Hystrichosphaeridium mineralosum ssp. labiatum
From Fensome et al., 2019:
Hystrichosphaeridium mineralosum ssp. Iabiatum Varma and Dangwal, 1964, p.64–65, pl.1, figs.10–11. Holotype: Varma and Dangwal,
1964, pl.1, fig.10. Age: Eocene–Oligocene.
---------------------------------------------------------------------------------------------------
Original diagnosis: Varma and Dangwal, 1964, p.64
Body originally spherical, densely granulate, looking somewhat like an aggregation of mineral matter as in H. mineralosum s. s., dark-brown in color. Body wall is concealed. Processes hollow, straight, unbranched, stiff to slightly supple, and radiating from all over the body at moderate distances from each other. Bases of the processes broad, the upper part of the processes narrowing down very slightly towards the tips, which are open and have a thickened liplike structure all round.
Measurement: Diameter of body ca. 39 µm; length of processes ca. 7.8 µm.
Affinities:
Varma and Dangwal, 1964, p.64: Essselltially these forms belong to H. mitleralosum The lipped processes of this subspecies are quite distinct from any other noted in the present study.
