Notes.

This species was originally described from bark beetle galleries and freshly cut surfaces of Picea mariana , Pinus resinosa and Pinus strobus in Canada ( Wright and Cain 1961). The Royal Ontario Museum Fungarium (TRTC), Canada, informed the authors of this study that the holotype (TRTC 36427) of L. sagmatosporum was permanently lost. There is also no living culture available from the holotype. We have thus designated the line drawings in the protologue as the lectotype. An isolate (CMW 34135), also from pine in Ontario, identified as L. sagmatosporum based on morphology (K. Jacobs, unpublished) and used in previous studies to represent the species ( Duong et al. 2012, Linnakoski et al. 2012, De Beer and Wingfield 2013), its dry specimen is designated here as the epitype.
