Pannosiella
From Williams et al., 2017:
[Pannosiella, Batten and Lister, 1988, p. 347
Type species: Pannosiella perforata, Batten and Lister, 1988 (fig.2f)]
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description: [Batten and Lister, 1988]:
Diagnosis:
Small, subspherical to ovoid skolochorate cyst with or without a small apical prominence. Wall two-layered. Processes numerous, long, flexous, distally closed, perforate in transmitted light; either simple, of varying width, or broad and irregularly shaped with lateral spinose outgrowths, tapered, or with variously branching terminations; distribution paratabular but alignment not always evident. Non-tabular processes may also occur. Archeopyle precingular.
Affinities:
This genus differs from the acritarch Baltisphaeridium Eisenack, 1958 in displaying a paratabular distribution of processes, a precingular archeopyle and, occasionally, a small apical prominence, all of which demonstrate its dinoflagellate affinity. The distinctive morphology of the processes, which are relatively long in comparison with the diameter of the central body and very variable in form, serve to distinguish it from all other skolochorate dinocyst genera.
