Savoryella lignicola was initially described from test panels of Fagus sylvestris and Pinus sylvestris, exposed in a water cooling tower run with brackish water (Eaton & Jones 1971). This species can be commonly found in freshwater and marine environments. Taxonomically, Savoryella has been referred to several orders (Jones et al. 2016). Recently, Savoryella together with Ascotaiwania, Canalisporium (and its sexual morph Ascothailandia) formed a distinct clade in the Hypocreomycetidae (Sordariomycetes), based on phylogenetic analyses of the SSU and LSU rRNA, RPB2, and TEF-1-alpha genes (Boonyuen et al. 2011) (Figure 2). It can occur early in the colonization of timber test panels and also on well-decayed wood (Eaton & Jones 1971) and causes active soft-rot decay of wood (Mouzouras 1986).
