Lanternosphaeridium mutinense
Lanternosphaeridium mutinense Corradini, 1973, p.155-156
Originally Lanternosphaeridium, subsequently Fibrocysta?.
Taxonomic senior synonym: Hystrichosphaeridium (as Corradinisphaeridium) horridum, according to Masure (1986, p.112).
Holotype: Corradini, 1973, pl.23, fig.2
Locus typicus: Viano, Reggio Emilia, Italy
Stratum typicum: Senonian
Original diagnosis: Corradini, 1973, p. 155-156
Ovoidal central body with smooth endophragm and smooth to finelv granular periphragm, sometimes perforated. Long solid processes distally blunted. Large apical process, irregularly branched, the antapical one considerably developed.
Apical and / or antapical horns present on the inner body. Precingular archeopyle.
Dimensions--Holotype: diameter of the central body 68x80 Ám, length of the processe 20-42 Ám. Range: diameter of the central body 50(65)72x55(78)88 Ám, length of the processes 18(32)48 Ám.
Original description: Corradini, 1973, p. 156
From the roughly ovoidal test arise some fourty well developed processes.
The simple ones taper gradually from the base to the apex and are distally blunted. In the cingular region, particularly, adjacent processes are in close contact and united along the two-thirds of their length. They branch them normally in two blunted appendages which are sometimes also irregularly branched. The processes have usually fairly broad bases which are connected proximally with the adyacent processes by low crests.
The processes may occasionally be slighsly perforate.
The apical process is normally very strong and medially branched in irregular pattern. Appendages of the branches mav be simple, furcate or digitate and are distaliv acuminate or blunted.
One appendage, which usually is the longest one, is bulbous and may present short spines.
Antapical process is also larger than normal processes and its division into three or four simple appendages, different in length, takes place medially. Appendages are blunted distally, the longest ones being sometimes acuminate.
Low crests connecting the bases of adjacent processes delimit, more or less markedly, an elonged area corresponding to the sulcal region.
Inner body with apical and antapical horns, more or less protracted into the bases of the apical and antapical processes.
Precingular archeopyle mostly present, formed by the loss of one or two dorsal adjacent plates.
Affinities:
Corradini, 1973, p. 156: L. mutinense differs from all previously described species by the lack of fibrousness of the periphragm and / or by the length of the processes.
