Lecidella flavosorediata (Vězda) Hertel & Leuckert

A Lecidella species with more or less yellow sorediate thallus containing xanthones (C+ orange) and occasionally forming black apothecia. Lecanora expallens and Lecidella subviridis are very similar, therefore TLC is usually necessary for their identification.

Lecidella flavosorediata prefers a rather subneutral bark of deciduous trees. It occurs in open countryside and well-lit forests from lowlands to mountains. In central Europe, it is one of the sparse to locally abundant lichens. The species was described for science from the Krkonoše Mts by Antonín Vězda. However, it is still a more or less overlooked lichen in the Czech Republic. There is a lack of data from the northern part of Bohemia, where it probably significantly declined due to substrate acidification in the second half of the 20th century.
