A type of blue-green mold (Date of photograph unknown)
Penicillium fungal spores. Coloured scanning electron micrograph (SEM) of fruiting bodies of the fungus Penicillium roqueforti. These fruiting bodies (conidiophores) consist of branching chains of spores (conidia, bead-like structures). The mature spores germinate to form new fungi. Penicillium roqueforti is used commercially in the fermentation of blue-veined cheeses. Magnification: x310 at 6x7cm size.
