New data on the reproductive structures of Spatoglossum solieri (Chauvin ex Montagne) Kützing (Dictyotales, Phaeophyceae)

Keywords: anatomy, Dictyotales, morphology, reproduction, Spatoglossum

A detailed vegetative and reproductive study of the little known species Spatoglossum solieri, using both fresh material and herbarium specimens, showed that the reproductive structures hitherto described as oogonia in S. solieri correspond, in fact, to undivided sporangia. Oogonia of S. solieri are reported and described for the first time in the present paper. They can be distinguished from undivided sporangia by their shape, the presence of a pedicel consisting of 1–2(3) basal flat cells and because they protrude up to half their length above the blade surface. Sporangia appeared as sessile structures, although they sometimes show a single lenticular stalk cell laterally placed. Likewise, and contrary to the published data, this study showed that antheridia are pedicellate structures.
