Fig 8. Microphotographs of fragmented marine organisms and hyphae forming haustoria.

(A) Marine sediments with remains of a likely diatom with a visible raphe across the center. (B) Remains of diatoms in marine sediments. The left diatom is overgrown by fungi and irregular organic matter, but structures resembling areolaes are visible through the organic cover. (C) Remains of a raphe and unidentified fragmented marine organism in marine sediments. (D) An unidentified fragmented marine organism surrounded by hyphae that form protruding haustorium penetrating the fragment. Haustorium is seen with the fragment as well. (E) A hyphae that forms a mycelial haustorium in association with the remains of a fragmented marine organism. For legends see caption of Fig 2.
