A saxicolous lichen of siliceous substrates. The occurrence of this species in the Czech Republic is unclear. Theoretically, we can expect its presence in our highest mountains. Although it used to be commonly reported in the past (see the Catalogue of Vězda & Liška 1999), the data probably relate to a similar taxon C. caesiocinerea, differing mainly by the thallus's chemistry (Wirth et al. 2013). According to some authors, C. gibbosa seems to be a Nordic taxon (e.g. Nimis et al. 2018). Data from our country require a detailed revision.
