaria. The taxa within clade III are now assigned to G. asperifoliorum comb. nov. Clade V encompasses G. cynoglossi s. lat. on the host genera Bothriospermum, Buglossoides, Echium, Myosotis, and Trigonotis. The taxa within clade V are now assigned to G. asperifolii comb. nov. The species concerned in this study were lecto-and epitypified to stabilize their nomenclature. ARTICLE HISTORY

Plant pathogenic smut fungi in the broader sense can be divided into the Ustilaginomycetes, which cause classical smut symptoms with masses of blackish spores being produced in a variety of angiosperms, and the Exobasidiomycetes, which are often less conspicuous, as many do not shed large amounts of blackish spores. The leaf-spot causing members of the genus Entyloma (Entylomatales, Exobasidiomycetes) belong to the latter group. Currently, 172 species that all infect eudicots are included in the genus. Vánky (2012) recognised five Entyloma species on species of Ranunculus s.lat. Two have been reported only from Ficaria verna s.lat., while three, E. microsporum, E. ranunculi-repentis, E. verruculosum, have been reported to have a broad host range, encompassing 30, 26, and 5 species of Ranunculus, respectively. This broad host range is in contrast to the generally high host specificity assumed for species of Entyloma, indicating that they may represent complexes of specialised species. The aim of this study was to investigate Entyloma on Ranunculus s.lat. using multigene phylogenies and morphological comparisons. Phylogenetic analyses on the basis of up to four loci (ITS, atp2, ssc1, and map) showed a clustering of Entyloma specimens according to host species. For some of these Entyloma lineages, names not currently in use were available and reinstated. In addition, Entyloma microsporum s.str. is neotypified. Six novel species are described in this study, namely, Entyloma jolantae on Ranunculus oreophilus, E. klenkei on R. marginatus, E. kochmanii on R. lanuginosus, E. piepenbringiae on R. polyanthemos subsp. nemorosus (type host) and R. repens, E. savchenkoi on R. paludosus, and E. thielii on R. montanus. For all species diagnostic bases and morphological characteristics are provided. The results in this study once more highlight the importance of detailed re-investigation of broad host-range pathogens of otherwise specialised plant pathogen groups.

In the preparation of this descriptive manual of the rust fungi of the grasses of the world the principal goal was to produce a system by which these important pathogens might be recognized on the basis of their morophology, without dependence on the identity of the host plant. This is an Utopian goal and, being Utopian, has doubtless not been attained. But it is better to have tried and partially failed than not to have tried at all. The first attempt to revise the classification on a new basis utilized the rust fungi of the tribe Andropogoneae. A "Group System" was initiated (Uredineana 4:5-89. 1953) based on the uredinial stage. The attempt was satisfactory at the time, but was not adaptable when all grass rust fungi were considered. Consequently, an expanded system was employed when I attempted a summarization of all grass rust fungi. The expanded scheme (Plant Disease Reporter Supplement 237:1-52. 1956) of 9 Groups proved to be a most helpful organizational system and is used here (see explanations, p. Xi) in Puccinia, Uromyces, and Uredo. The system is useful and does aggregate generally similar species, rather than segregating them as in a host-based arrangement. The characters used, i.e. presence or absence of paraphyses, arrangement of germ pores, and echinulate or verrucose spore surface, are subject to minimal intergradations.
