The marine yellowish-green alga (strain PP983), often ellipsoidal, occasionally spherical, 3-4μm long, 2. 5-3μm wide, contains one nucleolus. Morphological features and pigment composition analysis showed that this alga was a new species of the Xanthophyta and was named as Ellipsoidion maratilis Shi et Hu.
