Initially this taxon was described as a variety of Mallomonas cratis K.Harris & D.E.Bradley, M. cratis var. asmundiae Wujek & van der Veer, and later it was raised to the rank of species. In Mallomonas asmundiae the dome is ornamented by the parallel ribs whereas in M. cratis the ribs are U-shaped. Additionally, the scales of M. asmundiae have pronounced lateral incurvings and a more densely striated posterior flange (Siver 1991).
