Occurrence of morphologically barely distinguishable powdery mildew anamorphs on Oenothera spp. in different parts of the world}, year = {2014}, keywords = {Cryptic species, Erysiphe alphitoides, Erysiphe howeana, Invasive plant, ITS sequences}, doi = {}, url = {http://}, pmid = {}, journal = {Mycoscience}, volume = {}, number = {}, pages = {}, abstract = {To identify powdery mildew fungi infecting Oenothera spp. in Europe, specimens collected worldwide were examined based on morphology and internal transcribed spacer (ITS) sequences of the nuclear rRNA gene complex. The specimens were morphologically barely distinguishable from each other, each exhibiting pseudoidium-type conidiophores but sexual morphs lacking. Surprisingly, based on ITS sequence analyses, these represented two species, E. howeana, known to infect Oenothera spp., and Erysiphe cf. alphitoides, which has never been recorded on herbaceous plants. Both species were detected on the invasive O. biennis in different parts of the world including regions where O. biennis was introduced only recently.} }
