Bulblet fern has two means of reproduction. The green knot-shaped structures are bulblets; these break off and grow into new ferns. The pale whitish structures bear spores (the standard means of fern reproduction). The white fibers are spider web, not part of the fern.

Bulblet fern fronds are long and narrow, tapering very gradually to the tip. The ruler shows inches.
