Neogoniolithon sp.

( Fig. 4C)

DESCRIPTION

Thallus encrusting, monomerous, dorsiventral with coaxial ventral core. The cells of VC are 10 to 28 µm in length and 7 to 12 µm in diameter and PF cells are 9 to 20 µm in length and 5 to 11 µm in diameter. Cell fusions present both in VC and PF. Conceptacles uniporate, 550 to 600 µm in diameter and 200 to 300 µm in height. Epithallial cells not identified ( Table 1 ).

REMARKS

The species has the characteristic features of the genus Neogoniolithon , but this form is not comparable to any earlier known species of the genus, though, it has some resemblance with Neogoniolithon contii Mastrorilli, 1967 reported by Quaranta et al. (2007) from the Oligocene of NW Italy and northern Slovenia ( Gale 2009) including the transition from coaxial to non-coxial and cell fusions both in VC and PF ( Fig. 4C).
