Leptographium lundbergii was introduced from wood of Coniferae in Sweden. The strain was introduced as the asexual morph of Grosmannia (Lagerberg et al. 1927). de Beer et al. (2013b) synonymized Grosimannia under Leptographium. The genus causes sap-stain of mainly conifer timber, and less often of hardwoods (Harrington & Cobb 1988, Wingfield et al. 1993, Jacobs & Wingfield 2001). A few species are saprobes found in the soil or decaying plant material, and some are important tree pathogens (Harrington & Cobb 1988). Like most ophiostomatoid taxa, Leptographium spp. are best known for their association with bark beetles (Harrington & Cobb 1988, Kirisits 2004). They are adapted to be carried by these insects, having erect conidiophores or ascomata with long necks and conidia and ascospores produced in slimy masses at the apices of these structures (Six 2003, Kirisits 2004, Cardoza et al. 2008).

Type species: Leptographium lundbergii Lagerb. &Melin
