Fertilization at once takes place, by the direct union of protoplasm. Eight or ten branches grow out just below the carpogone, and growing upward soon completely cover it with a cellular coat which eventually becomes hardened and turns brownish in color, constituting the pericarp of the spore-fruit (Fig. 81)..
