Amylocystis lapponica in Norway, an indicator species for species-rich continuity forests.

The wood-inhabiting fungus Amylocystis lapponica is classified as vulnerable (V) in the Norwegian red list. Until 1992 the species was known only from one locality in Norway, but during the nineties, more localities have been discovered, mainly in the south-eastern parts of Norway. In spite of the fact that most of the known localities apparently have small populations of the species, only 1-2 fruit bodies having been seen, it is possible to state something about the species’ ecology in Norway. All the investigated localities are in old-growth forest of Norway spruce Picea abies, or of a mixture of spruce and pine Pinus sylvestris. The continuity of dead wood is good, with mainly few and old cut stumps. Other red listed wood-inhabiting fungi are regularly detected in the Amylocystis lapponica localities as well. These observations lead the group of field biologists, Siste sjanse ("Last chance"), to the conclusion that Amylocystis lapponica is one of the best species of a set of indicator species that may be utilized to point out species-rich spruce forest areas in special need of conservation.
