I founded it in a wet evening. This is some mold growing up on a feces (maybe of a dog) with a lot of drop for the dew. Spinellus fusiger, commonly known as the bonnet mould, is a species of fungus in the Zygomycota phylum. It is a pin mold that is characterized by erect sporangiophores (specialized hyphae that bear a sporangium) that are simple in structure, brown or yellowish-brown in color, and with branched aerial filaments that bear the zygospores.
