     Large clumps of Psilotum can easily be divided, but it often seems to do 
better when crowded (over-divided and overpotted plants sometimes grow ok
but stop sporing for a long time).  Small pieces from  a clump taken along 
with their rhizomes are very  hard to establish.    Spores can be grown, but 
are very slow;  I saw a recipe by Bierhorst  that basically involved sowing 
the spores into old soil in a pot of Amaryllis or other plant (The mycotrophic 
gametophytes and rhizomes of Psilotum survive well in crowded  pots of other 
plants, and often one sees many volunteers in greenhouses).
