Fusiformacysta salasii
Fusiformacysta salasii Morgan, 1975
Holotype: Morgan, 1975, pl.2, fig.4a-c
Locus typicus: Great Australian Basin, Australia
Stratum typicum: Early Neocomian

G.L. Williams short notes on species, Mesozoic-Cenozoic dinocyst course, Urbino, Italy, May 17-22, 1999 - LPP VIEWER CD-ROM 99.5.
Fusiformacysta salasii Morgan, 1975. With long conical apical and single antapical horn with bluntly rounded tip. The horns are similar in shape and size, the antapical horn may be shorter. Horn length is about one quarter of the total cyst length. There is no inner body and the autophragm does not show any tabulation. Archeopyle formed by the loss of two to perhaps five precingular plates. Size: 107-152 µm long, 33-51 µm wide.

Orignal description: Morgan, 1975, p. 161
Cyst is fusiform with long conical apical and single antapical horns which have bluntly rounded tips. The horns are similar in size and shape, the antapical horn sometimes being shorter; each is equal to about one quarter of the total cyst length. The autophragm shows no trace of tabulation. The cvst contains no inner body. The archeopyle is large, precingular, and formed by the loss of two to perhaps five individually separating reflected plates. The cyst is usually bent in the area near the archeopyle, so that the longitudinal axis is rarely straight.
Affinities:
Morgan, 1975, p. 161: This species differs from other fusiform cysts by having an autophragm, a large precingular archeopyle and a fine, uniform granulation.
