Hystrichosphaeridium toyetae
Hystrichosphaeridium toyetae (Cramer, 1964) Lardeux, 1976
Now Florisphaeridium. Originally Baltisphaeridium, subsequently Multiplicisphaeridium?, thirdly Hystrichosphaeridium, fourthly (and now) Florisphaeridium.
Holotype: Cramer, 1964b, pl.1, fig.15
Age: Devonian (Middle Siegenian-Emsian)
Original (Cramer, 1964):
Baltisphaeridium toyetae n. sp. Plate I: 14, 15*; text-figure 22: 7 and 7a.
Dimensions. Ø= 30—60 µ; Ø= up to 200 µ, usually much smaller.
Central body and processes hollow with uniform walls. The central body is roughly spherical, very thin walled. It has usually wrinkled walls. The walls are psilate at 1200 x magnification. The processes in the form of broad-based pilars show roset-like structures at the tips. Number of processes 2 to 6 (3). The specimens are very transparent.
Frequency and provenance. Rare in the La Vid Shale Member. Holotype from 0710, Géras de Gordon, NW-Spain.
Known stratigraphical range. La Vid Shale .Member, Middle Siegenian to Emsian (part), NW-Spain.
Similar forms. B. pilar n. sp. has processes with different terminal structures and is not psilate.
