Usnea hirta (L.) F.H. Wigg.

One of the most common Usnea species in the Czech Republic. It is distinguished by matt smooth branches, absence of papillae, pale thallus base, characteristic isidia and the presence of murolic acid complex in the medulla. The species is widely distributed in Europe. It is apparently more tolerant to air pollution than other Usnea species. It can be found scattered on acidic tree bark and sometimes also on snag wood inside and outside the forests in most of the Czech Republic.
