Treatment for phycomycosis is very difficult and includes surgery when possible. Postoperative recurrence is common. Antifungal drugs show only limited effect on the disease, but itraconazole and terbinafine hydrochloride are often used for two to three months following surgery. Humans with "Basidiobolus" infections have been treated with amphotericin B and potassium iodide. For pythiosis and lagenidiosis, a new drug targeting water moulds called caspofungin is available, but it is very expensive. Immunotherapy has been used successfully in humans and horses with pythiosis. Treatment for skin lesions is traditionally with potassium iodide, but itraconazole has also been used successfully.

Basidiobolomycosis is a fungal disease.

It is caused by "Basidiobolus ranarum".

Treatment with itraconazole has been described.

The term oomycosis is used to describe oomycete infections. These are more common in animals, notably dogs and horses. These are heterokonts, not true fungi. Types include pythiosis (caused by "Pythium insidiosum") and lagenidiosis.

Zygomycosis has been described in a cat, where fungal infection of the tracheobronchus led to respiratory disease requiring euthanasia.

Pathogenic zygomycosis is caused by species in two orders: Mucorales or Entomophthorales, with the former causing far more disease than the latter. These diseases are known as "mucormycosis" and "entomophthoramycosis", respectively.

- Order Mucorales (mucormycosis)

- Family Mucoraceae

- "Absidia" ("Absidia corymbifera")

- "Apophysomyces" ("Apophysomyces elegans" and "Apophysomyces trapeziformis")

- "Mucor" ("Mucor indicus")

- "Rhizomucor" ("Rhizomucor pusillus")

- "Rhizopus" ("Rhizopus oryzae")

- Family Cunninghamellaceae

- "Cunninghamella" ("Cunninghamella bertholletiae")

- Family Thamnidiaceae

- "Cokeromyces" ("Cokeromyces recurvatus")

- Family Saksenaeaceae

- "Saksenaea" ("Saksenaea vasiformis")

- Family Syncephalastraceae

- "Syncephalastrum" ("Syncephalastrum racemosum")

- Order Entomophthorales (entomophthoramycosis)

- Family Basidiobolaceae

- "Basidiobolus" ("Basidiobolus ranarum")

- Family Ancylistaceae

- "Conidiobolus" ("Conidiobolus coronatus/Conidiobolus incongruus")

Entomophthoramycosis (or Entomophthoromycosis) is a mycosis caused by Entomophthorales.

Examples include basidiobolomycosis and conidiobolomycosis.
