Twelve species of lichens and lichenicolous fungi are reported as new to Fennoscandia. Additionally, we report 19 species as new to Norway. New localites are given for 47 rare or seldom collected species. The new combination Reichlingia anombrophila (Coppins & P. James) Frisch is proposed. Most collections were made in the boreo-nemoral and boreal rainforests during the NBIC funded project Three storied diversity – mapping and barcoding crustose lichens and lichenicolous fungi in the Norwegian rainforests and associated fieldwork in recent years. With the present contribution, we hope to raise awareness on previously neglected groups of lichenised and lichenicolous fungi and encourage further fieldwork in understudied habitats in Norway
