Última Co-occurring species of Teratosphaeria on Eucalyptus Naturalis Crous, P.W.; Groenewald, J.Z.; Summerell, B.A.; Wingfield, B.D.; Wingfield, M.J.. A common leaf spot disease occurring on Eucalyptus cladocalyx and E. lehmannii in the Western Cape Province of South Africa is known from literature to be caused by the fungus Coniothyrium ovatum, which is a pathogen native to several eucalypts in Australia. Recent collections have shown that Australian material identified as C. ovatum is morphologically and phylogenetically distinct from the South African specimens, and that all these taxa would be better accommodated in the genus Teratosphaeria. South African specimens previously identified as C. ovatum were found to represent two species that co-occur in the same leaves and even spots and are described here as T. juvenalis and T. verrucosa. Furthermore, a fresh collection of T. ovata from E. phoenicea...

Ano: 2009 URL: http://www.repository.naturalis.nl/record/532187 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....
