( Figs 1C View FIG ; 2 View FIG ; 5A View FIG ; 6 View FIG ; 7 View FIG ; 12 View FIG )

It is characterised by the presence of atranorin, perlatolic acid (major), ± imbricaric acid (minor) and anziaic acid. The lack of 4-O-demethylimbricaric acid is obvious and well observable already under UV 254 nm after developing the HPTLC plate ( Fig. 2 View FIG ). Its soredia are fine [25-35(-40) µm in diam. – Obermayer & Mayrhofer (2007)], 32.3 ± 3.4 µm in Hungarian samples. Not or slightly raised pseudocyphel - lae of various size (c. 30-300 µm) occur on upper cortex, smaller ones on lower cortex. Its specimens were found most frequently on oak ( Quercus sp. – 38%), beech ( Fagus sylvatica L. – 15%) and other tree species (46%) at lower elevations than in Austria ( Obermayer & Mayrhofer 2007), mostly at 200-600 m a.s.l., though in Belarus it occurs at even lower elevation ( Bely et al. 2014). This species proved to be less frequent than expected ( Figs 6 View FIG ; 7 View FIG ), and was previously confused with C. monachorum . Cetrelia cetrarioides is considered here as a critically endangered (CR) species in Hungary.
