Absconditella lignicola Vězda & Pišút

One of the most common species of lignicolous lichens in the Czech Republic, occurring in various types of commercial and natural forests, as well as in parks. However, especially in the past, it was overlooked for its mushroom look resembling a small discomycete. It often occurs in similar pioneer epixylic synusiae as the species A. celata, accompanied by other pioneer crustose microlichens, non-symbiotic green algae and leafy liverworts. The usual substrate is moist, still undecomposed wood of mainly lying trunks, but also stumps of conifers or deciduous trees. It rarely passes on bark (tree bases, branches), polypores, etc. Infrequently, it has been recorded on an inorganic substrate (sandstone). It is widespread in the temperate and boreal zone of the northern hemisphere. Absconditella lignicola is markedly rarer in the oceanic and Mediterranean regions of Europe. Its probable optimum is mainly in northern boreal forests.
