Aseroe, the flower fungus, has a white stalk-like base and several tapering bright red arms. Aseroe has free arms, and at the top of the stalk there is a flat, perforated disc, from which the paired arms arise.

Saprobic on soil and litter. Often in disturbed sites in natural areas.

Anthurus is very similar, distinguished by the lack of a flat disc and by the arms often remaining joined at their tips. The forms common on garden mulch often vary in the pairing and number of arms.

Anthurus and Aseroe are similar stinkhorns with a white stalk-like base and several tapering bright red arms. Anthurus characteristically has the arms joined at the top, but the number of arms and persistence of the joining of the arms varies somewhat in New Zealand material. Aseroe has free arms, and at the the top of the stalk there is a lateral disc, from which the arms are said to arise. In both taxa, there is copious, brown slime on the inside of the base of the arms.

Saprobic on soil and litter. Often in disturbed sites in natural areas, and very common on wood chip mulch in urban areas.
