	abstract = {<p>ABSTRACT A strain of Gracilaria epihippisora Hoyle produces gall-like cell proliferations in culture. These growths can be excised and grown separately, where they retain an undifferentiated morphology and reach 5mm in diameter. The gall tissue consists of a single morphological cell type without any differentiation between surface and internal cells as is characteristic of normal thallus tissue. Gall cells are typically 20\&ndash;40 \&mu;m in diameter and contain the usual complement of organelles and a prominent vacuole, although there are several distinct features. The large multilobed plastids have an extensive proliferation of thylakoid membranes, which form an arrangement of loops and spirals. The thallus outer cell wall layer is highly reduced. The gall growths contain intracellular virus-like particles (ca. 80 nm in diameter) that occur in discrete groups.</p>
