Phallaceae is a family of fungi, commonly known as stinkhorns, within the order Phallales. Stinkhorns have a worldwide distribution, but are especially prevalent in tropical regions. They are known for their foul-smelling, sticky spore masses, or gleba, borne on the end of a stalk called the receptaculum. The characteristic fruiting-body structure, a single, unbranched receptaculum with an externally attached gleba on the upper part, distinguishes the Phallaceae from other families in the Phallales. The spore mass typically smells of carrion or dung, and attracts flies, beetles and other insects to help disperse the spores. Although there is great diversity in body structure shape among the various genera, all species in the Phallaceae begin their development as oval or round structures known as "eggs". The appearance of Phallaceae is often sudden, as gleba can erupt from the underground egg and burst open within an hour. According to a 2008 estimate, the family contains 21 genera and 77 species.

In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. They were thought to have appeared as early as the mid-late Ordovician period as an adaptation of early land plants.

The last stage of the moss lifecycle is shown, where the sporophytes are visible before dispersion of their spores: the calyptra (1) is still attached to the capsule (3). The tops of the gametophytes (2) can be discerned as well. Inset shows the surrounding, black poplars growing on sandy loam on the bank of a
