Description:
This class includes motile naked and non-motile silicified cells. Motile cells with two Parmales diversity and distribution M Ichinomiya et al 2431 The ISME Journal unequal flagella, ventrally inserted. Long flagellum directed forward, with tubular flagellar hairs. Short flagellum naked and acronemated. Basal apparatus reduced to basal bodies. Transitional helix absent. No eyespot. Non-motile cells with silicified cell wall composed of five or eight plates, all fitting edge to edge. All cell walls composed of shield plates, girdle plates and a ventral plate. In addition, a dorsal plate is usually present. For both motile and non-motile cells, one chloroplast with a girdle lamella, lamellae with two to three appressed thylakoids. Mitochondria with tubular cristae. Pigment composition includes chlorophyll a, c1+c2 and c3 and fucoxanthin as a major carotenoid. 18S rRNA gene sequences place this class as a sister group to the diatoms.

Taxonomic notes:

According to Ichinomiya et al. (2011:147, 148), the Parmales should be taxonomically separated from the Chrysophyceae and their molecular phylogenetic analyses suggest that this order is closely related to Bolidophyceae. They consider that there is a close evolutionary relationship between Parmales, Bolidophyceae, and diatoms. This order has also been included in the Synurophyceae.
