with one pore, urn-shaped, 400 [micro]m long and 310 [micro]m in diam.
In the present study, the effect of grazing refuges was clearly visible on some specimens of the fruticose Mesophyllum printzianum, where pockets of diatoms proliferated in the narrow gaps between protruberances or the sunken pore plates of conceptacles
Fucoid algae release male and female gametangia (antheridia and oogonia) through multicellular pores to the surface of the alga from spherical, subepidermal conceptacles
present throughout the reproductive tissue (receptacles, Fritsch 1945).
