Introduction
Spore
preservation is the most stable method. A mature sporangium is harvested, dried
and stored at 4˚C. A sporangium contains thousands of spores. We have
confirmed that spores can be stored for at least 4 years under this condition,
and should be stable longer.
1. Cultivate
gametophores at 15˚C under short-day conditions (8L16D) and induce
sporophyte formation .
2. After
development of a brown sporophyte at the apex of a gametophore, cut the seta of
the sporophyte with a scalpel and forceps, and separate the sporangium from the
gametophore. Do not cut green sporangia that have not yet matured.

3. Collect
sporangia into a microtube and air-dry them for a couple of days.
4. Store at 4˚C.
