Host genus Fungal species Symptoms and notes
Abies Delphinella abietis Causes needle blight
  Herpotrichia parasitica Parasitic on leaves (needles), causing browning of the tissues
Acer Pleuroceras pseudoplatani Causes irregular brown leaf spots on A. pseudoplatanus
  Rhytisma acerinum Tar spot of leaves, primarily of A. pseudoplatanus
  Sawadaea bicornis Powdery mildew of leaves
  Stegonsporium acerophilum A weak parasite, only reported from exotic Acer species in a cultivated environment
  Stegonsporium galeatum Presumably a weak pathogen, only reported from a cultivated exotic tree; possible threat to Acer pseudoplatanus
  Stegonsporium opalus Apparently a weak parasite, not known from native trees
  Stegonsporium protopyriforme Status unknown, a close relative of a weak pathogen. Only reported from a botanic garden and possibly introduced
  Stegonsporium pseudopyriforme Status unknown, a close relative of a weak pathogen. Only reported from a botanic garden and possibly introduced
  Stegonsporium pyriforme A weak pathogen causing death and dieback of Acer pseudoplatanus, especially of shaded branches
Agropyron Claviceps purpurea The ergot fungus, infecting inflorescences and forming sclerotia from modified seeds. Highly toxic
Anthoxanthum Claviceps purpurea As for that species on Agropyron
Astragalus Stigmatula astragali A biotrophic leaf parasite, probably not causing significant damage to the host
