Fibrocysta licia
Fibrocysta licia (Jain et al., 1975) Stover and Evitt, 1978
Originally Lanternosphaeridium, subsequently (and now) Fibrocysta.
Holotypus: Jain et al., 1975, pl.4, fig.51
Locus typicus: Assam, India
Stratum typicum: Danian
Original diagnosis: Jain et al., 1975, p.10: Lanternosphaeridium licium
Cyst ellipsoidal to ovoid, broadly convex, bilaterally symmetrical, chorate, endophragm smooth; periphragm ornamented with long, thread like or broad fiberous processes arranged all over, closed both distally and proximally. Surface coarsely granulate; process size and distribution irregular, apex truncate to pointed or bifid; periphragm extending apically and antapically forming single apical and antapical horn, part of endophragm extends into horns. Cingulum region discernible only due to densely arranged processes and occasional folds. Archaeopyle more or less rectangular, precingular, broad.
Dimensions: Holotype: Cyst size (including processes) 130x90 Ám, apical horn length 20 Ám, antapical horn length 20 Ám, wall thickness 1.5-2 Ám, length of processes 10-30 Ám; Range: Cyst size (including processes) 90-130x80-90 Ám, apical horn length 20-25 Ám, antapical horn length 20-25 Ám, wall thickness 1.5-2 Ám, length of processes 10-30 Ám.
