The dataset with 49,726 moss occurrences located predominantly on the territory European North-East Russia was described in this data paper. The dataset was based on the digitized bryophytes labels from the Institute of Biology of Komi Scientific Сenter of the Ural Branch of the Russian Academy of Sciences herbarium (SYKO). The information from the labels was recognized, cleaned and brought into compliance with the Darwin Core. More than 99.9% of occurrences were georeferenced with a precision of at least 3 km. For each record of occurrence the digital image of original label was attached. The dataset contains occurrences of 539 moss and liverworts taxa (with species and lower ranks) belonging to 190 genera and 75 families.
