hello there, this host is a dead stem of Chamerion angustifolium and the fungus could possibly be Diaporthe pardalota due to the stained background and the surrounding black line. However, the spores are too small and are not septate. Could the spores possibly be of the smaller conidial stage which is said to be called Phomopsis convallariae (from fungi.myspecies.info)?
or possibly am I being too ambitious in search of a species!
merci à tous
Alan

Re : Diaporthe pardalota?
Yes, this is a Phomopsis, but assigning it to a species is really problematic. Molecular phylogenetic studies suggest that the old morphology-based classification is poor, but there are still many species and there isn't a good broad study that focuses on material on natural substrata. Suggest you simply identify as Phomopsis sp.
Best wishes
Paul
