Mesophyllum roveretoi Conti, 1943: 55 .

DESCRIPTION

Protuberances with a lumpy growth form.Thallus monomerous with presence of cell fusions in both VC and PF.The VC is coaxial ( Fig. 3F) and the cells of VC measure 14-20 µm in length and 8-12 µm in diameter. The cells of PF measuring 14-31 µm in length and 8-28 µm in diameter. Multiporate conceptacles are flat, 229-235 µm in diameter and 71-96 µm in height ( Table 1 ).

REMARKS

The features of thallus organization, growth form, anatomical features and nature of conceptacles are consistent with the description of Mesophyllum roveretoi provided by Basso et al. (2008) from the Miocene “ Lithothamnium Limestone ” of northern Croatia. The taxon stratigraphically ranges from the upper Eocene to the middle Miocene ( Conti 1946; Fravega et al. 1987) ( Table 2 ).
