15(14) Sporoclades lateral. Sporangiophores usually yellowish. (No parasitism has been demonstrated, but in culture grows much better in the presence of the white, garlic-smelling _Mortierella_ spp.). _Coemansia_ (fig. 82) e.g. spores 6-11µm long; sporoclades spirally arranged around the axis - _C. erecta_ spores 16-18µm long; sporoclades formed on one side of the axis, causing it to curve to one side - _C. scorpoidea_ - Sporoclades produced in a terminal verticil. Sporangiophores shining white. _Kickxella alabastrina_ (fig. 83) 16(14) Spores produced in clusters below the apex of the final branches of a compound, often trifid, branching system which is given a bristly appearance by the projecting tips. Superficially similar to _Thamnidium_ or _Helicostylum_. Capable of parasitising, and growing much better in association with, other Mucorales. _Chaetocladium_ (fig. 74) e.g. spores smooth, 4-6µm diam. - _C. brefeldii_ spores echinulate, 6.5-9.5µm - _C. jonesii_ - 'Spores' not produced in subterminal clusters, but terminally on lateral vesicles, or over the surface of swollen fertile regions of the sporangiophore. 17 17(16) Sporangiophores up to 250µm high. Lateral vesicles numerous, each producing a single 'spore', which is projected when mature. Parasitic on tardigiades. _Ballocephala_ (fig. 86) - Sporangiophores visible with the unaided eye. Spores produced on swollen parts of the sporangiophore. 18
