The paper includes data on species, which were recorded by the author in Kamchatka since 1990 but mostly were not published. 19 species are new for Kamchatka, including Jungermannia evansii – new for Russia and Marsupella adusta – second record for Russia. Data on distribution, ecology and differentiation of Kurzia makinoana, mentioned as K. sylvatica for the first time for Russia from Kamchatka and Iturup Isl. (Konstantinova & al., 1992), are provided. The list of 12 species, which were omitted in the recent account of I. V. Czernyadjeva and A. D. Potemkin (2002) on bryophytes of the South-Kamchatka Nature Reserve (ÞÊÇ – 51°20’N 156°45’E), is provided. Coordinates of the other collecting localities in Kamchatka with corresponding Cyrillic abbreviations used in the text as follows: Central Kamchatka – ÂÊÈ (Upper Kerevna Hot Springs) – ca. 56°43’N 159°52’E; West Kamchatka Lowland – ÇÊÍ – 54°53’N 155°41’E; SW Kamchatka – Á (Bannaya River Basin) – 52°54’N 157° 30’E, ÁÍ (Interfluve of Bystroy-Bol’shoy and Nachilova Rivers) – 53°06’N 156° 53’E.

The species lists are annotated by data on localities and ecology of every species as well as by taxonomic consideration and notes on distribution of most interesting species.
