Lichenen in de Kop van Noord-Holland (2)

An investigation of epiphytic lichens was made in a small broad-leaved forest in the northern part of the province of North Holland. Five Red List species were found: Enterographa crassa, Graphis scripta, Hyperphyscia adglutinata, Physconia distorta and Pertusaria hymenea. The last-named is a rare species in The Netherlands, Enterographa crassa and Graphis scripta are moderately rare. Hyperphyscia adglutinata appears to be no longer a rare but a rather common species. The distribution of Lepraria lobificans is still unclear at the moment.
