Atractosporocybe polaris – a new clitocyboid agaric described from arctic-alpine and northern boreal regions in Svalbard and Scandinavia

The new species Atractosporocybe polaris, identified from the arctic archipelago of Svalbard and Scandinavia, is here described as new to science based on ITS and LSU sequence data from nuclear ribosomal DNA. In morphology it differs from A. inornata by darker gills, a smooth or faintly grooved cap...

Description
Summary:The new species Atractosporocybe polaris, identified from the arctic archipelago of Svalbard and Scandinavia, is here described as new to science based on ITS and LSU sequence data from nuclear ribosomal DNA. In morphology it differs from A. inornata by darker gills, a smooth or faintly grooved cap margin, and a comparatively faint smell. It grows in arctic tundra and heathland among mosses, lichens, ericaceous plants, herbs, graminoids, and dwarf Salix and Dryas on calcareous ground. In Scandinavia it is found in the northern boreal zone growing among Salix scrubs and Alnus.
