Trying to interpret those photos, I get the impression that the germination is 
epigeal.  The Lily seeds that I've grown were definitely epigeal.  If the parts 
that are visible in your photos are the radicle and protobulb, then the 
cotyledon is still in the seed shell, and as it expands, it will push the seed 
husk above ground.

This are Lilium canadense seeds in the first stage of germination. It is a 
delayed hypogeal species and has been in warm stratification (69 deg F) for 30 
days as have the others. 

Another delayed hypogeal species, Lilium michiganense, with exactly the same 
timing in warm strat as above. The bulb like structures at this stage of 
germination is interesting to watch.

This species, Lilium philladelphicum, appears to be putting out a radicle rather 
than the bulb like structures above.

I've been checking these seeds in warm stratification every 7 days. I'll hold 
them in warm strat for another week at slightly cooler temperatures, then move 
to cold and watch carefully for 3 months. If the root continues to develop I'll 
plant in a container and hold in cool conditions until they begin to emerge.
