Name is type taxon for
Holotype n/n, Biogeology Clean Laboratory, University of California, Santa Barbara, California, USA
Figures: pl. 1, fig. 6
Note: Licari (1978): The holotype is located on thin section C250(39) from the Cloud Collection. Coordinates (21.4, 11.1).
Trichomes as described for the genus but of relatively small diameter (mean 2.5 μm of 109 trichomes measured) and possessing heterocyst-like cells. Morphologic characteristics are given in Table 2.
Refers to the great abundance of the small diameter trichomes.
The fossiliferous outcrops occur 2,900 m below the lowest metazoan trace fossils, are younger than 1.7 b.y. and are correlated to the Apache Group of Arizona, bracketed between radiometric ages of 1.2 and 1.4 b.y.

Unsurveyed NE¼ sec. 2, T19N, R10E, of Horse Thief Springs Quadrangle, California-Nevada (1:62,500). Elevation about 1,344 m.
