Microsphaeridium
From Williams et al., 2017:
[Microsphaeridium, Benedek, 1972, p. 46-47
Acritarch genus, according to Stover and Evitt, 1978
Type species: Microsphaeridium ancistroides, Benedek, 1972 (pl.12, figs.3a–b)]
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description: [Benedek, 1972]: (Translation: LPP):
The round to oval capsule has a smooth, untabulated surface. The surface is covered by a few hollow, very long and at the tip closed, multifurcate processes, which have influence on the shape of the capsule at their base. The length of the processes exceeds the cyst diameter. Pylome until now unknown.
