SPECIES, AUTHORITY T. simplex (Elsik & Jansonius) Kalgutkar & Jansonius 2000
LOCATION Mackenzie Delta, N.W.T., Canada.
ORIG DESCRIPTION* Central cell wedge-shaped to rhomboid (attached to a narrow cylindrical hyphal cell in holotype); two straight lateral arms, wide at their base, tapering distally, slightly asymmetrically developed; septa indistinctly perforate or whole; secondary hyphae-like projections normally lacking (at least in known material). Dimensions: Span about 70 µm; complete arm 45 µm, 13 µm wide at base.
COMMENTS* Always rare, but several specimens known by now, all of the same morphology; in some specimens the lateral arms have hinged around the central cell and are more or less tightly appressed. The species may be morphologically intermediate between Ctenosporites and Pesavis tagluensis.

K&J REMARKS Pirozynski (1976b) suggested an affinity between Pesavis simplex and species of the dematiaceous fungus Ceratosporella [e.g. C. bicornis (Morgan) Höhnel 1923] (Ellis, 1971). Smith & Crane (1979) similarly proposed that P. simplex probably was a dematiaceous hyphomycete, closely similar to the living counterpart Ceratosporella bicornis, which occurs on dead or dying plant material. Pesavis tagluensis, however, they thought to be aero-aquatic, and belonging to a different group of fungi.
