Some interesting lichenized fungi from old Fraxinus excelsior and Ulmus glabra in Norway, including four new country records

Abstract

A survey of lichenized and non-lichenized fungi, and bryophytes on old Ulmus glabra and Fraxinus excelsior trees in Norway was undertaken during 2012–2014. In total, 690 (400 elm, 290 ash) trees at 65 sites were surveyed and 675 records of 34 nationally red-listed epiphytic lichenized fungi were made (Nordén et al. 2015). Several species new to Norway were also found, three of which were reported in Nordén et al. (2013), and one in Nordén (2016). Reported here are four additional species as new to Norway, together with data on six rare species for which our findings contribute to the knowledge of their frequency, distribution and ecology. A few Swedish collections of the same species are also mentioned. All material is deposited in herbarium O. Abbreviations: BN = Björn Nordén, JBJ = John Bjarne Jordal.
