 Actinomortierella wolfii was earlier called Mortierella wolfii and was then placed in the phylum Zygomycota, but this phylum has now been divided into two phyla: Mucoromycota and Zoopagomycota.
Macromorphology (smell): A. wolfii forms characteristic white and velvety colonies with uneven edges. The colonies can have a diameter of 5 cm after about 5 days of incubation.
Micromorphology: A. wolfii can be induced to sporulate by subculturing on a nutrient-deficient medium such as hay-infusion agar.
The sporangiophores are erect and very delicate because they are long (100-250 µm) and narrow (5-20 µm). Sporangia are 15-50 µm in diameter and sporangiospores are 6-10 x 3-5 µm.
