Photomicrograph of Penicillin chrysogenum, 3 days old, grown on potato dextrose agar medium (red). The grey, central areas of the colonies represent the sporangia, the mould's spore-forming bodies. The outer, white areas are the hyphae, collectively forming the mycelium, which supports the sporangia by obtaining nutrients. P. chrysogenum was utilised in early methods of commercial antibiotic production. Magnification: X 1.2 at 35mm size.
