Chaenotheca hispidula (Ach.) Zahlbr.

A tiny lichen, characterised by the immersed thallus, containing photobiont from the genus Trentepohlia, and by the yellow-pruinose fruiting bodies less than 1 mm high. The species occurs mainly epiphytically, on various deciduous trees and less often on conifers. It may be found both in open and dense forests and even in parks. Chaenotheca hispidula prefers rain-protected places, such as the inclined tree trunks, their bases and bark crevices. It is a temperate lichen, widespread but rather rare in Europe. In the Czech Republic, it occurs rarely in well-preserved lowland to mountain forests. Recent reports come from the southern part of the country.
