Notes:
Fairly common in both mosses and freshwater habitats. Sample W550, a slightly acid lake with low spec. conductance value) yielded almost 99% of this taxon. Prefers very wet, terrestrial mosses (F-value III).South Georgia (Van de Vijver & Beyens 1996), Maritime Antarctic Region (Van de Vijver & Beyens 1997b), Kerguelen (Bourrelly & Manguin 1954, Le Cohu & Maillard 1986), South Orkney Islands (Oppenheim 1990, Oppenheim & Greenwood 1990, Jones et al. 1993, Jones & Juggins 1995), South Shetland Islands (Kawecka & Olech 1993, Kawecka et al. 1998), King George Island (Schmidt et al. 1990).
