Fungus sporangiophores. Coloured scanning electron micrograph (SEM) of sporangiophores of a Pilobolus sp. fungus, growing on dung. A sporangiophore is a fruiting body formed on a specialised hyphal thread, at the end of which is a sporangium (dark brown). The sporangium is a sac-like container for fungal spores. When the spores are mature, the sporangium breaks, releasing the spores. The term Pilobolus means 'hat-thrower', referring to this spore discharge. This fungus typically grows on horse manure and other dung. Magnification: x59 at 5x7cm size.
