Fungi Life Cycle

The stalk and cap model of fungi start life as an egg-like bulb

Spores, produced in the gills, are then dispersed throughout its surroundings, and begin the process described above.

Spores produced by mature fungi are released into the surrounding environment, where they divide and grow into hyphae. Hyphae are root-like threads composed of haploid cells. When two hydra of opposite strain (+/-) come into contact, the two cell types fuse to create one cell with two nuclei. This fused cell grows into the fruiting body, also known as the mushroom. The mushroom body is therefore composed entirely of cells with two nuclei. In order to sexually reproduce, and create spores, the nuclei in the cells of the hymenium undergo a series fusions and divisions. First the nuclei fuse to form diploid cells, and then each cell undergoes meiosis to form haploid cells. These haploid cells are the spores produced by fungi.
