This is a scanning electron microscope image of Penicillium chrysogenum, a species of fungus that can be found growing on salted food products in damp and warm conditions. Its hand-like appearance is created from its segmental anatomy, starting as tendon-like hyphae and finger-like sterigmata (orange) and ending with spores at the ‘fingertips’ (purple).
