FIGURES 10–16. Morphological features of Hassallia littoralis. Fig. 10. Terminal widening of the sheath. Fig. 11. Branched filament with evident cytoplasmic granules. Fig. 12. A trichome with variations in diameter bearing a darker, shortened necridial cell. Fig. 13. Plane view of a cylindrical trichome and filament. Fig. 14. Intense terminal EPS production by highly granulosed trichome with an open sheath. Fig. 15. Darkening of hyaline sheath produced probably by gelatinization. Fig. 16. A trichome of a young filament with necridic cells and sheath widening. Scale bars: 6 µm.
