Distribution, status and ecology of the lichen Cyphelium notarisii in Sweden

Abstract

An inventory of the two largest Swedish occurrences of the lichen Cyphelium notarisii, situated on Visingso in Smaland and at Kovik on Gotland, respectively, was conducted. A third occurrence on Faro, Gotland was discovered. A total of 21 localities were visited. Only cultural substrates such as wooden barn walls, fishing sheds and gates were utilised by fertile specimens. The species is mostly found on south- to southwest-facing walls with no shade cover, close to a water-body. The current distribution is greatly reduced compared to the historical range of the species. The major current occurrences are characterised by a high concentration of old wooden structures, which strongly indicates that measures to ensure the viability of the species' should be taken at the landscape level, rather than on individual localities. Cyphelium notarisii is reported as new to Estonia and Kazakhstan, and C. tigillare is reported as new to Gotland, Sweden
