SPECIES, AUTHORITY T. elongatus Ke & Shi 1978, p. 50, pl. 5, fig. 17.
LOCATION Cangxian, Hebei Province, Coastal region of Bohai, China.
ORIG DESCRIPTION* Spore about 50 µm in size, longest extension measuring 35 x 11 µm. Spore outline elongated triangular, sides of triangle of unequal length. The end of the spore that is entire consists of 7 cells, the shortest end has only one cell (i.e., one cell remains), while the third end is observed to have four cells (i.e., four cells remain). The cells gradually diminish in size from the base to the ends of the spore. Spore triporate, pores situated at apex of each end (pore indistinct at four-celled end of spore). Pores 2.5 µm in diameter. Most of the septa hyaline. Spore wall about 1 µm thick, stratification obscure. Surface psilate.
COMMENTS* This species is distinguished from the other two species of this genus by the fact that the spores have elongated corners, giving them a trifurcate shape.

K&J REMARKS Triporicellaesporites elongatus seems to be almost identical in appearance to T. simplex (Elsik & Jansonius) comb. nov., having a central cell and two straight lateral arms. The triporate nature is not clearly demonstrated in the illustrated specimen (pl. 5, fig. 17). See also remarks from Kalgutkar and Jansonius (2000) under T. simplex.
