The aerial algal growths on spruce needles in two localities located in the western and central parts of the Krušné hory Mts, which were characterized by different levels of damage caused by environmental pollution, were investigated. In total four species of green algae were encountered in algal growths (Apatococcus lobatus (CHODAT) PETERSEN, Pseudococcomyxa sp., Chlorella angusto-ellipsoidea HANAGATA, KARUBE & CHIHARA, Choricystis minor (SKUJA) FOTT).
In the western locality nearby Přebuz, where the phenomenon of "new forest decline" expressed by enhanced needle yellowing and shedding has been observed since 1999, the growths were more developed than in the central part locality in Kovářská. In addition, the coccal green alga Pseudococcomyxa sp. was present only in samples from the Přebuz locality, thus we hypothetize its bio-indicative importance.
