Assessment Notes

Taxonomic notes

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).
