Verrucaria velutinoides (Lichenes, Verrucariaceae) near Tbruri (N Poland)

摘要

Verrucaria velutinoides Hell, has been known for a long time from higher mountain sites on the Czech side of the Eastern Sudeten For that reason it had been anticipated that it would be found in the Sudeten (Nowak & Tobolewski 1975) rather than in thefar away region of Kujawy in northern Poland. The new locality of the species, found in 1994, is situated south-east of Torun in an old sandpit in a dune covered area by the crossing of the Torun- Bydgoszcz motorway with the Torun - Inowroclaw railway line, The lichens in the site form their own initial communities and enter the association Festuco-Koelerietum glaucae Klika 1931, consisting mainly of Festuca psammophila (Hack, ex, Celak.) Fritsch, Koeleria glauca (Spreng.) DC. and numerous specimens ofTragopogon floccosus W. & K. Among them grow Cetraria islandica (L.) Ach., Coelocaulon aculeatum (Schreb.) Link., Placynthiella oli-gotropa (Vainio) Coppins & P. James, P. uliginosa (Schrad.) Coppins & P. James, Diplo-schistes muscorum (Scop,) R. Sant.and many species of the genus Cladonia Wigg.
