The order Mucorales consists of 13 families, 56 genera, and 300 species. Mucoralean fungi, or pin mold, is typically fast-growing, and generally found on food, with the most ubiquitous example being bread mold (Rhizopus stolonifer), or the equally common genus mucor, found in rotten vegetables or soil. In The Life Cycle of the Pin Mould we can see the development of fungi through the use of time-lapse photography, watching spores grow on an apple, cheese and porridge.
Made in 1943, The Life Cycle of the Pin Mould was originally intended for educational purposes, and is now one of 125 films currently being re-released by the British Council on Vimeo. Already available are films on London during wartime, hospitals, growing vegetables, the life cycle of a rabbit, the gardens of England and how to make a bicycle, amongst many others.
