Pteryngium crenatum is newly recorded in Nova Scotia and Atlantic Canada (Fig. 2). This species has previously been recorded in North America from British Columbia, Indiana, New Hampshire, Oregon, Québec, and Washington ( Bousquet 1991; Downie and Arnett 1996; Chandler 2001). It is an adventive Palaearctic species found throughout Europe ( Johnson et al. 2007). In Nova Scotia, all the specimens were collected in coniferous forests, most on bracket fungi ( Polyporaceae ).
