Mucor serpula Scopoli, Fl. Carn. ed. 2. 2:493. 1772.

 Description: Fructification plasmodiocarpous, in elongated winding or reticulate form, terete, bright yellow, tawny, or rusty, 0.3-0.5 mm in diameter. Peridium thin, transparent, dehiscent by bursting along the long axiles of plasmodiocarps, membranous, decorated on the inside surface with narrow bands in reticulate pattern as those found on spore surface. Hypothallus like the peridium, or a little darker in color. Capillitium a highly elastic net, orange yellow or yellow, the threads long , tangled, twisted, with few free ends, sparsely marked with long spines (2-5 μm) and 3-4 regular spiral bands, 4.0-7.5 μm in diameter, fine longitudinal ridges between two consecutive spiral bands distinct. Spores yellow in mass, globose, subglobose, marked with conspicuous, high ridges (banded reticulate) dividing the hemisphere into several large but irregular meshes, irregular ridges present in some, (9-) 10.0-12.5 (-14) μm in diameter.

 Note: A conspicuous species by its plasmodiocarpous fructification. The spiny capillitial threads and the coarsely reticulated spores also make this species distinctive. The specimen CHL B164 was harvested from a moist chamber culture and was found to have white plasmodium.
