The sa:ricolous lichen flora on the island of Tiirno in the province of<br />
Blekinge, SE Sweden was investigated. Of the 64 taxa found, 46 occurred on<br />
gneiss and 47 on diabase. Five species which were absent on gneiss, were<br />
rather abundant on diabase in their corrresponding habitats, viz. Acarospora<br />
fuscata, Caloplaca thallincola, Lecanora achariana, L. campestris and<br />
Phaeophyscia sciastra. Three species which were absent on diabase, were<br />
rather abundant on gneiss in their conesponding habitats, viz. Arctoparmelia<br />
incurva, Caloplaca scopularus and Miriquidica deusfa. Possible reasons for<br />
the differences of the lichen vegetation on the two substrates are discussed.<br />
Lecanora rimicola isreported as new to Blekinge.<br />
