Última 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...

Ano: 2008 URL: http://www.repository.naturalis.nl/record/532327 Novel species of Mycosphaerellaceae and Teratosphaeriaceae Naturalis Crous, P.W.; Summerell, B.A.; Carnegie, A.J.; Wingfield, M.J.; Groenewald, J.Z.. Recent phylogenetic studies based on multi-gene data have provided compelling evidence that the Mycosphaerellaceae and Teratosphaeriaceae represent numerous genera, many of which can be distinguished based on their anamorph morphology. The present study represents the second contribution in a series describing several novel species in different capnodealean genera defined in a previous study. Novelties on Eucalyptus from Australia include: Penidiella pseudotasmaniensis, P. tenuiramis, Phaeothecoidea intermedia, P. minutispora, Pseudocercospora tereticornis, Readeriella angustia, R. eucalyptigena, R. menaiensis, R. pseudocallista, R. tasmanica, Teratosphaeria alboconidia, T. complicata, T. majorizuluensis, T. miniata, T. profusa, Zasmidium aerohyalinosporum...

Ano: 2009 URL: http://www.repository.naturalis.nl/record/532086 Why everlastings don’t last Naturalis Crous, P.W.; Groenewald, J.Z.. The Cape Floral Region represents one of the world’s biodiversity hot spots, with a high level of plant, animal and insect endemism. The fungi occurring in this region, however, remain poorly studied. It is widely postulated that each plant species should harbour at least five to six unique fungal species, a number that we regard to be a huge underestimate. To test this hypothesis, we decided to study a single senescent flower of Phaenocoma prolifera (‘everlasting’; Asteraceae) collected in South Africa, and posed the question as to how many different species of fungi could be isolated and cultivated from 10 leaf bracts. Using a damp chamber technique, numerous microfungi could be induced to sporulate, enabling most of them to be successfully isolated on...

Ano: 2011 URL: http://www.repository.naturalis.nl/record/531877 Unravelling Mycosphaerella: do you believe in genera? Naturalis Crous, P.W.; Summerell, B.A.; Carnegie, A.J.; Wingfield, M.J.; Hunter, G.C.; Burgess, T.I.; Andjic, V.; P.A. Barber; J.Z. Groenewald. Many fungal genera have been defined based on single characters considered to be informative at the generic level. In addition, many unrelated taxa have been aggregated in genera because they shared apparently similar morphological characters arising from adaptation to similar niches and convergent evolution. This problem is aptly illustrated in Mycosphaerella. In its broadest definition, this genus of mainly leaf infecting fungi incorporates more than 30 form genera that share similar phenotypic characters mostly associated with structures produced on plant tissue or in culture. DNA sequence data derived from the LSU gene in the present study distinguish several clades and families in what has hitherto been considered to represent the Mycosphaerellaceae....
