Mucor

 

Colonies fast-growing, whitish to greyish, usually thick owing to the abundant upright sporangiophores. Spores (sporangiospores) produced inside spherical sporangia at the tips of the sporangiophores, brownish. Always with a large columella that remains after the sporangial wall is broken (a). Large dark zygospores may be produced. Common almost everywhere fungi occur. Ref: Schipper 1978
