Hystrichosphaeridium picorricum
Hystrichosphaeridium picorricum (Cramer, 1964) Andreeva, 1973
Combination not validly published, since Andreeva, 1973, did not fully reference the basionym.
Originally Micrhystridium, subsequently Multiplicisphaeridium, thirdly Hystrichosphaeridium (combination not validly published).
Tax. jr. synonym of Baltisphaeridium (now Multiplicisphaeridium) cladum Downie, 1963, according to Colbath, 1979.
Andreeva, 1973, implied that the basionym for this species is Hystrichosphaeridium picorricum.
Holotype: Cramer, 1964, pl.11, fig.2
Age: Devonian (Middle Siegenian-Emsian)
Original description (Cramer, 1964)
Dimensions Oi = about 15 µ; Ot = 25-40 µ (30µ).
Central body hollow, subspherial. Numerous processes present. These processes show a great variation in form; 15-20 processes in optical section. The variations in form of the processes seem to have no stratigraphic use in the region investigated. Frequency and provenance. Rare in the La Vid Shale Member. Holotype from 0823, La Vid de Gordón, NW-Spain. Known stratigraphical range. La Vid Shale Member, Middle Siegenian to Emsian (part), NW-Spain.
