This research presents the results of a study of diversity and ecological peculiarities of algae inhabiting sandstone walls in hypogean casemates of the city of Luxembourg. A total of 59 taxa belonging to four divisions of algae were revealed: Cyanoprocaryota = Cyanophyta − 15, Chlorophyta - 30, Bacillariophyta - 10, Eustigmatophyta - 2. Unicellular and filamentous chlorophytes together with filamentous cyanobacteria dominated in species composition. Culture-based observations are presented on a number of noteworthy and poorly described taxa. It was found that species composition of hypogean algae is heterogenous: each studied gallery is inhabited by several algal communities. Two ecological groups, trogloxenes and troglophiles, are represented in studied species composition. Trogloxenes make up 60% of revealed species of algae. It is shown that species composition of algae of the casemates has more in common with those of open-air sandstone substratums than with species composition of algae of lime caves.
