Lecidella elaeochroma (Ach.) M. Choisy

A very heterogenous genus member, possibly covering more individual taxa. The light thallus contains xanthones (C+ orange), but sometimes these are present only in low concentrations (C-) or not at all. Such forms are usually called L. euphorea. The thallus may be even richly sorediate (f. soralifera). Large variability is also apparent in apothecial anatomy, especially in the presence of droplets in the hymenium and hypothecium. Forms with inspersed hymenium (i.e., with droplets) are sometimes recognized as L. achristotera. Other names from this complex accepted by some authors at the species level are L. laureri and L. tumidula. Within this atlas, we do not generally distinguish these minor taxa.

Lecidella elaeochroma is an epiphytic species abundant on smooth bark of deciduous trees, and rarely, it may also be seen on conifers or wood. The species occurs in both forest and non-forest habitats at any elevation. The lichen is distributed across the whole Europe. In the Czech Republic, it is a common species in some areas, but in areas with a high sulphur dioxide fallout in the past, it is very rare or has even disappeared entirely.
