Comment: Cladonia pyxidata is among the most common lichens in our region. The species is quite variable and its cups’ shape, podetia surface, as well as color may vary considerably depending on habitat. Particularly the differences between full sun and shady places are significant. It is not always easy to distinguish it from other similar species for me, most notably from Cladonia fimbriata and Cladonia chlorophaea. However, distinct corticate granules within the cusps (see picture 15b and Ref.4; also note English common name) makes me believe the determination of this find is quite reliable.
