Rhizopus stolonifer is characterized by producing long sporangiophores (up to 3-4 mm long) that commomly arises from stolons with opposite and strongly branched rhizoids. Multisporous sporangia are frequently over 100 μm diam, with a discrete apophysis, and mostly deliquescing in water, leaving no collar.  Sporangiosores are ovoid, subglobose, some irregular (angulate), distinctly striate. Giand cells are absent. Zygoporangia are usually black and with ornate wall (Zheng et al 2007). It belongs to the sub-kingdom Mucoromyceta, phylum Mucoromycota, family Rhizopodaceae, order Mucorales (Tedersoo et al. 2018).

There are several records worldwide of this species. I suggest it as Least Concern (LC).

The species in known in 18 countries. In Brazil, it is know in 4 of the 26 states.

This species has a worldwide distribution. here are about 74 records of this species in GBIF,  and 132 in PlutoF.

Reported on soil, herbivore dung, fruits, flowers and decaying root.

In Brazil, this species is moslty recorded in the Atlantic Forest, a hotspot with some reports in Cerrado em Caatinga domains.

The species, even occurring in all biomes, has a fragmented distribution in Brazil. Studies about its population distribution are needed.
