Pseudephebe pubescens (L.) M. Choisy

Pseudephebe pubescens is an arctic-alpine species which forms cushions of intertwined thin brown-black branches (filaments) on siliceous rocks and stones. In the Czech Republic, it occurs on open stands in mountains (the Šumava, Jizerské hory, Krkonoše, Králický Sněžník and Hrubý Jeseník Mts), rarely also at lower elevations with inverse microclimate (the Adršpašsko-teplické skály sandstone area). It used to be recorded in the Brdy hills and Krušné hory Mts in the past too.

According to recent studies (Boluda et al. 2016, Garrido-Benavent et al. 2021), P. pubescens is morphologically distinguishable from the closely-related P. minuscula (not recorded in the Czech Republic) only in polar areas. Consequently, the authors recommend that specimens without molecular data are identified as P. pubescens agg. There is no molecular data available for the Czech populations so far.
