“Une Mucorinée purement conidienne, Cunninghamella ajri- 
cana” is the title under which Matrucuor (J. c.) has described an 
Oedocephalum-like fungus which on morphological and physiologi- 
cal grounds he considered was to be included among the Mucorineae. 
The species had been previously described by THAXTER, however, as 
Oecdocephalum echinulatum, and with this name has been included 
among the Oedocephalums in Saccarno’s Sylloge, where the simi- 
larity to Choanephora is pointed out. 
The mucors are typically coenocytes with a non-septate mycelium 
at least in the early stages of development, with sexually formed 
“Ygospores, and with the characteristic production of endogenous 
non-sexual spores within sporangia. The absence of septa in the 
hyphae of the species under consideration led MaTRucHor, despite 
the lack of sporangia or zygospores, to believe that he might be deal- 
ing with a member of the Mucorineae. Piptocephalis, which is an
