Notes:
Rare on Ile de la Possession. Only found in relatively wet (50-60%) soils sampled from cliffs near the seaside. No observations in mosses and water habitats.South Shetland Islands (Björck et al. 1993), King George Island (Schmidt et al. 1990), Antarctic Peninsula (Van de Vijver & Beyens 1997b).Taxon that can be included within the group of Tryblionella, considered by some authors to be a separate genus (Round et al. 1990).
