Description:

Syn.: C. pyxidata ssp. chlorophaea Comment: Determination not certain. Generally, field characters of C. chlopolraea from literature fit well to pictures. However, habitus of the speciment shown shows narrower than usual cups and frequently inflated podetia stalks, which doesn't seem typical for C.Chlorophaea. Habitat: wood-side, mixed forest with dominant Fagus sylvatica, partly sunny, partly protected from direct rain by tree canopies, precipitations ~ 3.000 mm/year, average temperature 6-8 deg C, elevation 830 m (2.700 feet), alpine phytogeographical region. Substratum: bark of a partly rotten Fagus sylvativa stump and humus soil beneath it. Ref.: F.Dobson, Lichens, The Richmond Publ. (2005), p135.
