FIGURE 2. Light microscope views of Aetokthonos hydrillicola. A. Fluorescence microscopy of A. hydrillicola on leaf of Hydrilla, scale = 100 μm. B. Fluorescence microscopy of thallus morphology in culture, scale = 100 μm. C–D. Fluorescence microscopy of branching filaments, arrows show hormogonia production in sheath, Scale = 10 μm. E. Thallus showing apical caps (black arrow) and thick-walled enlarged cells possibly functioning as akinetes (white arrow), scale = 10 μm. F–G. Thallus showing typical branching pattern and dehiscent apical cells (hormocytes?) (arrows), scale=10 μm.
