Abstract
The ecology, sociology and fruiting body production of larger fungi was studied at Kilpisjärvi in northwestern Finnish Lapland (69°05′N lat. 22°15′E long.) from 1976–83. The investigated habitats were subarctic (orohemiarctic) birch (Betula pubescens subsp. tortuosa) forests and low oroarctic heaths and snow beds just above the tree line and in the middle oroarctic zone. The middle oroarctic habitats were only observed from 1980–83. There were 17 permanent study plots of 100 m2 in birch forests and 12 in the oroarctic zone. Information is also given on the vegetation and soil conditions of the plots.
The identified genera in the habitats studied are presented. The total number of taxa identified in all the study plots was 219 (206 in birch forests and 58 in oroarctic habitats). The number of agaric genera was 46 (46 and 21 respectively). The greatest number of identified taxa (148) was found in herb–rich forests and the smallest (9) in middle oroarctic heath. The number of identified species will increase along with the progress of the determination work.
In the birch forests the most productive genera were Leccinum, Cortinarius subgenus Myxacium, Lacta ri us and Russula. In the low oroarctic heaths the most productive genera were Leccinum, Cortinarius subgenus Myxacium and Rozites, and in snow beds Entoloma and Amanita.
