Notes – Leptosphaeria is typified with Leptosphaeria doliolum and is originally introduced as Sphaeria doliolum Pers. (Cesati & de Notaris 1863, Barr 1987a). The lectotype of the genus has superficial ascomata, flattened at base, papillate, thick, scleroplectenchyma tissue types of peridium, cylindrical asci with ellipsoid to fusoid ascospores with a coelomycetous asexual morph (Crane & Shearer 1991, Hyde et al. 2011, 2013). The morphological characters of the type species are given in Hyde et al. (2013) and phylogenetic analysis provided in Ariyawansa et al. 2015b and Dayarathne et al. (2015). The ITS, LSU, SSU, tef1 and rpb-2 sequence data for type species are available in GenBank database (Schoch et al. 2009a).
