SPECIES, AUTHORITY P. apiculatus Kalgutkar 1993, p. 84, pl. 4.3, fig. 11.
LOCATION Peel River, Yukon Territory, Canada.
ORIG DESCRIPTION* Spores light brown, fusiform-elliptical, tapering to a fine point at the base. Spores tetracellate, transversely septate, two central cells generally larger than the end cells. Septa thicker than the cell wall; septal folds and pores present. Some specimens with an intact hilum or a small portion of a subtending conidiophore were noted (pl. 4.3, fig.11). Spore size 25-38 x 7-13 µm.
COMMENTS* This species is distinct from other species of Pluricellaesporites van der Hammen 1954, emend. Elsik & Jansonius 1974 in its smaller size and pointed base. It shows a close affinity to the conidia of the extant dematiaceous fungus Phaeodactylium alpiniae in general morphology.

Etymology: From the Latin apiculatus, with a point, referring to the spores being pointed at their base.
