    Multiple gene genealogies and phenotypic characters differentiate several novel species of Mycosphaerella and related anamorphs\non banana (2008)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 20 no. 1, pp. 19-37
    Details
    Publication Date: 2024-01-12
    Description: Three species of Mycosphaerella, namely M. eumusae, M. fijiensis, and M. musicola are involved in the Sigatoka disease complex of bananas. Besides these three primary pathogens, several additional species of Mycosphaerella or their anamorphs have been described from Musa. However, very little is known about these taxa, and for the majority of these species no culture or DNA is available for study. In the present study, we collected a global set of Mycosphaerella strains from banana, and compared them by means of morphology and a multi-gene nucleotide sequence data set. The phylogeny inferred from the ITS region and the combined data set containing partial gene sequences of the actin gene, the small subunit mitochondrial ribosomal DNA and the histone H3 gene revealed a rich diversity of Mycosphaerella species on Musa. Integration of morphological and molecular data sets confirmed more than 20 species of Mycosphaerella (incl. anamorphs) to occur on banana. This study reconfirmed the previously described presence of Cercospora apii, M. citri and M. thailandica, and also identified Mycosphaerella communis, M. lateralis and Passalora loranthi on this host. Moreover, eight new species identified from Musa are described, namely Dissoconium musae, Mycosphaerella mozambica, Pseudocercospora assamensis, P. indonesiana, P. longispora, Stenella musae, S. musicola, and S. queenslandica.

    Re-evaluation of Phytophthora citricola isolates from multiple woody hosts in Europe and North America reveals a new species, Phytophthora plurivora sp. nov (2009)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 22 no. 1, pp. 95-110
    Details
    Publication Date: 2024-01-12
    Description: During large-scale surveys for soilborne Phytophthora species in forests and semi-natural stands and nurseries in Europe during the last decade, homothallic Phytophthora isolates with paragynous antheridia, semipapillate persistent sporangia and a growth optimum around 25 \xc2\xb0C which did not form catenulate hyphal swellings, were recovered from 39 host species in 16 families. Based on their morphological and physiological characters and the similarity of their ITS DNA sequences with P. citricola as designated on GenBank, these isolates were routinely identified as P. citricola. In this study DNA sequence data from the internal transcribed spacer regions (ITS1 and ITS2) and 5.8S gene of the rRNA operon, the mitochondrial cox1 and \xce\xb2-tubulin genes were used in combination with morphological and physiological characteristics to characterise these isolates and compare them to the ex-type and the authentic type isolates of P. citricola, and two other taxa of the P. citricola complex, P. citricola I and the recently described P. multivora. Due to their unique combination of morphological, physiological and molecular characters these semipapillate homothallic isolates are described here as a new species, P. plurivora sp. nov.

    Native and non-native species of hard substrata in the Dutch Wadden Sea (2010)
    In:  Nederlandse Faunistische Mededelingen vol. 33, pp. 21-75
    Details
    Publication Date: 2024-01-12
    Description: Bij een inventarisatie van hard substraat in 83 locaties in de Nederlandse Waddenzee, in zoutgehaltes van 10-32 ppt, werden in juli/augustus 2009 in totaal 129 soorten planten en dieren waargenomen. Van deze soorten hadden er 29 een uitheemse of onbekende oorsprong. In aanvulling hierop werd een inventarisatie gemaakt van nog ongepubliceerde waarnemingen in de Waddenzee. Elf soorten en \xc3\xa9\xc3\xa9n ondersoort waren nog niet eerder geregistreerd in de Nederlandse Waddenzee. E\xc3\xa9n alg, Ceramiaceae sp., met onbekende oorsprong, is vermoedelijk een nieuwe soort voor Europa. E\xc3\xa9n zakpijpsoort, Molgula socialis, is nieuw voor Nederland. Deze soort is waarschijnlijk algemeen verspreid in Nederland en is mogelijk zelf inheems. In het\nverleden was hij vermoedelijk vaak foutief gedetermineerd als de invasieve Amerikaanse zakpijp Molgula manhattensis, die van Molgula socialis alleen onderscheiden kan worden aan de hand van anatomische details. De 11 nieuwe soorten (en \xc3\xa9\xc3\xa9n nieuwe ondersoort) verhogen het totaal aantal van in de Waddenzee geregistreerde soorten van uitheemse of onbekende afkomst tot 64. Het relatief hoge aantal nieuwe soorten voor de Waddenzee dat binnen drie weken veldwerk gevonden kon worden, lijkt gerelateerd te zijn aan het feit dat het biodiversiteitsonderzoek in de Waddenzee zich in het verleden nooit specifiek heeft gericht op hard substraat, zoals drijvende steigers in jachthavens. Verder valt niet uit te sluiten dat verschillende soorten zich pas recentelijk in de Nederlandse Waddenzee hebben gevestigd.

