Liochlaena subulata is a rare liverwort in North America and Europe, but relatively common in Asia. In Europe it was reported for the first time in 1969. To date, L. subulata had only one locality in north-western Poland. A new station is situated near the Polish-Lithuanian border in Wigry National Park (north-eastern Poland).
