FIGURES 8–19 in Parviphycus bompardii sp. nov. and P. albertanoae (Gelidiales, Rhodophyta), two species misidentified as Gelidiella ramellosa in the Mediterranean Sea

FIGURES 8–19. Parviphycus bompardii sp. nov.. Fig. 8. Paratype (CAT! 71) (Castelluccio, Syracuse, Sicily). Scale bar = 3 mm. Fig. 9. Paratype (BI! 38467) (Mola di Bari, Bari, Apulia). Scale bar = 4 mm. Fig. 10. Apical part of an erect axis covered by hairs (paratype CAT! 71). Scale bar = 155 μm. Fig. 11. Apex of an upright branch showing the distichous pattern of division of the subapical cells (isoparatype BI! 38466). Scale bar = 30 μm. Fig. 12. Irregularly arranged outermost cortical cells in surface view (paratype CAT! 71). Scale bar = 8 μm. Fig. 13. Transverse section of a compressed upright branch; seven cells (axial and periaxials) are aligned along the major axis in an evident row (paratype BI! 38467). Scale bar = 50 μm. Fig. 14. Longitudinal section of an erect axis: elongated axial and periaxial filaments composing the medullary region are well distinct from the isodiametric subcortical cells (paratype BI! 38467). Scale bar = 50 μm. Fig. 15. Apical and lateral tetrasporangial sori inserted at 90º on the axes (paratype BI! 38467). Scale bar = 650 μm. Fig. 16. Stichidium-like tetrasporangial branchlets constricted at their bases and shortly stalked (paratype BI! 38467). Scale bar = 230 μm. Fig. 17. Tetrasporangial sorus with tetrasporangia regularly arranged in chevrons (6 per row) and a steril margin (paratype CAT! 71). Scale bar = 100 μm. Fig. 18. An empty sorus in surface view: in the gaps of the outer cortex the tetrasporangium basal cells are visible (arrow). Regenerated tetrasporocysts (arrowhead) (paratype BI! 38467). Scale bar = 60 μm. Fig. 19. Longitudinal section of tetrasporangial sorus along the medullary row of axial and periaxial filaments forming a cubic-mesh network (paratype BI! 38467). Scale bar = 60 μm.
