Abstract

Dactylospora aeruginosa Holien & Ihlen, sp. nov. is described from Norway and U.S.A. and D. borealis Holien & Ihlen, sp. nov. is described from Norway, Sweden, and U.S.A. Both species are lichenicolous, but D. aeruginosa is also saprobic on wood and bark of Picea abies and Juniperus communis, whereas D. borealis is only rarely growing on bark of P. abies. Notes are given on their ecology and distribution. A key to the known lichenicolous species of Dactylospora occurring in Scandinavia is included. Lichenodiplis lecanorae is suggested to be the anamorph of D. borealis.
