Distribution. Widespread in Europe and Russia, including Siberia and the Far East.

Status in CZ. Previously known only from Bohemia: Aš, Františkovy Lázně (all Kowarz 1884 and Vimmer 1913), Šumava Mts ( Hulcr et al. 2005), Krkonoše Mts ( Naglis et al. 2016a), and Vráž ( Naglis et al. 2016b). The first records from Moravia are listed herein. The specimen from Podmolí (Liščí skála) was incorrectly identified as M. glauca and recorded as such by Olejníček et al. (2005).

Ecology. In the Czech Republic, this species is found mostly on tree trunks of both coniferous and deciduous trees, but also on stones/boulders, in sunny forest margins and clearings, widespread from lowlands to mountains (180–1200 m a.s.l.). Medetera infumata has also been collected in numbers on rocks and logs in the clearing of a coniferous forest in Belgium (see also Pollet et al. 2011).
