Enkele voor Nederland nieuwe blad- en levermossen in de Biesbosch

Metzgeria temperata, Cololejeunea minutissima, Cynodontium sp. and Orthotrichum rogeri are reported for the first time from The Netherlands. All were found on branches of Salix alba in extensive young willow forests in the Biesbosch (prov. Noord-Brabant and Zuid-Holland). The Biesbosch is the northernmost locality on the European continent for C. minutissima. The epiphytic habitat for Cynodontium is very unusual. It has not yet been found with mature capsules. The rare O. rogeri was found on four different sites. Other interesting finds were Metzgeria fruticulosa, not found in The Netherlands for many decades and Hedwigia ciliata, Orthotrichum rupestre and Leptodontium flexifolium as epiphytes.
