 Oidium is a genus of Deuteromycetes, where traditionally most anamorphs of the order Erysiphales are included. Most of them are plant pathogens causing different forms of powdery mildew, for example:

  • Oidium arachidis (on peanut)
  • Oidium asteris-punicei (= Erysiphe cichoracearum) (on mangos)
  • Oidium balsamii = Erysiphe verbasci (on mulleins)
  • Oidium begoniae (=O.cyclaminis, O.lini, O.violae) = Erysiphe polyphaga (on Valerianella, Calluna and Erica)
  • Oidium candicans (= Monilia candicans)
  • Oidium caricae (on papayas)
  • Oidium caricae-papayae (on papayas)
  • Oidium caricicola (on papayas)
  • Oidium chrysanthemi = Erysiphe cichoracearum (on numerous plant species, especially Asteraceae)
  • Oidium carpini
  • Oidium chartarum (= Torula chartarum)
  • Oidium cyparissiae (= Acrosporium cyparissiae) (on cypress)
  • Oidium erysiphoides = Sphaerotheca fuliginea (on melons, watermelons and cucumbers)
  • Oidium euonymi-japonicae (on spindle-trees)
  • Oidium farinosum = Podosphaera leucotricha (on apples)
  • Oidium fructigenum = Monilia fructigena (on Rosaceae)
  • Oidium helichrysi (on strawflowers)
  • Oidium heveae (on rubber tree)
  • Oidium hortensiae = Microsphaera polonica (on bear's breeches and hydrangea)
  • Oidium indicum (on papayas and other tropical fruits)
  • Oidium lauracearum (on laurel)
  • Oidium lini ( = Euoidium lini)(on flax)
  • Oidium lycopersicum (on tomatoes)
  • Oidium mangiferae
  • Oidium manihotis
  • Oidium monilioides (=O.tritici)= Blumeria graminis (on cereals)
  • Oidium neolycopersici (on tomatoes)
  • Oidium oxalidis = Microsphaera russellii (on sorrels)
  • Oidium papayae (on papayas)
  • Oidium pullorum
  • Oidium sesami
  • Oidium tingitaninum
  • Oidium tuckeri = Uncinula necator (on grapes)
