A rare basidiolichen, hardly mistakable for other species, growing over bryophytes, humus, acidic soil, peat and sometimes on decaying wood or sandstone rocks. Most often, the species is found in mountains, in permanently humid microhabitats in naturally forestless areas. It may occur also at lower elevations if suitable biotopes (such as permanently humid deep valleys and peat bogs) are available. The lichen has a circumpolar-mountain distribution. In the Czech Republic, L. hudsoniana is rare, recorded usually at higher elevations. Recently, it has been reported from the Krkonoše Mts, Hrubý Jeseník Mts, Orlické hory Mts, Šumava Mts, České Švýcarsko National Park and the Broumov region. In the 1990s, it was found also in the Žďárské vrchy Hills and Rakovník region (Zmrhalová 1990, Kocourková-Horáková 1998). Older historical records refer also to other regions (Krušné hory Mts, Jizerské hory Mts, Králický Sněžník Mts and the regions of Doksy and Třeboň).
