Norwegian distribution: The species is known from a single locality in the upper, continental part of the Gudbrandsdalen valley in southeastern Norway - Counties:: Op. - Vegetation regions: southern boreal. - Altitude: 400-600 m

World distribution: Collema coccophorum is apparently a rare, but widely distributed species in dry areas of the world. Degelius (1954, 1974) listed localities from Europe, Africa, North America, South America, and Australia. In Europe, the species is known from Norway, Sweden, France, Germany, the Czech Republic, Hungary, and Slovenia. It was recently reported from Torne Lappmark as new to Sweden (Alstrup 1991)

Ecology: Results. No ecological data was indicated on the label of the Norwegian collection. Discussion. The site is a south-facing slope, probably grazing land, and one of the richest for the 'steppe element' in Norway. The climate is strongly continental, with a yearly precipitation of 400-500 mm (cf. Førland 1993). The bedrock is calciferous, consisting mainly of greenstone, phyllite and mica schist. According to Degelius (1954), Collema coccophorum is a terricolous species, growing on naked, more or less calciferous soil (clay, sand, weathered gypsum, etc.). A similar habitat is assumed for the Norwegian specimens

Threats: Results. Assumed threats were overgrowth by vascular plants (1) and trampling (1). Discussion. The species is probably a pioneer, requiring open soil. If the species still exists at the site, land-use change resulting in overgrowth by grasses and shrubs may be a threat, as well as excessive trampling by cattle

Status: The single Norwegian collection was made in 1863 (Degelius 1954), and the species has not later been observed in Norway. The locality is situated within the Vistehorten nature reserve

Notes: The species is not treated in the Swedish red list..
