Additions to the flora of lichenicolous fungi of Sweden

Introduction Currently 418 species of lichenicolous fungi are included in the Swedish checklist (Westberg et al. 2021). Numerous species remain to be found and during the past years efforts have been made to search for species that have not yet been documented from Sweden. In this paper, we report 15 lichenicolous fungi that are new to Sweden, mainly as a result of field work but also from searching collections in the lichen herbarium in UPS for lichenicolous fungi. Eight of these species are also new to Fennoscandia.Material and Methods Specimens were studied using a dissecting microscope. Anatomical features were examined on hand-cut apothecial sections and squash preparations mounted in water using a compound microscope. Measurements of ascospore dimensions and other anatomical features were made in water. Coordinates are expressed in degrees and decimals in WGS 84.
