( Fig. 4 View Fig , Table 2)

Filaments with single trichome without sheaths in young cultures, and with one to two trichomes in a sheath in mature cultures, often form false branching. Trichomes straight, slightly curved, and constricted at the cross-walls. Sheaths firm or mucilaginous, colorless. Cells mostly shorter than wide or isodiametric, 1.8-3.3 μm wide, 1.0- 2.7 μm long. Apical cells rounded, up to 3.9 μm long. Involution cells slightly widened, rare, indistinctive. Slime caps extending outward from the apical cells, relatively clear.

Ecology. Biological soil crust on fine sand ( Pietrasiak et al., 2019), on cement wall in Korea.

Distribution. Chile ( Pietrasiak et al., 2019).

Site collection. Iui-dong, Yeongtong-gu, Suwon-si , Gyeonggi-do (37°18′18.2″N / 127°02′04.0″E) GoogleMaps .

Family Oculatellaceae Mai and J.R. Johansen, 2018 Genus Tildeniella Mai, J.R. Johansen and Pietrasiak, 2018

Filaments straight, flexuous or spirally coiled. Trichomes not attenuated towards ends, not constricted to slightly constricted at the cross-walls, with thin translucent cross-walls. Sheaths thin, firm, colorless. Cells longer than wide, apical cells rounded. Hormogonia and necridic cells absent.
