It is a leaf more or less modified in form and structure that develops sporangia and may resemble and perform the functions of a foliage leaf, such as in many ferns. It may also be completely altered as in the spike of some members of Ophioglossum.

Sporophylls are also small foliaceous structures bearing the sporangia in a brown alga of the genus Alaria.
Sporophylls differentiated from vegetative leaves, most sporophylls fertile; megasporophylls and microsporophylls same size, in 4 alternating ranks, appressed, base usually with 2 diverging flaps or auricles, auricles protecting sporangia below.
Sporophylls deltate-ovate; apex keeled, strongly truncate in profile; bristle usually yellowish; margins short-ciliate to denticulate on distal 3/4.
Sporophylls ovate-lanceolate to lanceolate or seldom ovate; apex attenuate or slightly keeled, not truncate in profile; bristle usually whitish transparent, seldom yellowish (in old leaves); margins short-ciliate to denticulate on proximal 1/2, lacking cilia toward apex.
