The geographic focus of the lichen collection is Norway with Svalbard, and this make up about 80 % of the collection. Most of the specimens are registered in the database. A significant part of the collection is from the period after 1980 and includes many interesting specimens from the boreal rainforest of Central Norway.

Most specimens from outside Norway are from the Nordic countries. From other parts of the world the specimens from Africa collected by Ove A. Høeg are of special interest.

The genera Bryoria and Cladonia as well as pin lichens in a wide sense, i.e. genera like Calicium, Chaenotheca, Sclerophora etc are well represented in the collection.

About 200 type specimens are included in the collection.

Important exsiccatae includes: Cladoniae exsiccatae, Heinrich Sandstede Lichenes selecti Scandinavici exsiccati. Adolf Hugo Magnusson
