New and interesting Myxomycetes from Norway

Forty–nine species of myxomycetes are reported as new to Norway. Of these, 22 species are new to Scandinavia. Several have not, or only rarely, been reported from Europe. Two species (viz. Diderma subfloriformis and Comatricha anomala) were previously known only from their type localities. Brief discussions are given for some of the more interesting species.
