A rarely found species in the Czech Republic. It grows on hard, periodically inundated substrates, such as slowly decaying wood in oligotrophic glacial lakes in the Šumava Mts; but also on wet bare soil, such as drying parts of raised bogs in the Jizerské hory Mts. It was also recorded on wet sandy soil of forest road banks in the České Švýcarsko National Park and Jeseníky Mts.
