Coenogonium luteum (Dicks.) Kalb & Lücking

Thanks to the yellow apothecia, C. luteum is a relatively conspicuous lichen. It grows on deciduous trees, especially on their mossy trunks. Abroad, it has been reported also from mossy rocks and soil. In central Europe, it is a rare species, linked to old-growth forests in areas rich in precipitation. The lichen is sensitive to substrate acidification and air pollution and requires a specific forest structure (humid microclimate, well-lit old trees). Hence, it may be considered a good indicator of well-preserved habitats with high epiphyte diversity. Until recently, this species had been considered extinct in the Czech Republic. However, a few new localities were found in the Šumava Mountains in the last years.
