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 alphitoides (= O. quercinum) = Microsphaera alphitoides (on oaks)
* Oidium anacardii (= Acrosporium anacardii) (on cashew)
* 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 cornsalad, 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)
Oidium albicans has been a parallel name of the yeast Candida albicans (not related to the powdery mildew).
Some other species of medical importance previously classified as Oidium include:
* Oidium cutaneum = Trichosporon cutaneum (cause of some human fungal diseases)
* Oidium lactis (=Oidium pulmoneum) = Geotrichum candidum (in soil, water and air, also belongs to normal human flora)
