SPECIES, AUTHORITY T. setifer (Cookson) Saxena & Misra 1990, p. 270.
LOCATION (Cookson) Australia, New Zealand and the Kerguelen Archipelago; (Saxena & Misra): Ratnagiri beds, Amberiwidi section, Sindhu Durg District, Maharashtra.
ORIG DESCRIPTION* (Cookson) Ascomata flattened-hemispherical with a somewhat sinuous outline, 70-135 µm in diameter, solitary, composed of radiating hyphae connected throughout their whole length. Cells approximately 4-13 µm long and 4-10 µm thick, frequently becoming more elongated towards the periphery. Cell walls of the majority of cells thin, but the outer walls of the peripheral layer frequently strongly thickened to form the firm, entire margin of the ascoma. The ostiole is well defined, distinctly elevated and either centrally or slightly eccentrically placed. It is 10-16 µm in diameter and bordered by three or four layers of dark brown, thick-walled cubical cells. The border is cylindrical and some of the cells bear setae, and their walls are thick and brown below, thinning towards lighter, bluntly-pointed apices (pl. 11, fig. 4).
COMMENTS* (Cookson): In its typical form N. setifer strongly resembles the living species Chaetothyriopsis panamensis Stevans & Dorman (Stevens, 1927) from Panama-Darien, the border of the ostiole and the development of setae being features common to both. The setae of C. panamensis, however, are considerably longer and apparently less numerous than are those of N. setifer.

K&J REMARKS Cookson gave the epithet as "setiferus"; the correct form of this adjective in singular masculine first case is "setifer."
