Ectocarpus (Phaeophyceae)

Ectocarpus fasciculatus -- plurilocular sporangium, either haploid gametangium or sporangium. The haploid sporangium is initiated on the diploid sporophyte by meiosis. In both cases the gametangium and sporangium mature through sequential mitotic divisions. Tidepool (large salinity variability), Portsmouth, NH USA collected by Francoise Morison
