Zygomycete Identify

Hello to everyone i am identify some disease if i am wrong and some one have know them plz make sure to correct my thinking.

It' for sure a zygomycete, most probably Mucor, take in consideration also Rhizopus ( if you can identify specific structures rhizoids) or Rhizomucor ( sporsngiofores are not single, but ramificated).Is like Nigrospora.
But if Apergillus Niger un like that.( Coffee bean fungy).
Some my friend says.The sterigmas are not observed as in Aspergillus sp. Nigrospora sp. does not have conidiophores. It's Mucor sp.
