Propagating Platycerium Through Spores

[David]

My P. corronarium had recently produced a spore patch. It has turned brownish in colour and I noticed brownish fuzzy stuff have been falling from it. I guess this is the spores.

So I placed a paper below the spore patch and disturb the brown fuzzy stuff under the spore patch with a pen to collect the spores. Have sprinkled the brown fuzzy stuff on top of wet sphagnum moss in an enclosed container and placed it under artificial lights.

Do I need to do anything else or just wait now? How does the gametophytes look like after they germinate? Do I need to keep the media very wet so that the sperm cells can swim through and reach the eggs? When is it advisable to fertilize the young sporlings?

Thanks. Would appreciate any advise
