Fungi are on the priority groups for OHBR as they have not been widely recorded in the past. The database includes records of macro-fungi (mushrooms, toadstools, brackets) and micro-fungi (mildew, moulds, rusts, smuts). Over 490 species are illustrated on the Outer Hebrides Fungi website, which includes photographs of microscopic characters but not distribution maps.
The slime moulds belong to the phylum Myxomycota, which is part of the fourth kingdom Protista. They have been included with the fungi for convenience. They are difficult to identify and we currently have very few records.
