A haploid spore develops into a haploid hypha and then a larger haploid mycelium

Two haploid mycelia fuse

The mycelium that grows following fertilization (part 1) has both haploid nuclei (un-fused) and is therefore

When a heterokaryotic mycelium

grows a special structure that will eventuallly produce spores (e.g. a

mushroom), this structure is called a

Eventually there are two haploid nuclei inside a hypha, resulting in a diploid zygote

The diploid zygote produces haploid spores

Spores blow in the wind, landing in new habitat. In those phyla with

fruiting bodies, the spores are released from inside the fruiting body.
