Lempholemma chalazanum (Ach.) B. de Lesd.

Lempholemma chalazanum is an inconspicuous calciphilous cyanolichen. Its thallus forms dark thin squamulose coatings with apothecia. If apothecia are missing, the species may be mistaken for less-developed specimens of Collema s. lat. The typical habitat of L. chalazanum is a bared calcareous soil, where it often grows in associations with bryophytes, or humus in rock crevices. It may occur also in anthropogenic habitats, such as walls or sand pits. It belongs to rather thermophilous species that are most often found in steppe grasslands. The lichen occurs sparsely at lower and middle elevations in the Czech Republic.
