Abstract

Thelidium pluvium sp. nov. is newly described from rocks in streams in Great Britain, Ireland and Norway. It is characterized by perithecia which are partly covered by a thalline layer, a thin involucrellum, and 1-septate spores. A provisional key is given to species of Thelidium in north-west Europe.
