The answer is Haploid spores germinate to give rise to protonema, which later develops into a sporophyte.

A protonema (plural: protonemata) is a thread-like chain of cells that forms the earliest stage (the haploid phase) of a bryophyte life cycle ...

A haploid gametophyte (each of whose cells contains a fixed number of unpaired chromosomes) gives rise to a diploid sporophyte,. Gametophytes produce haploid sperm and eggs which fuse to form diploid zygotes that grow into sporophytes.
