Hypogymnia tubulosa (Schaer.) Hav.

A species with a similar distribution and ecology as H. physodes, often occurring in its company. However, H. tubulosa is slightly more sensitive to air pollution and requires slightly higher humidity, therefore it is generally rarer. It differs from H. physodes by capitate soralia at lobe margins and a rather shrubby thallus. Typically, the lichen is found on twigs of various wooden plants in well-lit habitats both within forests and outside them. It is common, for example, on shrubs in association with Xanthoria polycarpa. The species is abundant in the entire Czech Republic, from lowlands to mountains, but usually is not dominant in epiphytic communities in contrast to H. physodes or Parmelia sulcata.
