Rather a rare member of the genus Biatora in the Czech Republic, with less than 20 recent localities. It occurs mainly in well-preserved moist submontane and mountain deciduous forests near watercourses. Less often, in highly forested areas, such as the Šumava or Novohradské hory Mountains, it also inhabits shady mixed and deciduous forests on less elevated peaks and slopes, either old-growth forests (often scree forests) or wetter beech plantations. It usually grows on smooth bark of younger deciduous trees at their bases. It is often accompanied by other members of the genus, such as B. helvola or B. efflorescens. Recent reports come, besides south-western Bohemia, only from the Orlické hory Mountains.
