Abstract
A morphological account on the endosymbiosis between Amphiscolops sp and Amphidinium sp is given, based on scanning and transmission electron microscopy observations. The algal symbionts (15–20 µm in diameter) are found among cells of the peripheral parenchyma. Amphidinium sp. has a single pyrenoid of the multiple-stalked type, with several chloroplast lobes radiating from it. A comparison with A. klebsii is made. Our observations reinforce the assumption of selectivity of Amphiscolops for the symbiotic genus Amphidinium.
