Remarks

The Palisada crustiformans (Fig. 4) specimen included in this study was sterile and matched previous descriptions by McDermid (1989) concerning vegetative characters. In particular, secondary pit connections between cortical cells were observed (Fig. 4C). Small structures that may or may not be ‘corps en cerise’, were also observed in cortical cells (Fig. 4B–C).