    Phytophthora multivora sp. nov., a new species recovered from declining Eucalyptus, Banksia, Agonis and other plant species in Western Australia (2009)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 22 no. 1, pp. 1-13
    Details
    Publication Date: 2024-01-12
    Description: A new Phytophthora species, isolated from rhizosphere soil of declining or dead trees of Eucalyptus gomphocephala, E. marginata, Agonis flexuosa, and another 13 plant species, and from fine roots of E. marginata and collar lesions of Banksia attenuata in Western Australia, is described as Phytophthora multivora sp. nov. It is homothallic and produces semipapillate sporangia, smooth-walled oogonia containing thick-walled oospores, and paragynous antheridia. Although morphologically similar to P. citricola, phylogenetic analyses of the ITS and cox1 gene regions demonstrate that P. multivora is unique. Phytophthora multivora is pathogenic to bark and cambium of E. gomphocephala and E. marginata and is believed to be involved in the decline syndrome of both eucalypt species within the tuart woodland in south-west Western Australia.

    Multiple new Phytophthora species from ITS Clade 6 associated with natural ecosystems in Australia: evolutionary and ecological implications (2011)
    In:  Persoonia - Molecular Phylogeny and Evolution of Fungi vol. 26 no. 1, pp. 13-39
    Details
    Publication Date: 2024-01-12
    Description: During surveys of dying vegetation in natural ecosystems and associated waterways in Australia many new taxa have been identified from Phytophthora ITS Clade 6. For representative isolates, the region spanning the internal transcribed spacer region of the ribosomal DNA, the nuclear gene encoding heat shock protein 90 and the mitochondrial cox1 gene were PCR amplified and sequenced. Based on phylogenetic analysis and morphological and physiological comparison, four species and one informally designated taxon have been described; Phytophthora gibbosa, P. gregata, P. litoralis, P. thermophila and P. taxon paludosa. Phytophthora gibbosa, P. gregata and P. taxon paludosa form a new cluster and share a common ancestor; they are homothallic and generally associated with dying vegetation in swampy or water-logged areas. Phytophthora thermophila and P. litoralis are sister species to each other and more distantly to P. gonapodyides. Both new species are common in waterways and cause scattered mortality within native vegetation. They are self-sterile and appear well adapted for survival in an aquatic environment and inundated soils, filling the niche occupied by P. gonapodyides and P. taxon salixsoil in the northern hemisphere. Currently the origin of these new taxa, their pathogenicity and their role in natural ecosystems are unknown. Following the precautionary principle, they should be regarded as a potential threat to native ecosystems and managed to minimise their further spread.

    Publication Date: 2024-01-12
    Description: This book provides an up-to-date survey of the biodiversity\nof the Netherlands. The treatment of all taxonomic groups\nwhich occur in the Netherlands forms the core (chapter 5).\nAround 100 specialists contributed to this unique survey.\nThe other chapters highlight many aspects of the Dutch\nbiodiversity: natural history (chapter 2), research (chapter\n3), classification (chapter 4), patterns (chapter 7), trends\n(chapter 8), government policy (chapter 10) and nature\nmanagement (chapter 11). In this summary we focus on the\ntaxonomic treatments. They show that even a small and\ngeologically relatively young country such as the Netherlands,\nharbours an immense diversity in life forms.\n\n[...]
