Notes: Lasiodiplodia was introduced by Ellis in 1894 with L. tubericola as the type species. Ellis did not provide a description of the genus and species, but this was provided by Clendenin (1896) who attributed both the genus and species to Ellis and Everhart. Griffon and Maublanc (1909) considered that Botryodiplodia theobromae was more suitably accommodated in Lasiodiplodia. Since the epithet theobromae (1892) is older than tubericola (1896), L. theobromae should be regarded as the type species of Lasiodiplodia. In earlier works on Lasiodiplodia and Diplodia it was considered that Lasiodiplodia could represent a possible synonym of Diplodia (Denman et al. 2000). However, in phylogenetic analyses these two genera were clearly separated in two distinct clades (Zhou and Stanosz 2001; Slippers et al. 2004a, b; Phillips et al. 2008). Lasiodiplodia is distinguished from Diplodia by striations on the conidia.

Conidiomatal paraphyses distinguishes Lasiodiplodia from Neodeightonia. Although Barriopsis has striate conidia, they are unique in Botryosphaeriaceae because they are also present on immature, hyaline conidia.
