Surculosphaeridium ?subsp. granulosum Jain, 1977b, p.183, pl.6, fig.76.
Originally Surculosphaeridium cribrotubiferum subsp. granulosum, subsequently (and now) Surculosphaeridium cribrotubiferum? subsp. granulosum.
Questionable assignment: Fauconnier and Pourtoy in Fauconnier and Masure (2004, p.518).
Holotype: Jain, 1977b, pl.6, fig.76.
Age: early Albian

Original description: [Jain, 1977b]:
Surculosphaeridium cribrotubiferum (Sarjeant) Davey et al., 1966 subsp. granulosum nov.
PI. 6, fig. 76
Description - Central body subspherical, periphragm coarsely granulate, covered with long, perforate, variously branched processes, some are deeply branched giving an appearance of 4-5 processes per plate. Archaeopyle apical, margin deeply notched.
Measurements
Central body diameter 42 μm
Length of processes upto 24 μm
Comparison - Present forms differ from S. cribrotubiferum (Sarjeant) Davey et al. in having granular periphragm and deeply notched archaeopyle margin.
